Therefore, knowledge and understanding of the pathogenetic basis of OSA are important to implement new therapeutic strategies. As the genioglossus (GG) is the main dilator muscle of the upper airway, increasing the activity of this muscle and preventing hypotonia during sleep would be a promising therapeutic approach. The aim of this review is to describe and evaluate the evidence that supports new strategies targeted to improve GG dilator function in an attempt to increase upper airway patency in OSA patients.

Wallerian degeneration is minimized within 1 to 2 weeks after damage occurs, and it is important to promote nerve regeneration in an appropriate direction in order to obtain a good prognosis. Therefore, if the nerve is damaged, medical evaluation and treatment should be performed as soon as possible. Specialist attention should be sought within 1 to 2 weeks after damage occurring and treatment commenced. Figure 7 shows the difference in prognosis by treatment start date. The number of patients who achieved complete remission, meaning an almost complete recovery, increased the earlier treatment started, whereas the majority of those in whom treatment was commenced at 6 months or more after nerve injury occurred showed either no change or exacerbation. If the nerve is damaged, evaluation and treatment should be started within a month to obtain a good prognosis.

Subsequent steps to control anterior nasal bleeding most often include vasoconstriction, in which cotton pledgets soaked in vasoconstrictor and local anesthetic are placed in the anterior nasal cavity and direct pressure is applied to both sides of the nose for several minutes. If bleeding continues, more aggressive approaches may include chemical cautery using silver nitrate, electrocautery, hemostatic packing with absorbable gelatin foam or oxidized cellulose, or treatment with a fibrin glue. Posterior bleeding is less common and often more severe than anterior bleeding and is usually treated by an otolaryngologist; management approaches typically involve posterior packing or alternative packing strategies using various balloon systems. The most persistent cases of anterior or posterior bleeding may require arterial ligation or embolization.

Inferior alveolar nerve damage can lead to mild to severe paresthesia and even facial pain. One of the treatments considered today for the reconstruction and treatment of damaged peripheral nerves is the use of vitamin supplements. This study aimed to evaluate the effect of vitamin B complex supplementation on pain and sensory problems following mandibular implant placement surgery.

The first screw will be the most proximal one and will be placed as high as possible without invading the joint capsule. The joint line can be used as a reference to place it parallel to it. Subsequently, we proceed to implant the most distal screw of the frame. Once these two elements have been placed, the remaining ones will be guided by the heads of the fixator and their implantation will be routine.

Obstructive sleep apnea is a potentially dangerous condition with significant risks of comorbidities if left untreated. It represents a cardiovascular risk factor in the general population, and a higher prevalence is observed in patients already suffering from cardiovascular diseases. The gold standard treatment, continuous positive airway pressure, is not always accepted or tolerated. The mandibular advancement device represents an alternative treatment that we propose to implement in our study. The objective here is to first present a brief review of the topic. Due to poor evidence in the field, we propose a pilot study to evaluate the effect of a mandibular advancement device in patients with cardiovascular disease who are not treated for their sleep pathology in order to improve their therapeutic management.

Review of literature yielded scarcity of occipital anatomy analysis of the Malay ethnicity. The Malays ethnicity are predominant in regions around the South China Sea which includes Malaysia, Indonesia and the Philippines. Therefore, a comprehensive mapping of the Malay occipital thickness can give a clearer idea for the Malay ethnicity as previous recommendations from studies in patients of other ethnicity and regions may not be applicable. The study hypothesis was that the smallest diameter 8mm screw should be feasible for the Malay population. The primary objective of this study was to determine mean occipital thickness amongst the Malay ethnicity. This in turn sets a reference map for safe screw placement of at least 8mm when dealing with patients of Malay ethnicity during occipitocervical fusion. As there have not been any previous studies with regards to the Malay ethnicity, this study can serve as a guide to surgeons placing screws in the occipital region.

The ARI scoring system is an assessment tool used to investigate adhesive systems. It is a quick and simple method that does not require special equipment . Results in the current study have shown the prevalence of scores 2 and 3 in the RMGIC group in comparison to the R group, which presented a prevalence of scores 0 and 1 (Table 4); this result corroborates the previous study , which found similar results. One hypothesis for these findings is that the use of fluorides to prevent caries promotes the incorporation of fluoride ions in the hydroxyapatite crystal network of hard tissues and leads to a mineral phase less soluble and more resistant than hydroxyapatite.

