Objetivo: Apresentar dois casos de pacientes portadores de DTM com significativa instabilidade oclusal. Relato de casos: caso 1 - gênero feminino, 16 anos, dentada; caso 2 - gênero feminino, 60 anos, portadora de próteses. Ambas as pacientes, quando manipuladas, apresentavam grande diferença da máxima intercuspidação habitual para a relação cêntrica. O tratamento proposto para os casos foi o uso de placa estabilizadora. Conclusão: A placa estabilizadora acarretou bons resultados, havendo remissão total dos sintomas.

Cervical dentin hypersensitivity (CDH) is defined as an acute pain of short duration that occurs in dentin exposed to the oral environment. The aim of this study was to evaluate the effi cacy of three desensitizing toothpastes (Sensodyne® Rapid-Relief, Colgate® Sensitive Pro-Relief, Nano P®) for immediate and intermediate-term relief of CDH, when compared with a control toothpaste (Cocoricó®). Eight patients were enrolled in this clinical study. One hundred thirty-eight hypersensitive teeth were randomized into four groups according to the com- position of the desensitizing toothpaste tested: Group I) strontium acetate and calcium carbonate; II) calcium carbonate and arginine 8%; III) calcium phosphate nanoparticles; and IV) a control toothpaste. A split mouth design was used for one application each of the desensitizing dentifrices. Assessment of CDH was done by evaporative and cold stimuli at baseline, immediately, 24 hours and 30 days after the treatment. The toothpastes presented similar effectiveness and statistically significant improvement in 30 days compared to baseline. Group III showed statistically significant relief for cervical dentin hypersensitivity immediately after the treatment. The only toothpaste that presented immediate relief effect was the paste containing calcium phosphate nanoparticles in the form of hydroxyapatite.

Aim: The aim of this study was to report a retrospective study on the profile of patients seen in the last 11 years [2004–2014], in a TMD clinic at the Federal University of the Jequitinhonha and Mucuri Valleys. Methods: All medical records were evaluated from January 2004 to December 2014. The following items of information were collected: gender, age, parafunctional habits, main complaints and treatment offered. The data collected were analyzed by using SPSS 22.0 software. Results: A total of 560 patient records related to 448 [80%] women and 112 [20%] men were evaluated. The age ranged from 10 to 93 years. Etiologic factors were reported in 374 [66.8%] records. There was an association between age and abuse [p = 0.003]. There was no significant association between treatment and gender [p = 0.361]. Conclusion: The profile of TMD patients seen in the last decade [2004–2014] was characterized by the majority being female patients, mean age 34.94 years and having some parafunctional habit.
