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 GaAIAs 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 days respectively and were examined again after 6 days.
And the obtained results were as follows
1. The IMO 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 of irradiated group increased more significantly after treatment than non-irradiated group.