NSD was observed significantly higher in the asymmetric group. It seemed that bony interference caused by advance of setback difference of a bone fragment may exert compressive force on the inferior alveolar nerve, so NSD is expected to occur more frequently on the interfered side. So preoperative facial asymmetry might be one of the affecting factors in immediate postsurgical NSD.

Demyelination in MS disrupts nerve signals and contributes to axon degeneration. While remyelination promises to restore lost function, it remains unclear whether remyelination will prevent axonal loss. Inflammatory demyelination is accompanied by significant neuronal loss in the experimental autoimmune encephalomyelitis (EAE) mouse model and evidence for remyelination in this model is complicated by ongoing inflammation, degeneration and possible remyelination. Demonstrating the functional significance of remyelination necessitates selectively altering the timing of remyelination relative to inflammation and degeneration. We demonstrate accelerated remyelination after EAE induction by direct lineage analysis and hypothesize that newly formed myelin remains stable at the height of inflammation due in part to the absence of MOG expression in immature myelin. Oligodendroglial-specific genetic ablation of the M1 muscarinic receptor, a potent negative regulator of oligodendrocyte differentiation and myelination, results in accelerated remyelination, preventing axonal loss and improving functional recovery. Together our findings demonstrate that accelerated remyelination supports axonal integrity and neuronal function after inflammatory demyelination.

In conclusion, this study demonstrated a significant increase in surgical accuracy over time which supported the presence of a learning curve in 3D virtual surgical planned orthognathic surgery. An unfavorable learning curve was associated with posterior maxillary impaction and a larger magnitude of jaw movement. The awareness of a learning curve in 3D virtual surgical planned orthognathic surgery can be beneficial for oral and maxillofacial residents and surgeons. It provides information on the expected level of surgical accuracy when starting to use 3D VSP, the potential for improvement with practice, and the final level of precision that can be achieved. Authors suggest that future research should focus to examine the entire learning curve over a longer period, to determine when the plateau in surgical accuracy can be reached, and to correlate the level of surgical experience with the learning curve in virtual planning.

The purpose of this temporary antibiotic PMMA spacer is to deliver high concentrations of local antibiotic while simultaneously preserving space for the definitive osseous reconstruction, to greatly enhance mechanical stability and to create an induced membrane that has biological activity and encourages bone graft incorporation by containing the graft and providing a more receptive recipient bed. The PMMA spacer should remain in the defect approximately 8–12 weeks. While the membrane develops, this intervening time period is used for virtual surgery and planning for secondary reconstruction, including design of a truss cage suitable for a given anatomic location. Consideration must be given to the type of skeletal stabilization that will be employed in the definitive construct (intramedullary (IM) nail or internal fixation using a plate and screws).

In contrast to true abdominal aortic aneurysms, pseudoaneurysms are classified as false because they generally lack all layers of the vessel wall. The form they subsequently develop is secondary to the products of the clotting cascade, which form a wall and lead to containment of blood. The lack of the robustness of a real vessel wall means that these pseudoaneurysms are fragile and must be treated without delay, regardless of their size.

A total number of 25 patients were retrieved and, among them, 10 patients were selected, in which planning inaccuracy caused difficulties during implant placement and which then led to induced changes during the planning of similar cases or in which the problems were noted before or during the planning which led to changes in the plan to address those problems.

The position of the hyoid bone and tongue on cephalometric analysis and the anteroposterior width of the pharyngeal region did not change between the preoperative and postoperative periods. This indicates that the anatomical landmarks in cephalometric photographs may be associated with swallowing function. Furthermore, there was no difference in the position of the hyoid bone or width of the oropharynx two months postoperatively when compared to preoperatively. This could be due to the recovery of eating and swallowing functions and harmonization of the oropharyngeal region after surgery.

The SEM images were used not only to compare the enamel surfaces after two different adhesive removal techniques but also compare these images with the enamel surface of the intact tooth in the current study. The investigation of microstructure of the tube base, its possible effect on enamel cracks, and evaluation of adhesive remnants after debonding could be counted among the other benefits of SEM. The SEM images were taken after cleaning the surfaces either with TCB or PoGo micropolisher systems; therefore, adhesive remnants could not be located on enamel surfaces on any of the samples tested. Indeed, the main point of choosing SEM as a diagnostic tool for our study was to make the comparison of enamel surfaces after adhesive removal.

