In dentistry today, LLLT is used on patients with temporomandibular disorders (TMDs), mainly for radiating pain in the masticatory muscles. This study evaluated how the number of laser applications can affect the masseter muscle.
Thirty animals were randomly distributed into groups according to the number of laser applications they would receive. It was found that six applications of laser had a positive effect on the muscle physiology, but there was little difference between 6 and 10 applications.
The SDH enzyme activity revealed that the number of laser applications increases the metabolic pattern of the muscle fibers. The authors suggest that further studies should be done to confirm if six applications are enough to produce the same clinical effects as more treatments.
This is an important study because it supplies data on the cost/benefit ratio of laser therapy. Insurance companies need to be informed of this type of information so they can improve reimbursement for laser therapy!
