Objective: To assess the association between self-reported symptoms of pediatric OSA and clinical signs in MB children.

Methods: Seventy-three MB children aged 7-14 years answered an interview questionnaire on OSA symptoms in childhood, focusing on chewing, nasal, and sleep disturbances. MB children were checked for changes on the craniofacial, occlusion, TMJ, upper airway, and body posture by a multi-disciplinary team, consisting of medical residents, dental, and psychology postgraduate students. Multiple logistic regression analysis verified the association between clinical signs and self-reported symptoms.

Results: Reported symptoms of chewing disturbance as TMD noise, muscle pain, and morning headache were significantly associated with the presence of lip incompetence and Class II malocclusion. Sleep disturbances as snoring, waking up at night, daytime sleepiness, and sleeping with the mouth open were significantly associated with the presence of hypertrophic tonsils and obstructive Mallampati score.

Conclusion: Symptoms of pediatric OSA were found in mouth-breathing children, which should be carefully investigated in order to prevent OSA in the future.

Objectives: Anabolic androgenic steroids (AAS) are derivatives of testosterone, used to treat gonadal disturbances, performance enhancement, and aesthetic purposes. AAS abuse can lead to side effects, including androgenic, cardiovascular, and liver disturbances, effects on libido, gynecomastia, and behavioral effects. There is a hypothesis that some joint tissues may be targets for sex hormones, and the use of AAS without medical follow-up may exacerbate temporomandibular joint problems in patients seeking performance and aesthetics.

Methods: In this study, a cross-sectional survey was conducted on AAS abusers who voluntarily presented themselves for clinical evaluation. Patients were subdivided by sex and age group, and the length of AAS use and symptoms such as headache, tinnitus, and temporomandibular joint pain were evaluated.

Results: It was observed that drug usage is related to symptoms.

Conclusion: The results suggest that AAS use without medical follow-up may exacerbate temporomandibular joint problems, especially in patients with low estrogen levels.

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 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: 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: 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.