The use of a self-etch primer for simultaneously etching and priming the enamel reduced, but could not completely eliminate, the enamel damage and amount of remnant adhesive left on enamel after sapphire bracket debonding. Exposure of sapphire brackets bonded with a SEP to thermocycling and then cyclic loading reduced the bond strength, yet it was within the range suiTable for clinical performance. The shorter bonding time combined with the potential to produce less remnant adhesive and enamel damage render the SEP approach a suiTable alternative to the aggressive PA gel for enamel conditioning before sapphire bracket bonding.

In the present study prosthodontics treatment was the indication for RP modelling in 22%. For prosthodontics treatment with implant based rehabilitation CBCT is frequently used nowadays. However, in the most severe cases with patients that have difficult anatomotophographic conditions this tool is not sufficient enough. In these cases the RP models can make the surgical planning easier. The functional occlusion and aesthetics of the dental implant treatment always depend on both jaws, the orthognathic relation between the mandibula and maxilla as well as the relation between the alveolar ridges and surrounding soft tissues. The 3D modelling facilitates the planning simply since all skeletal relations are clearly visible at once. Demanding planning for implant placement with need for augmentation and osteotomies can thus be visualized more clearly by using 3D models and modified treatment options for e.g. in patients with clefts or reconstruction with microvascular composite flaps can be planned safer with less risk of complication than planning based on (CB)CT examinations only. The final implant placement often needs guiding splints that can be manufactured based on the model and CT data as well.

On the contrary, the reported lack of total loss of the retainer during the period of observation reflects the close control of the bonded devices. This depends on the fact that all those followed were patients of a single clinician, who were regularly seen for hygiene, recall at least once a year, when the hygienist inspected the appliance and reported initial composite fractures or losses. This indicates that regular inspections are important to guarantee appropriate maintenance of these devices.

The heart rate mean did not decrease significantly from NREM to REM during CPAP studies. This result is similar to previous studies in healthy individuals [24]. The decrease HRV from NREM to REM was seen in basal studies, which suggests that OSA may influence the variance of the heart rate, but does not vary the natural change of overall beats per minute from NREM to REM. The lack of change in HRM during the CPAP study suggests that CPAP treatment lowers the variance of heart rate during NREM, as well as eliminates the change in the heart rate between NREM and REM.

The proper knowledge of etiology and predisposing factors is necessary for early recognition and suitable treatment of patients who are at risk of permanent anterior tooth fracture. The present study shows that maxillary incisors are most commonly fractured tooth and as generally people are right handed, so the frequency of fractured right maxillary incisors were more than any other permanent tooth which is in agreement with the studies done by Baldava and Anup, Johnson and Ravn. Zuhal et al have reported that the most affected age group was of 9 to 11 years old for sustaining permanent anterior tooth injuries and various other studies showed up to 12 years as more prone age group. So, we took an age group of 9 to 13 years old for our study and found that frequency of tooth fracture increased with increasing age. The possible reason being that with increasing age the child becomes more inquisitive and wants to explore new activities and areas untouched where chances of sustaining injury are more.

Conventional adhesive system use 3 different agents an enamel conditioner, a primer solution, and an adhesive resin and to bond orthodontic brackets to enamel (1,2). A unique characteristics of some new bonding systems in operative dentistry is that they combine the conditioning and priming agents into a single acidic primer solution. Combining conditioning and priming into a single step improves bonding time and reduce the number of steps during the bonding procedure and result in cost-effectiveness to the clinician and indirectly to the patient with similar bond strengths or even higher bond strengths.

Given the rising costs of healthcare, the continued development and implementation of AI-assistance into clinical decision-making is a likely inevitability. This domain has highlighted some of the ethical issues that may arise with the implementation of these systems and the relevant values that decision-makers can draw on in the design and implementation of AI-assisted CDSS into practice. Specifically, the values of professional integrity and accountability will play most prominently at the level of patient care, while values of justice and the potential for group harms must be balanced against the imperatives for public benefit at the societal level. The value of transparency cuts across both with trust in the medical profession and healthcare systems at stake.

