Effectiveness of Diode Laser (810nm and 980 nm) in Treatment of Dentine Hypersensitivity

Abstract

The successful treatment of dentine hypersensitivity was challenge due to difficult control of the causative factors. Treatment through conventional methods (using desensitizing agent} were not effective in all patients. Laser therapy was introduced as new treatment modality for dentine hypersensitivity. This study aimed to evaluate the effectiveness of diode laser on treatment of dentine hypersensitivity. A total of 35 teeth of 3voluntary male and female individuals (age from 30 - 60 years) The patients were all in a good health , and not under any medications for the last 72 hours preceding the treatment , and were not subjected to any periodontal surgery in the past 3 months. The severity of pain was recorded in analogous visual scale. Two different wavelengths (810nm and 980nm) diode laser was applied to a quadrant in a power 1 watt and 60 seconds exposure time. Comparison between different variables by T test with the level of significance set at p=0.005. The results showed that there was significant decrease of sensitivity, a significance (p<0.05) on both wavelengths especially when 810 nm was used immediately after exposure. The diode laser (810 nm and 980 nm) therapy was effective on treating dentine hypersensitivity. Decreasing wavelength led to decrease sensitivity.
