Objective: To assess the prevalence of temporomandibular disorder (TMD)-related pain, anxiety, and depression among military police officers from Niteroi, Rio de Janeiro, Brazil, and to compare these outcomes with a civilian population. Methods: This cross-sectional study included 84 police officers treated at the Dental Service of the Military Police Hospital and 84 non-police officers treated at the School of Dentistry of Fluminense Federal University. Data were collected digitally using validated instruments: the TMD Pain Screener, the Symptom Questionnaire, and the Hospital Anxiety and Depression Scale. Statistical analyses were performed according to variable characteristics, with a significance level of 5%. Results: TMD-related pain was identified in 26.2% of police officers and 31.0% of civilians. No statistically significant differences were found between groups regarding anxiety or depression prevalence. In both groups, women showed a higher frequency of TMD symptoms (p < 0.05). Conclusion: Police officers and civilians showed similar TMD-related pain prevalence.

BACKGROUND AND OBJECTIVES: The use of orthodontic appliances is constantly associated with symptoms of temporomandibular disorder (TMD). In this sense, the present study aimed to investigate the development of TMD symptoms in patients undergoing orthodontic treatment with occlusal lifting. METHODS: This is a longitudinal, quantitative and descriptive study; 40 patients with an indication for orthodontic treatment, participating in the study. They were evaluated: before the start of orthodontic treatment (T0), 24 hours (T1) and 30 days (T2) after installation of the occlusal elevator. Symptom assessment was carried out by applying the DC/TMD symptom questionnaire. The assessment of psychosocial factors was carried out using the “WISE Clinicians” test (Web Based Interdisciplinary Symptom Evaluation). The data were entered into a Microsoft Excel spreadsheet for statistical analysis using the Chi-Square test, with a significance level of 5%. RESULTS: In the T1 assessment, 42.50% (n= 17) of patients reported feeling any type of pain and 57.50% (n= 23) did not feel any pain. At T2, the proportion of patients who reported pain was 30% (n= 12), while 70% (n= 28) did not show any symptoms; 10% (n=10) of patients reported pain at both times; 37.50% (n=15) did not experience pain at any time during the assessment; 32.50% (n=13) assessed pain at the first moment and after the second assessment they no longer expressed pain. CONCLUSION: It can be concluded that occlusal lifting was not significant in terms of pain in most patients and when compared to the control group.

Temporomandibular disorder (TMD) is a term that covers a number of clinical problems involving the masticatory muscles, TMJ and all associated structures leading to signs and symptoms such as jaw pain, otalgia, headaches and limitation of function. In this context, TMD has been related to facial type and there are three distinct facial types (euryprosopic, mesoprosopic, and leptoprosopic). Objective: The aim of this study was to investigate the correlation between myofascial pain and facial types classified by the RDC/TMD Axis I. Material and Methods: this study was composed of 64 women aged between 12 and 49 years, using data obtained from two institutions. We used the anthropometric methodology, which meets the criteria of simplicity and reliability. We also applied the Brugsh Facial Index. The individuals were classified as euryprosopic (51.56%), mesoprosopic (12.50%) and leptoprosopic (35.94%), without statistical significance among the groups (p=0,3492). Results: there is no statistical difference between the age groups (p=0.2976) and no association between facial type and age range. Conclusion: this study found that there was a correlation between myofascial pain and facial types, with the predominance of euryprosopic faced women aged between 20 and 29 years when compared with other facial types and other age groups.

Introduction. Considering oral rehabilitation with dental implants, many studies have aimed at improving bone regeneration through the use of biomaterials. Objective. This study aimed at comparing bone neoformation in patients undergoing bilateral maxillary sinus surgery with two bovine biomaterials. Materials and Methods. This is a randomized, blinded, clinical crossover, and divided mouth study. Ten participants with an indication of maxillary sinus enlargement were selected and underwent surgical treatment with Bio-Oss® graft biomaterial (graft 1) on one side and Lumina-Porous® graft biomaterial (graft 2) on the other. The samples were collected after nine months and fixed and then decalcified in 10% ethylenediamine tetra-acetic acid (EDTA) solution for 30 days to process and make histological slides. Connective and bone tissue were further analyzed to identify the amount of newly formed bone. Results. The graft 1 group had a greater formation of vital mineralized tissue when compared to the graft 2 group ( p = 0.01). For nonvital mineralized tissue and amount of connective tissue, there was no statistical difference ( p = 0.21 and p = 0.09, respectively). The medullary spaces were larger in the graft 2 group. The group treated with graft 1 presented a higher percentage of osteoclasts and viable osteocytes compared to the graft 2 group ( p = 0.014 and p = 0.027, respectively). Conclusion. Every day, new alternative biomaterials are offered as an option in oral rehabilitation. In this study, both treatments induced bone neoformation after 9 months; however, the group treated with Bio-Oss® showed a higher percentage of vital mineralized bone tissue.

BACKGROUND AND OBJECTIVES: The number of temporomandibular joint (TMJ) surgeries has been growing in recent years. The objective of this study was to evaluate the factors measured for the indication of TMJ surgery. METHODS: This is an observational, quantitative, retrospective, cross-sectional study. A total of 99 surgical requests for TMJ surgery, assigned to a supplementary health operator, were analyzed. Information regarding age, gender, the patients’ main complaint, movement alteration, magnetic resonance results, diagnostic tests used, and previous therapy performed were collected. The T-test and the Chi-squared test were used (α=5%). RESULTS: 85% of patients were female, and the mean age among women (27.07±6.33) was lower when compared to men (31.98±9.55) (p=0.03). Almost half of patients did not receive any therapeutic approach prior to the surgery indication. Less than 10% of the requests described the Wilkes classification. Among the symptoms considered for the indication of surgery. pain report in the TMJ region (63.64%) stands out. The clicking and mouth opening limitation were among the highest prevalence as 52.5% and 67.7%. respectively. CONCLUSION: The factors evaluated for the indication of TMJ surgery by oral and maxillofacial surgeons in the present study do not match the recommendations of the Colégio Brasileiro de Cirurgia e Traumatologia Buco-Maxilo-Facial (CTBMF – Brazilian College of Oral and Maxillofacial Surgery and Traumatology). Few conservative treatments were previously recommended. Where the majority was decided without any diagnostic criteria.
