METHODS: Nineteen variables were analyzed by teleradiography. The differences were analyzed with the ANOVA test of repeated measures with an intra-group factor for two occasions. RESULTS: The statistical analysis revealed a greater influence on the variables Hy-MP (12.3 vs 14.2), Hps-C3 (25.2 vs 28.1), Hpi-C3 (28.8 vs 35.5), H°-C3 (14.4 vs 12.7), Hps-Rg (36.0 vs 42.7), Hpi-Rg (34.1 vs 39.7), USP (16.2 vs 20.2), MPP (12.9 vs 14.8), C3P (10.6 vs 12.8), PNS-Ba (43.5 vs 66.5), PtV-Ad (12.0 vs 17.1) and PtM-Ba (33.9 vs 35.9), and Ad2-SO (24.16 vs 20.87). DISCUSSION: Significant differences were observed between most of the airway and hyoid bone variables before and after orthodontic treatment in our Spanish pediatric population, especially in the nasopharynx.

METHODS: Patients who had TMD with Fonseca's anamnestic index were subjected to an examination based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). A sample of 35 patients with TMD and 36 healthy subjects were included in the study. RESULTS: There were significant differences in the DSI score and its components between healthy subjects and TMD patients ( < .001). A significant correlation was found between the DSI scores and TMD severity (Spearman's rho: -0.90, < .001). CONCLUSION: Patients with TMD demonstrated lower DSI scores and lower voice quality compared to healthy subjects.

METHOD...OBJECTIVE: This systematic review aimed to evaluate the effectiveness of conservative approaches on otologic signs and symptoms in patients affected by Menière's Disease (MD) and temporomandibular disorders (TMD). METHODS: PubMed, Scopus, and Web of Science were systematically searched to identify studies presenting participants with a diagnosis of MD associated with TMD, conservative approaches as interventions, and modification of the otological signs and symptoms as outcome. RESULTS: Out of 627 articles assessed for eligibility, two studies were included. Both studies showed a significant reduction of Situational Vertigo Questionnaire after treatment, number of vertigo spells, Functional Level Scale, Dizziness Hearing Inventory, and Tinnitus Handicap Inventory, after occlusal splint therapy. No significant differences were found in terms of pure-tone audiometry average. CONCLUSION: Findings of this systematic review suggested that conservative approaches might improve vertigo in patients affected by MD and TMD. However, the low number of included studies makes difficult to draw strong conclusions.

METHODS:...OBJECTIVE: This study aimed to determine the diagnostic value of ultrasonography (US) in internal derangements of temporomandibular joint (TMJ) and to compare its efficacy with magnetic resonance imaging (MRI). METHODS: Fifty patients with MRI indications due to a TMJ disorder were enrolled. Findings of the clinical examination, US examination and MRI examination were noted by seperate clinicians and the sensitivity, specificity and diagnostic accuracies of all examinations were compared. RESULTS: When compared with MRI, the sensitivity, specificity and diagnostic accuracy of the clinical examination for the internal derangements were 73%, 37%, and 70%, respectively and 75.7%, 33.3% and 73.0% for US examination, respectively. CONCLUSION: US can be considered as an alternative to MRI as it can be used to detect the disc position, internal derangements, intraarticular fluid accumulations and superficial condyle changes with minimally better results than clinical examination.

METHODS: The GSQ underwent evaluation for face and content validity. Participants were selected via convenience sampling from five healthcare centers. Sociodemographic variables, including gender, number of children, recreational activities, budget deficits, and family conflicts were analyzed. Confirmatory factor analysis was conducted to verify the results. Internal consistency was assessed using Cronbach's α, and test-retest reliability was evaluated using the intraclass correlation coefficient (ICC). RESULTS: 200 older adults (mean age 66.8 years) completed the questionnaires. Face and content validity were confirmed by 30 experts (S-CVI/average = 0.96). The final model exhibited good fit indices (χ2/df = 2.89, CFI = 0.96). The scale demonstrated acceptable internal consistency (α = 0.81) and test-retest reliability (ICC = 0.98). CONCLUSION: The Persian GSQ demonstrates high reliability and validity for assessing sleep quality in older adults, aiding research in this field.

METHODS: A survey consisting of two validated questionnaires was distributed to dental patients registered at the University of Malaya Faculty of Dentistry. The Fonseca Anamnestic Index (FAI) evaluates the prevalence and severity of TMD, while the Oral Health Impact Profile - Temporomandibular Disorder (OHIP-TMD) appraises the effects of TMD on oral health-related QoL. RESULTS: Out of 342 patients (aged 16 to 50 years, 45% male and 55% female) enrolled in the survey, 50.9% had varying degrees of TMD. All 7 domains of OHIP-TMD showed a statistically significant correlation with TMD severity. CONCLUSION: TMD seems to be prevalent among Malaysian dental patients. Not only does TMD affect the QoL of an individual, but the more severe the degree of reported symptoms, the poorer their perceived oral health QoL.