We manage our cases with nasal packing, cautery, and surgical exploration. The most important step in our treatment algorithm is to try to find the source of bleeding with an endoscopic nasal examination. Initial attempts should aim to control the bleeding with chemical cautery or nasal tampons, but hospitalization and surgical intervention may be needed if bleeding persists. Cranial nerve deficits are important signs in skull base epistaxis and the attending physician must be vigilant about this condition. Such patients may need angiography with embolization.

The risk of coronary artery disease and cerebrovascular disease is more in patients with obstructive sleep apnea. Obstructive sleep apnea is characterized by repetitive episodes of complete or partial upper airway collapse resulting in intermittent hypoxemia and inflammation. Intermittent hypoxemia probably leads to increased sympathetic activity . Hypoxia-reoxygenation leads to the generation of free radicals resulting in oxidative stress which along with the resultant endothelial dysfunction may trigger the coagulation cascade.

It is common knowledge that fluoride therapy reduces enamel demineralization and increases its resistance to organic acids. Fluoride has a facilitating effect on the diffusion of calcium and phosphate ions into the demineralized surface. Thus, it can restore the crystalline enamel structure composed of fluorinated hydroxyapatites and fluorapatites, which are more resistant to acids than the primary crystals.

One major conclusion is that screws surrounded by higher bone density have higher resilience. This was shown in the study by Cornaz et al. who demonstrated increased retention in the pedicle at higher bone density for spine screws, in the study by Mischler et al. on the humerus who achieved better retention by adjusting the screw trajectory in areas of higher bone density, but also in the study by Fu et al. who indicated that anchoring of the screw in the cortex in the calcaneus is essential. Although this finding seems obvious, it appears to be of immense importance to incorporate it into current orthopedic techniques. Preoperative computer models that optimize and plan patient-specific screw trajectories, generic trajectories that lead to areas of higher bone quality, or implants that allow more targeted anchorage in cortical bone could therefore prevent problems with screws breaking out in the bone in the different areas.

Is it possible to reliably identify those Class III patients who may benefit from early treatment in the long term? Numerous cephalometric studies comparing outcomes at the end of adolescent growth with the original presenting malocclusion have attempted to create algorithms that may make this prediction in childhood possible. However, significant individual variation in facial growth patterns mean that this is difficult, especially for those cases where early treatment is ultimately unsuccessful.15 However, it does appear that high angle cases with increased lower anterior face height and reduced overbite at the start of treatment are more likely to respond poorly to early treatment and ultimately outgrow the positive effects of it.

Considering the limitation of this in vitro study, it can be concluded that the combined bleaching with a high concentration of hydrogen peroxide exhibited no effect on Silorane composite while it had an adverse effect on the sealed and unsealed methacrylate composite in terms of microhardness. The prior sealing, then bleaching and followed polishing would re-establish the surface hardness of the methacrylate composite. Therefore, it is safe to suggest that using a surface sealant on restorative materials prior to bleaching presents a preservative function against any adverse effect of the bleaching agents.

A prospective study conducted on 53 canines of 31 subjects assessed a mean accuracy for canine rotation of 36%. Canines that received interproximal reduction (IPR) reported the highest mean rotational accuracy and lowest standard deviation (43%; SD = 22.6%).
In Kravitz et al. the accuracy of rotation for maxillary canines was 32%, lower than that of the maxillary central incisors (55%) and mandibular lateral incisors (52%). The least accuracy was detected for the mandibular canine (29%). For rotations greater than 15° the accuracy of maxillary canine movement was significantly reduced (19%; SD = 14.1%; P < .05). Similar results were achieved by Simon et al., who demonstrated that staging (amount of rotation/aligner) also had a considerable impact on the treatment efficacy: for premolar rotations with a staging of <1.5°/aligner, the total efficacy was 41.8% (SD = 0.3%), whereas with a staging of >1.5°/aligner, the accuracy decreased to 23% (SD = 0.2%).

