ckground: Dentine hypersensitivity (DH) is characterized by pain after stimuli that usually provoke no symptoms. This study compares the effect of desensitizing agent, iontophoresis & diode laser in the treatment of dentinal hypersensitivity for 3 months. Materials & method: Total 255 teeth with DH were assessed by air, thermal and tactile stimuli measured with Verbal Rating Scale (VRS). Teeth were randomly assigned and equally divided (85 teeth each group) into 3 groups, Group I treated by CO2 Laser, Group II treated by 2% NaF with iontophoresis and Group III treated by 2% NaF varnish. Sensitivity was assessed at baseline, 30 minutes, 24 hours, 1 week, 1 muonth and 3 months interval. Statistical analysis was done using one-way ANOVA test. Result: There was statistically significant reduction in DH with all 3 groups, but better results were yielded with 2% NaF with iontophoresis. (p value<0.05) Conclusion: CO2 laser shows efficient reduction in Dentin Hypersensitivity in compare with iontophoresis and varnish.
