About

This study aims to evaluate the effectiveness of counseling on pain, function and well-fare outcomes for the management of patients with temporomandibular disorder (TMD).

Full description

In this study, 51 patients were allocated to one of the research groups. In Group I, it was instituted counseling therapy. For Group II was conducted treatment as usual with occlusal splint. Patients were followed for returns at 7, 15, 30 and 60 days after baseline. At baseline, all patients were examined and assessed Research Diagnostic Criteria/Temporomandibular Disorder (RDC/TMD form). In addition, the patients were referred for specific treatment according to the group to which belonged. In each session, patients were also surveyed about pain intensity using a Numeric Scale. To analyze the impact of pain on quality of life, Oral Health Impact Profile (OHIP-14) questionnaire was used.

50 participants in 2 patient groups

Counseling Group

Experimental group

Description:

Patients allocated to the counseling group (Group I) were informed about possible etiological factors and educated to not overload the temporomandibular joint and masticatory muscles. Techniques to relieve pain and tension were taught to correct postural habits, food and sleep irregularities. The patients received written instructions, as a way of reinforcing the information provided during the initial consultation. In subsequent returns at 7, 15, 30 and 60 days of follow-up, the instructions were given again and patients were asked whether they had detected any habits related to the initiation and maintenance of painful symptoms of TMD, as a way to further highlight the association between the presence of these harmful behaviors and the worsening signs and symptoms of TMD.

Treatment:

Behavioral: Counseling

Splint Group

Active Comparator group

Description:

Patients allocated to the splint group (Group II) were treated using interocclusal appliances, according to the following protocol: At baseline, an anterior bite plate (front-plateau) was made from acrylic resin that was placed in the maxillary arch to include the the canine to canine region and promote the disocclusion of the posterior teeth. Patients were instructed to use the device for 24 hours, interspersed with rests of equal length during the first week. After 7 days, the device was removed. A hard splint was then made. At 30 days of follow-up, the splint was fitted and the patients were also asked to use it when they were sleeping.
