Abstract

The aim of the present study was to determine the effectiveness of GaAlAs laser therapy with lambda670nm laser on the treatment of dentin hypersensitivity. Thirty-two intact human teeth were evaluated, the sensitivity of which to thermal (cold water), mechanical (probe) and evaporative (air) stimuli was recorded before and immediately after irradiation. Whenever desensitization was not observed after the first application, the patient was scheduled for a maximum of three further applications at 4-day intervals. The results demonstrated that laser therapy yielded a statistically significant reduction (p<0.05) in dentine hypersensitivity to the three stimuli analyzed. According to the results, the utilization of GaAlAs laser therapy (lambda670nm) required just one application for the thermal and mechanical stimuli, whereas the evaporative stimulation demanded at least two applications of laser for the achievement of a similar effect.
