Abstract

To investigate the effect of low level laser therapy, the author selected 37 dental students with tender points in both masseters and trapeziuses, also measured maximum comportable opening(MCO), Numerical analog scale(NAS) and pressure pain threshold (PPT). 20 subjects were assigned randomly and were treated with GaAlAs diode laser after ultrasound. The other 17 subjects were treated with ultrasound and laser without irradiation. All the subjects were treated after 2 and 4 day respectively and were examined again after 6 days. And the obtained results were as follows : 1. The MCO of irradiated group increased more significantly after treatment than non-irradiated group. 2. The NAS of irradiated group decreased more significantly after treatment than non-irradiated group. 3. The PPT or irradiated group increased more significantly after treatment than non-irradiated group.