Despite the fact that oral appliances can be employed in a variety of OSA patients, they have a number of limitations, including the absence of enough teeth in the maxillary and mandibular arches. A tooth is thought to be especially crucial for ensuring the stability and retention of the mandibular advancement device. The condition of edentulism inherently exacerbates OSA and limits the number of viable therapies [39]. However, a review of the literature finds that only a few papers describe the use of MAD in the treatment of edentulous patients or patients with multiple missing teeth with OSA [40]. Some modifications are a must in the basic design of MAD in such patients. But CMOA can be successfully used not only in patients with fixed but also patients rehabilitated with a removable partial prosthesis as it takes major retention from the palatal slopes as does the removable partial dentures.

Negative intrathoracic pressure during apneic episodes may be associated with the development of AF. The Mueller maneuver was performed on healthy adults to simulate the changes in the upper airway, which occur during OSA and found that the negative intrathoracic pressure led to a decrease in the left atrial volume, increase in left ventricular systolic function and an increase in the ventricular afterload. These dynamic changes can be implicated in the development of AF. Repetitive cycles of negative intrathoracic pressure also lead to atrial stretch, which contributes to the enlargement of the chambers and development of AF. Negative intratracheal pressure causes shortening of the atrial effective refractory period through vagal stimulation, which also predisposes to the development of AF.

Some research groups have noted that potentially inherited abnormalities of ventilatory control may predispose to obstructive or central sleep apnea by influencing ventilation during sleep and increasing the propensity to upper airway collapse. Altered ventilatory drive also may precipitate apnea by promoting ventilatory control instability and, subsequently, periodic breathing. Ventilatory control instability could result from either blunted or augmented chemosensitivity.

Although the ODI is a good metric to determine the severity of the occurrence of desaturation events, it provides a summary of the information of the whole night and does not account for the variability introduced by other factors. For instance, it is known that position plays an important role on the occurrence of apneic events [20,21], which are usually accompanied by hypoxia. In this scenario, the combination of the information on the sleep position obtained from the ‘SleepPos’ app allowed linkage of the occurrence of the desaturation events to its sleep position angle of occurrence. This combination revealed very useful clinical information about the subjects of the database in two different variables: the local ODI and the ratio of the percentage of events versus the percentage of time spent at a specific sleep position angle. These variables allowed us to assess two important aspects: the severity according to the number of desaturations found and the positional behavior. The severity is evaluated by the local ODI and indicates how critical is the situation regarding to the occurrence of hypoxic events, and the positional behavior is assessed by the ratio and indicates if there is a sleep position where these hypoxic events are more prevalent.

Virtual surgery planning is best described as an online collaboration between the surgeon, the orthopaedic engineering professional and the biomedical design engineer. During this planning session, the patient’s bony anatomy is studied and manipulated to restore to normal before discussing the implant solution and method of fixation. The surgeon explains the indication and the expected approach, and instructs the engineers on the desired surgical technique. Some surgeons prefer to look through the individual slices of the CT scan, suggesting they have less confidence in the reliability and accuracy of the 3D model; other surgeons have explicit trust in the fidelity of the 3D model. It is often useful to have some transparency in the model to be able to fully assess certain aspects of the pathoanatomy during the planning session.

Open bite is a challenging malocclusion to treat, with a high incidence of relapse. Extrusion is the least accurate tooth movement to perform with CAT, and it can result in larger deviations compared to other movements. This lack of efficiency could be due to the difficulty of the appliance in developing enough force to extrude teeth in a significant way. However, PAR and OGS scores revealed that aligners were as successful as fixed appliances in controlling vertical buccal occlusion, even years after the end of treatment.10,11,14,17 Thus, on the basis of the existing literature, CAT is not recommended to treat open bite.

Previous studies using transcutaneous electrical stimulation for the treatment of sleep apnoea did not apply electrical current for the whole night. The TESLA data on patients' perception importantly highlight the feasibility of the method, with patients remaining asleep with no difference in their sleep profile compared with sham stimulation. Sleep quality was not adversely affected. Following the sham stimulation, patients complained more about a dry mouth in the morning than after active treatment. Whether this is a feature of a more patent upper airway at night or the mouth being closed remains to be elucidated.

