This study evaluated the

preliminary results of a rapid protocol for laser

treatment of patients with myofascial pain and

mouth opening limitation. The sample was

composed of nine patients who were treated

with low-level laser therapy using the infrared tip.

Two sessions of laser therapy were performed

with a 48 hours interval between them. Mouth

opening was significantly better immediately

after the first session, and when comparing the

initial mean to the second session. Regarding

spontaneous pain, 44.44% of the patients

related complete remission. The rapid treatment

protocol was shown to be effective in increasing

the mouth opening width in patients with

myofascial pain and mouth opening limitation.
