Summary

The purpose of this study is to evaluate the efficacy of combining low-level laser therapy and the self-management program for patients with temporomandibular joint disorders using a randomized controlled design.

Conditions

  • Temporomandibular Joint Disorders
  • Facial Pain

Interventions

BEHAVIORAL

Self-Management Program

Self-Management Program includes education about the disorder, proprioceptive awareness and reversing parafunctional habits, relaxation techniques, and stress management. Furthermore, patients are also consulted on changing habits, adjusting behavior, and exercising. Patients are instructed to adjust their behavior: quit harmful habits to limit pain in daily functional activities, maintain scientific sleep, maintain good head, neck, and shoulder activities, soft diet and avoid hard foods, do exercises twice a day: open mouth wide combined with cool compresses and warm compresses.

RADIATION

Low level laser therapy combined with Self-Management Program

LLLT may facilitate the release of endogenous opioids, tissue repairment and cellular respiration, increase vasodilatation and pain threshold, and decrease inflammation. Diode low-energy laser machine (Sirolaser blue, Dentsply) are set the default mode according to the correct parameters before use: wavelength 660nm, energy level 2.5 J/cm2, power source 100mW. The projection head is placed perpendicular to the muscle being projected. The laser light is shined on the pain point at the beginning of the treatment, then it will shine on muscle points in turn: temporal muscle (anterior, middle, posterior), masseter muscle (upper, middle, lower), 5 points around the temporomandibular joint area (superior, anterior, lateral, posterior, posterior subcondylar). Each masticatory muscle area is treated for 20 seconds, 3 sessions /week (different days), 10 sessions total. In addition, patients are still instructed Self-Management Program as group 1.

DEVICE

Occlusal Splint combined with Self-Management Program

Maxillary occlusal splints are made of hard acrylic after taking impressions of the upper dental arches, recording of centric relation (Okeson). Splints are adjusted to provide even occlusal contact during jaw closing and chewing, and canine and incisor contact during protrusive movements of the jaw. Patients are instructed to use the splint each night at least 8 hours/day for a period of 8 weeks.In addition, patients are still instructed Self-Management Program as group 1.
