Comparison of the efficiency of two alternative therapies for the management of temporomandibular disorders.

Objective

To investigate the effect of ozone and low-level laser (LLL) therapies on pain and function in patients with disc displacement with reduction.

Methods

Eighty temporomandibular joints were divided into four groups, namely ozone and laser treatment groups, and two placebo groups. Ozone and LLL therapies were applied over six sessions.

Results

Pain on palpation scores demonstrated a statistically significant decrease over time in the treatment groups. Sham laser therapy only reduced the pain on palpation in temporomandibular joints; whereas, sham ozone only affected masseter muscle pain. The ozone treatment group demonstrated significantly better pressure pain threshold scores and mandibular movements than the other groups; however, pressure pain threshold scores of the masseter inferior were significantly higher in the laser group.Discussion: This study supports the use of ozone for pain reduction as an alternative treatment modality and LLL as a supportive therapy for temporomandibular disorders.