ChatGPT can be a boon for medical education and research. It has the potential to provide instant access to a vast amount of medical information and can assist medical students and researchers in analyzing complex medical data. Additionally, ChatGPT can provide personalized learning experiences for medical students by tailoring information to their learning styles and preferences. ChatGPT also poses some challenges and limitations that can be considered a bane. While ChatGPT can provide vast amounts of information, it may not always be accurate or reliable. The responses produced by ChatGPT are also based on patterns and trends in the data it has been trained on, so they might not always offer a thorough or nuanced knowledge of a specific medical idea or situation. Consequently, it is crucial to make sure that medical students and researchers are aware of ChatGPT's limitations and use it in addition to rather than as a substitute for conventional learning and research techniques. All things considered, ChatGPT has the potential to be a useful tool in medical research and education, but it must be used carefully and with awareness of its limitations. This review article focuses on whether ChatGPT in medical education and research is a boon or a bane.

As shown in this present study, patients with posttraumatic osteoarthritis are prone to nerve injuries after total ankle arthroplasty and showed low level of patient satisfaction and poor clinical outcomes. Therefore, surgery should be performed with care to avoid any nerve injuries.

When observing the stress distributions on the screws, this study found that the two screws near the middle of the miniplate experienced higher stress than did the other screws, likely because the miniplate was being pulled to the screw that provided fixation of the mandible under the external bending and torsion forces. Thus, the two screws close to the middle of the miniplate experienced higher stress, especially the screw which is near the bone gap to the proximal segment (number 2 or 7). These findings suggest that clinicians should pay careful attention to the high stress that may be placed on the screw during miniplate fixation. Further, to achieve overall postimplant stability, a thicker screw should be used or the strength of the miniplate at that site should be enhanced.

Sagittal and transverse discrepancies often coexist in skeletal class II malocclusions. Orthopedic growth modification can work well in such cases, provided that the remaining pubertal growth is adequate and that the clinician can provide timely treatment to coincide with the peak growth period.

All participants were requested to brush their teeth after breakfast and before bedtime with a pea-sized quantity of fluoride toothpaste. Additional brushing or water irrigation after the midday meal was also recommended but was not an essential requirement of the study. On each day of the first, fifth and ninth weeks of the study, the patients were required to rinse their mouths with 5 cm3 of the antibacterial mouthwash for one minute after their evening brushing session. The patients were also requested to chew two pieces of xylitol gum for five minutes four times per day (preferably after snacks) throughout the 12-week period. The control group received no further treatment or intervention.

It has been largely documented that the carefully planned maxillary and mandibular positions can be accurately transferred to the patient at the time of the surgery using CAD/CAM guides. A preliminary study published by our group showed that the surgical template technique could provide a reliable method of planning transfer for segmental genioplasty. To date, there were only a few studies with small sample sizes on the use of genioplasty templates. However, the technique and the accuracy of transferring planned genioplasty at the time of the surgery still remained uncertain.

Results of this study suggest potential avenues for interventions to increase adherence to CPAP, including the provision of information and continued support. Individual counseling providing strategies aimed at helping the person to cope with the emotional problem and relational difficulties associated with the use of CPAP, and at strengthening self-efficacy and self-management skills are also encouraged for optimal care during the rehabilitation program.

The mechanism of referred pain was quoted in 1946 , stating that the association of nasal and intraorbital sensitive fibers and their nuclei at the central level explained the similarity of the symptoms of the pathological involvement of both areas, showing that the orbital pain may be produced in intra-nasal regions. Afferent fibers of pain receptors located in the nasal and paranasal mucosa determine the same pool of sensorial neurons in the nucleus of the trigeminal nerve than fibers coming from skin receptors. These two pathways end up in the same neurons of the common cortical area. “The cortical center can not differentiate the original peripheral source of impulses in this common pathway, thus, when the mucosa is stimulated, pain afferent impulses are falsely located after they reach the sensorial cortex. They are poorly interpreted and based in previous experienced such as coming from the skin, region from where the impulses normally reach this point in the brain” . Another mechanism of referred pain considers that the presence of neurogenic edema in distant regions of the stimulated site: trigeminal fibers that contain substance P, upon stimulation, can trigger antidromic impulses responsible for the release of substance P in other areas innervated by the trigeminal branches, which leads to an inflammatory process in these sites, explaining the onset of pain in the distant region of the stimulated area 14.