METHODS: Representative samples of older adults (≥60 years) were included ( = 569). Both TMD symptoms and OHRQoL were assessed by Fonseca Anamnestic Index (FAI) and Oral Health Impact Profile-14 (OHIP-14), respectively. Prevalence (those answering "frequently" or "always" in at least one question), severity (total means scores), and extent (number of questions answered as "frequently" or "always") of OHRQoL were estimated. RESULTS: Overall, 33.4% and 9.5% had mild or moderate/severe TMD symptoms. Those with any symptom of TMD had a prevalence ratio (PR) 38% higher for the worst OHRQoL (95% confidence interval [95%CI]:1.04-1.82) compared to those without TMD symptoms. Worst OHRQoL were observed for those with mild (PR:1.35; 95%CI:1.01-1.81) and moderate/severe TMD (PR:1.53; 95%CI:1.04-2.26). Similar results were detected in the severity and extent of OHRQoL. CONCLUSION: Severity TMD was associated with worse ORHQoL.

METHODS: A specific questionnaire consisting of 20 questions, including 10 questions on improvements and 10 on side effects, was developed and mailed to all subjects (54). RESULTS: 42 patients, participated in the survey by answering the questionnaire. The results showed that patients placed greater importance on the positive outcomes of treatment, with the most significant being the reduction in snoring and improvement in sleep quality. On the other hand, the side effects of difficulty speaking with the device, tooth mobility, and foreign body sensation were considered important. CONCLUSIONS: The advantages perceived by the patients appear to outweigh the disadvantages, especially the reduction of snoring, increased productivity, and improved social and intellectual life. Most significant side effects are reversible and short-term, while occlusal changes, is not considered important by patients.

METHODS: This systematic review with meta-analysis compared the prevalence and scores of depression between TMD groups and controls. RESULTS: The results showed that depression was a significant risk factor in the development of RDC/TMD axis I muscle disorders (group I) and arthralgia/osteoarthritis/osteoarthrosis (group III), and non-significant for disc displacements (group II). Severe depression had almost four times the risk of developing TMD as compared to moderate depression. CONCLUSION: These findings suggest that addressing psychological factors in general, and depression in particular, in the managemenof TMD is crucial, especially in those TMD groups with higher pain levels (I and III), and the TMD pain reduction is crucial in reducing depression levels.

A digital questionnaire was sent to the member of the National Swedish EDS Association during January-March 2022. The subsamples of hypermobile and classical EDS were constructed. Almost 90% reported TMD symptoms. Bite splint therapy, counselling, jaw training and occlusal adjustment were reported as the most common treatments with no statistically significant difference in terms of good effect between the two subsamples. Hypermobile and classical EDS might consider as an entity with regards to TMD.

METHODS: TMD/somatic symptoms were appraised with the five quintessential symptoms (5Ts) of the DC/TMD/Somatic Symptom Scale-8, whereas mental distress/well-being was assessed with the Depression, Anxiety, Stress Scales-21/Scales of Psychological Well-being-18. Data were examined using Chi-square/non-parametric tests and multivariate analyses (α = .05). RESULTS: Among the 366 participants, 51.4%, 28.1%, 6.8%, and 13.7% had no TMD (NT), TMD pain (TP), TMD dysfunction (TD), and combined TMD (CT) respectively. Though mental distress varied substantially (CT, TP>NT, TD), no significant differences in well-being were discerned. SS burden, but not TS burden, was moderately correlated to distress. CONCLUSIONS: The prospect of TMD pain was increased by being female, depressed, and anxious but reduced by "positive relations with others" and "self-acceptance".

SUBJECTS AND METHODS: TMD patients from two University-based centers in China and South Korea were enrolled. Axis I physical diagnoses were rendered according to DC/TMD. Patients were categorized into six age groups (15-24, 25-34, 35-44, 45-54, 55-64, and 65-84 years; Groups A-F respectively). RESULTS: Youths/young adults (Groups A-C) formed 74.1% of TMD patients. TMJ disc displacements (74.9%), arthralgia (49.2%), and degenerative joint disease [DJD] (36.8%) were the most common TMD subtypes. The majority had combined (54.0%) and chronic (58.5%) TMDs. Youths/young adults and middle-aged/old adults had substantially lower frequencies of merely pain-related (6.2-14.5%) and intra-articular (13.8-16.8%) TMDs correspondingly. "Being female" increased the prospects of pain-related/combined TMDs by 96%/49%, respectively. CONCLUSIONS: East Asian TMD patients comprised mostly of youths/young adults who had an alarmingly high prevalence of TMJ DJD.

