Infrared thermal analysis of the masseter region after irradiation with led low level laser – clinical study

Abstract

Introduction: According to some studies, therapy with low-intensity laser can promote changes in peripheral microcirculation. Objective: The aim is, through this study to analyze the facial temperature after being subjected to irradiation with laser and LED. Methods: Nine volunteers, mean age 28 years, received radiation laser (660 nm, 30 mW, 7.5 J/cm2, 10 seconds) or LED (640 ± 20 nm, 30 mW, 4 J/cm2, 20 seconds). Results: The contralateral (control) of therapy showed no significant differences in post-irradiation. Conclusion: The results suggest that, at the dose tested, there were no systemic effects on the surface temperature postirradiation. Therapies with the parameters used (test) for the laser did not cause significant difference in local surface temperature, however, the LED may have a modulatory effect of peripheral temperature within 5 minutes after irradiation, which could aid in the postoperative period, but requires further studies.