In the early stages, clear aligners were only considered to treat simple orthodontic problems of mild or moderate anterior crowding. With the development of computer technology and the gradual recognition of the biomechanical properties of aligner materials, CAT has demonstrated the capacity to treat more complex cases, such as cases requiring tooth extraction. Nevertheless, these case reports pointed out the limitations of using clear aligners to complete the gap closure in extraction treatment. Clear aligners are not rigid enough to retain their original shape in space closure, which might result in torque loss and adverse extrusion of the anterior teeth. Therefore, a certain amount of intrusion is intentionally added during the setup when the incisors are designed to be retracted. However, the effectiveness of extra intrusion in controlling the movement of incisors has not been proven, and the most efficient ratio between the amount of retraction and intrusion is unclear.

It is of critical importance that model surgery is based on accurate translation of the theoretical transposition data. Any discrepancy between the plan and the model surgery will lead to an inaccurate interocclusal splint. A poorly designed and/or fabricated wafer can lead to a disastrous outcome even when the most skillful surgical technique is used.

The diameter of the selected miniscrew will be determined by the MD length of available bone. It has been suggested that skeletal anchoring of the miniscrews is stable when they have a diameter between 1.5 and 2.3 mm7. The MD distance is highly relevant, given that one of the greatest risks for miniscrew failure is its proximity to the teeth roots. In the DS group, the intermolar area presented a longer MD distance, and the amount of available MD bone was greater than in the control group, probably because the teeth of the DS group were smaller than those of the control group. Microdontia is not uncommon among patients with DS and can result in spacing. In the general population, the intermolar area is also considered one of the most reachable locations for miniscrew placement because it has a larger space between the tooth roots. A number of authors have indicated that the longest MD distance in the maxilla is on the palatal side between the second premolar and first molar.

There are some limitations in this study. As portable sleep apnea testing was used to determine the preoperative sleep parameters, we were unable to determine the arousal index and other parameters, which would give precise insight into the phenotypes of surgical patients with unrecognized OSA in their response to oxygen therapy. Portable sleep apnea testing and overnight oximetry did not monitor electroencephalography, and we did not know whether patients were asleep when data were collected. Wakefulness during the sleep apnea testing and overnight oximetry may result in underestimation of AHI and ODI, and the severity of sleep apnea. Patients’ response to oxygen therapy is a new field in personalized medicine and our post-hoc analyses may be construed as hypothesis generating.

The integration and incorporation of AI and web search capabilities are rapidly being established. Free AI web-assistant tools such as Monica and HARPA AI have been developed to streamline the process of web browsing. These tools integrate ChatGPT into the web browsing sidebar, providing users with summaries of webpages in a simplified format after conducting an initial Google search. Although these tools enhance efficiency and enable users to access a larger volume of information in less time, the ability of ChatGPT to evaluate the readability and quality of medical text and detect biases remains uncertain. Evaluating the ability of ChatGPT to determine the quality of online medical content is currently imperative and will become increasingly important, as patients increasingly rely on the internet and social media for medical information.

In an attempt to further investigate what was occurring with the various liners, a simple additional experiment was conducted. The experiment consisted of placing one coat of polyamide varnish, two coats of copal varnish and five coats of dentin adhesive onto separate glass slides. A drop of 2 % HBF4 was placed onto each of these slides. The adhesive was rapidly dislodged and disrupted from the slide while the two varnishes remained intact. This supplemental experiment helped confirm what was observed in the tooth samples.

Orthodontic brackets designed for compensation of mild Class III malocclusions appear to be more efficient than non-compensated straight-wire prescription brackets. Treatment time for Class III patients treated with brackets designed for compensation was shorter than with Roth prescription and no difference in the quality of the occlusal outcome was observed. A prospective randomized study is suggested to provide a deeper look into this subject.

For the treatment protocol, each subject was instructed to wear aligners for 22 h per day, except during meals and oral hygiene procedures and to replace aligners on average every 15 days. Every 6 stages the clinician checked the good aligner fitting and the position of the attachments. The mean number of aligners was 25 for the maxillary arch and 24 for the mandibular arch. Both arches averaged 8 attachments and less than 2.5 mm of IPR in the upper arch and less than 4.5 mm of IPR in the lower arch.

Sleep plays a vital role in good health and well being throughout the life. Many people experience trouble in sleeping which may be because of stress or other factors and is usually temporary, but becomes a concern when it occurs repeatedly thus indicating a sleep disorder. Sleep disorders like bruxism and obstructive sleep apnea (OSA) are of great concern to the dentist. Dental sleep medicine is an emerging branch which deals with these sleep disorders by providing treatment with oral appliances.