Electro neuromodulation techniques have been in use for many years as promising methods of therapy for cognitive and emotional disorders. One of the most widely used forms of stimulation for orofacial pain is transcutaneous trigeminal stimulation on three levels: supraorbital area, dorsal surface of the tongue, and anterior skin area of the tragus. The purpose of this review is to trigger interest on using dental ULFTENS as an additional trigeminal neurostimulation and neuromodulation technique in the context of TMD. In particular, we point out the possibility of using ULFTENS at a lower activation level than that required to trigger a muscle contraction that is capable of triggering effects at the level of the autonomic nervous system, with extreme ease of execution and few side effects.

METHODS: A cross-sectional, analytical observational study was carried out during 2021-2022. Two hundred and ten orthodontists and pediatric dentists were surveyed using the adapted and validated Spanish translation of the OSAKA-KIDS questionnaire and additional sociodemographic questions. RESULTS: The data indicated an association between dental specialty and the professional's knowledge about POSA. Orthodontists were 59% less likely to have acceptable knowledge, compared to pediatric dentists ( = .013, IC 95% 0.21-0.83). The study revealed an association between the professional's attitudes and three intervening variables: age ( = .025), clinical experience ( = .049) and sector of practice ( = .020). CONCLUSION: Knowledge was associated with the dental specialty of professionals in the sample included, whilst attitudes were not.

There is variation in the frequency and distribution of complaints in children about this disorder. MATERIALS AND METHODS: This study was conducted on 407 children aged 5-18 years. Patients with dentofacial function problems, trauma, history of surgery, and malignancy were excluded from the study. Patients with temporomandibular magnetic resonance imaging in their records were classified as normal, reduction disc displacement and non-reduction disc displacement. RESULTS: Patients symptoms were click (77.2%), pain (71.5%), headache (61.2%), bruxism (31.9%), locking (28%), difficulty in mouth opening (24.3%). The most common clinical findings are normal mouth opening (62.2%) and deviation (44.9%). When the MR results were examined, 55.1% of female and 66.6% of male were observed to be normal, and this statistically shows that males have more normal MR findings. CONCLUSION: TMD are also observed in children. Clinical history and findings are helpful in diagnosis, but the contribution of imaging methods may be limited. If head and neck pain is detected in children, TMD should be kept in mind.

METHODS: Ninety-seven adult OSA patients underwent polysomnography and cone beam computed tomography (CBCT). The anatomical and aerodynamic characteristics were measured based on CBCT images and computational fluid dynamics modelling of the upper airway. RESULTS: After controlling for patients' gender, age, and body mass index (BMI), the maximum velocity during inspiration (In-Vmax) led to the largest increase in the explanatory power of apnea-hypopnea index (AHI) variation. The In-Vmax was closely correlated with the minimum axial area, and their relationship was represented by an inversely proportional fitted curve. CONCLUSIONS: The In-Vmax was the most relevant to OSA severity, and it could be used to assist in recognizing severe OSA patients and as a primary variable to evaluate treatment outcomes of OSA. The In-Vmax was closely related to the most constricted area of the upper airway.

METHODS: Data included 165 juveniles diagnosed with ASD, allocated to younger group aged 6 21 (n=86) and older group aged 13-21 (n=79). RESULTS: Sleep bruxism was reported by 26.7% in the younger group and by 5% in the older group. Awake bruxism was reported by 22% and 17.7%, respectively. Oral habits were reported by 43% of all participants, with similar rate in both groups. TMD related p ain was low in both groups (6.3% and 7% respectively). The influence of the COVID 19 pandemic on oral parafunction was moderate in the younger group (17.4%) and mild in the older group (8.6%), influence on bruxism was mild in both groups (5.8% and 2.5%, respectively). CONCLUSION: The prevalence of bruxism and oral parafunctions was similar to the reported in the literature for the general population.

A total of 6365 people from 11 studies were included. Sample mean age ranged from 12 to 69.5 years. The pooled prevalence of TMD was 33.6% (95% CI 31.5-35.8; I = 37.2). Prevalence of TMD was higher in females (37.0%) than in males (29.3%). Our results indicate that TMD is a prevalent condition across Brazil's territories. The results from this meta-analysis can help calculate more accurate sample sizes for future studies.
