Counselling treatment versus counselling associated with jaw exercises in patients with disc displacement with reduction-a single-blinded, randomized, controlled clinical trial.

OBJECTIVE: To compare effectiveness of counselling program versus counselling program plus jaw exercises to reduce pain and click in patients with temporomandibular joint disc displacement with reduction (DDWR). MATERIALS AND METHODS: Patients were divided into two groups: instructions for temporomandibular disorders (TMD) plus jaw exercises (test, n = 34), only TMD instructions (control, n = 34). Pain was analyzed by palpation (RDC/TMD). It was investigated if the click caused discomfort. Both groups were evaluated at baseline, 24 h, 7 days, and 30 days' post treatment. RESULTS: The click was present in 85.7% (n = 60). In 30-day evaluation, there was a statistically significant difference between groups in the right median temporal muscle (p = 0.041); and there was a statistically significant difference in treatment self-perception (p = 0.002) and click's discomfort (p < 0.001). CONCLUSION: The exercise with recommendations showed better results, resolution of the click, and self-perception of the treatment effectiveness. CLINICAL RELEVANCE: This study presents therapeutic approaches that are easy to perform and that can be monitored remotely. In view of the current stage of the global pandemic, these treatment options become even more valid and useful. CLINICAL TRIAL REGISTER: This clinical trial was registered at Brazilian Clinical Trials Registry (ReBec) under protocol RBR-7t6ycp ( http://www.ensaiosclinicos.gov.br/rg/RBR-7t6ycp/ ), Date of registration: 26/06/2020.

Oral health-related quality of life in patients with disc displacement with reduction after counselling treatment versus counselling associated with jaw exercises.

OBJECTIVE: The aim of this study was to compare the effectiveness of two types of treatment (counselling programme versus counselling programme plus jaw exercises) to improve the quality of life of patients with disc displacement with reduction (DDWR). MATERIALS AND METHODS: Patients were divided into two groups. The test group received guidelines for temporomandibular disorders (TMD) plus jaw exercises for DDWR, and the control group received only guidelines for TMD. The total number of investigated patients was 70, thus 35 per group. The oral health-related quality of life was assessed by the OHIP-14 questionnaire. Both groups were evaluated at the baseline and 30 days post-treatment. RESULTS: In the counselling group, there was statistically significant decrease in pain (P = .015) and social disability (P = .046) subscales. In the counselling plus jaw exercise group, there was statistically significant decrease in all subscales (P < .05). At 30 days follow-up, there was a statically significant difference between the two groups in pain (P = .004), psychological discomfort (P < .001), psychological disability (P < .001) and social disability (P = .029) subscales. CONCLUSION: The counselling programme plus jaw exercise protocol showed greater improvement in oral health-related quality of life than the group performing only the counselling programme in patients with DDWR.
