Objective: The objective was to study the effect of orthodontic therapy regarding the position of the hyoid bone and upper airways in nighty-one 6-21 year-old Caucasian patients with normoclussion.

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.

Objectives: This study assessed the voice quality in TMD patients compared to healthy individuals using the Dysphonia Severity Index (DSI) and evaluated the correlation between the DSI and TMD severity.

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 (p < .001). A significant correlation was found between the DSI scores and TMD severity (Spearman's rho: -0.90, p < .001).

Conclusion: Patients with TMD demonstrated lower DSI scores and lower voice quality compared to healthy subjects.

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.

Objective: To assess jaw and neck function, pressure pain threshold (PPT), and the presence of trigger points (TrPs) in disc displacement with reduction (DDWR) subjects compared to healthy subjects.

Methods: One hundred DDWR subjects and 100 matched controls were studied. Clinical evaluations included demographic data, range of motion, jaw and neck disability, PPT, and muscle TrPs.

Results: DDWR subjects have limited pain-free opening limitation (p < 0.001), jaw and neck disability limitation (p < 0.001), and higher presence of active and latent TrPs limitation (p < 0.001) compared to healthy subjects.

Conclusion: DDWR subjects present a limited pain-free mouth opening, higher jaw and neck disability, lower PPT, and major presence of active and latent TrPs compared to healthy subjects. Cervical spine and TMJ evaluation and treatment should be considered in DDWR patients.

Objective: To discover the extent of the connection between occlusal plane asymmetry and the rest tone of the four muscle groups of the orofacial region with temporomandibular joint pathology.Methods: Eighty-seven subjects were divided into two groups. The following methods were applied: clinical examination, roentgenological examination, and electromyography. Data were evaluated and statistically analyzed.Results: The variability of occlusal plane inclination in relation to the porion plane was 0-4.6º.The tonus of masseter muscle was higher in the experimental group: 1.45 mV more than in the control group: 1.23 mV (p < 0.05).Conclusion: Asymmetry of the occlusal plane inclination was found for nearly all subjects in both groups. It can be compensated for by adaptation mechanisms and does not cause temporomandibular joint disorders. Undertaken research shows the existence of a proven correlation between TMJ disorders and the resting tonus of the masseter muscle.

Objective: To obtain a current overview of the use of mandibular advancement splints (MAS) as a therapeutic option for obstructive sleep apnea (OSA) in the dental profession in Northern Germany.

Methods: A questionnaire was mailed to 2431 dental professionals, and 8.3% responded. Descriptive data analysis was performed on each question separately.

Results: Most of the surveyed dentists (51.7%) estimated the success rate of MAS therapy to be higher than 75%. Analysis of the relationship between the number of splints prescribed annually and the dental specialization (p = 0.22), work experience (p = 0.14), estimated success rate of MAS therapy (p = 0.96), and discontinuation of MAS therapy (p = 0.57) revealed no significant correlations.

Conclusion: Mandibular advancement splints seem to be a safe and successful therapy for OSA. There seems to be a lack of information on the patient side and a lack of education on the dentist side.

Objective: The aim of this study was to assess the association between the symptoms of temporomandibular disorder (TMD), sleep quality, and indicators of burnout syndrome in teachers.

Methods: This cross-sectional study included 330 teachers with an average age of 43 years. The Diagnostic Criteria for Temporomandibular Disorders, Pittsburgh Sleep Quality Index, and the questionnaire to assess burnout syndrome - teachers' version were used for data collection. Simple and multiple logistic regression models were applied to analyze the independent variables at a 5% significance level.

Results: Teachers with poor sleep quality, indicators of burnout syndrome, female sex, and impact on the domains of psychological exhaustion and guilt were, respectively, 1.91,1.92, 2.66, 1.97, and 2.60 times more likely to present at least one TMD symptom (p < 0.05).

Conclusion: Teachers with indicators of burnout syndrome and impaired sleep quality were more likely to present with at least one TMD symptom.

Objective: To evaluate reliable and validated temporomandibular disorder (TMD) diagnostic instruments for use as diagnostic tools in epidemiological surveys.Methods: Two independent reviewers performed searches in the Medline/PubMed, Cochrane Library, and Web of Science databases to identify validation studies of diagnostic and screening instruments for TMD published up to March 2021.Results: Sixteen studies were included for the systematic review. Different TMD instruments were evaluated, such as FAI, RDC/TMD, DC/TMD, Helkimo Index, and AAOP Questionnaire. The instruments differed according to the number of items. Some questionnaires appear to be effective for the initial screening of TMD patients and can be incorporated in clinical practice and epidemiological studies since they are easy and fast to apply.Conclusion: To provide an accurate TMD diagnosis, it is important to use instruments that involve a clinical examination. Authors suggest the development of a new validated diagnostic tool for use in epidemiological surveys.

Objective: This study investigated the associations between temporomandibular disorder (TMD) symptoms, psychological distress, and well-being.

Methods: A total of 372 university students were recruited and stratified into no TMD, TMD pain, TMJ sounds, and combined TMD groups. Psychological distress and well-being were assessed with the Depression, Anxiety, and Stress Scale-21 (DASS-21) and Scales of Psychological Well-being-18 (SPWB-18), respectively. Data were appraised with Kruskal-Wallis/Mann-Whitney U tests and logistic regression analysis (α = 0.05).

Results: Significant differences in anxiety, stress, and autonomy scores were observed among the four groups, and psychological distress was mostly negatively correlated to psychological well-being. Multivariate analyses revealed that anxiety was associated with TMD pain, TMJ sounds, and combined TMD, while autonomy was related to TMJ sounds.

Conclusion: Participants with TMD symptoms generally experienced more psychological distress and lower autonomy. Anxiety appeared to increase the likelihood of TMD pain and/or TMJ sounds.
