Official Title: Efficiency of Two Occlusal Splints on TMD Treatment: Randomised Clinical Trial

Brief Summary: Stress is an important cause factor of temporomandibular disorder (TMD) and Police Officers are exposed to stress. Aim of the study was to evaluate clinical and electromyographically the effect of two different occlusal splints on police officers with TMD

Detailed Summary:

After the approval by the Human Research Ethics Committee of the Piracicaba Dental School by the register number 189/03, 905 police officers of the São Paulo State - Brazil filled up the Axis II of Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and 256 volunteers were selected with TMD symptoms. Afterward the volunteers were submitted to the Axis I of RDC (clinical examination) and were excluded who presented systemic diseases like fibromyalgia, arthritis, arthrosis or osteoporosis, historical of TMJ (temporomandibular joint) surgery or TMD treatment, dental prosthesis, loss of more than two posterior teeth (except third molars and teeth extracted for orthodontic reasons), incomplete dentition with spaces in the arch (except third molars),volunteers with orthodontic and/or orthopedic appliances, with mandible and/or maxilla fractures, vertebrae or medullar canal stenosis, taking anti-inflammatory, analgesic and/or muscle-relaxing drugs, in otologic treatment or without compromise with the investigation. Who presented myogenic or mixed TMD, TMJ pain for at least three months and joint tenderness on palpation on at least one side was invited to remain in the study.

According to the exclusion and inclusion criteria above presented were selected 30 volunteers (15 women and 15 men), average age of 29 years, with diagnosis indicative of myogenic or mixed TMD.

The volunteers were randomized divided into three different groups with 10 persons per group using a stratification method performed by computerized table that placed the subjects into different groups according to the occlusal splints. Group A: Not received any oral device (Control); Group B: Used Michigan Occlusal Splint (MOS);Group C: Used Planas Oral Appliance (POA).