In the current study, it can be concluded that postoperative bleeding events occur significantly more frequently in patients with anticoagulation therapy than in healthy patients, but the quality of bleeding shows significantly lower severity, even when a significant correlation with high-risk surgical interventions exists. It therefore appears reasonable to continue anticoagulation therapy perioperatively for small procedures and also the classified high-risk procedures within this study. Close interdisciplinary collaboration between oral surgeons and other medical specialists remains essential to minimise perioperative risks to patients, and the perioperative instruction of patients is crucial. Follow-up studies should include larger patient cohorts and investigate postoperative bleeding and its intensity under uniform risk classifications of surgical interventions.

The infraorbital nerve (ION) is another cranial nerve that may be exposed to injury during orthognathic surgery procedures. Thygesen et al. found that subjective changes in somatosensory function after LeFort I osteotomy occurred in 7 to 60 % of patients, depending on the site of measurement at 12-month follow-up [44]. Changes in cutaneous, mucosal, and pulpal thresholds occurred as a result of LeFort I osteotomy, and significant side effects such as cutaneous numbness and hypersensitivity, as well as intraoral numbness in the facial and palatal gingiva, are associated with that procedure [44]. Furthermore, segmentation of the maxilla additionally decreased sensory function in the palate and gingiva [44]. Despite these sensory problems, many patients were satisfied with their surgical results and would recommend the surgery procedure to other patients needing a combined orthodontic surgical treatment [44].

MCQ construction (including clinical vignettes) was the most common way ChatGPT was used. We note that the school has recently introduced low-stakes summative quizzes based on MCQs written by the faculty themselves, rather than sourced externally. Summative question construction has been a time-consuming and ongoing task for most faculty and may have influenced the number of faculty who reported using ChatGPT for this purpose. Whether this will continue to be a large fraction of ChatGPT usage will depend on whether our question bank becomes sufficient and if no further questions are needed.

In our cohort of OSA patients with RHTN, long-term CPAP use was associated with significant weight loss. Additionally, we noted an improved heart rate and a lower prevalence of arrhythmias in the group of patients compliant to CPAP therapy. Despite the positive effect on body weight and cardiovascular parameters, it is vital that CPAP treatment is accompanied by strong dietary interventions. Future prospective studies focusing on CPAP adherence in high cardiovascular risk patients with OSA may help to evaluate the effect of specific treatment in reducing cardiovascular risk.

The Thurow appliance was developed to apply distal and vertical forces while controlling molar rotation and tipping produced by forces directed through buccal molar tubes. The original appliance, which incorporates a high-pull headgear and a maxillary acrylic splint that serves as a bite block, has been shown to restrain maxillary growth, distally tip and displace the maxillary teeth, as well as restrain the eruption of posterior maxillary teeth. Because the splint precisely covers the entire maxillary dentition, higher force levels dissipating over a larger surface area can be used. The acrylic smooth surface disoccludes the teeth and effectively eliminates occlusal interferences during force application, which facilitates maxillary tooth movement and allows the mandible to grow unimpeded by the maxilla. The Thurow appliance is thought to be particularly well suited for Class II patients with maxillary prognathism, steep mandibular plane angles and open bites.

Besides being used for diagnostic purposes, PSG was also used to quantify the apnea severity of the patients. Mild apnea was considered when there was and AHI equal to or higher than 1 event per hour up to an index lower than 5 events per hour. An AHI higher than 5 events per hour up to an index lower than or equal to 10 events per hour characterizes apnea as moderate. Severe apnea was considered in the presence of an AHI greater than 10 events per hour.

Orthodontic treatment is performed for correction of dental irregularities. Archwires generate the force required for orthodontic tooth movement. Selection of an appropriate archwire in fixed orthodontic treatment for load application to the teeth can contribute to treatment success. Initial archwires are used at the onset of fixed orthodontic treatment, and are mainly used for correction of crowding and slight tooth rotation. Light continuous force is ideal for orthodontic treatment since it would result in controlled and predictable tooth movement with minimal damage to the teeth and their supporting structures. Clinically, efficient force should cause maximum tooth movement with minimum root resorption and pain [1].
