Background: Dentine hypersensitivity (DH) is an abnormal response of the exposed vital dentine to various stimuli. The present study was conducted to compare diode laser and fluoride varnish in dentin hypersensitivity. Materials & Methods: This study was conducted on 50 patients of dentine hypersensitivity which were divided into 2 groups (25 each). Group I patients were treated with diode laser (DL) and group II patients were treated with fluoride varnish. All patients underwent scaling and dentine hypersensitivity (DH) was evaluated by tactile and evaporative stimulus. VAS score was recorded at baseline, 15 days, 1 month and 2 month. Results: The mean VAS score for tactile stimulus at baseline in group I was 7.12, at 15 days was 6.15, at 1 month was 5.17 and at 2 months was 4.24. In group II, at baseline score was 7.18, at 15 days was 6.20, at 1 month was 5.93 and at 2 months was 5.28. The mean VAS score for air blast stimulus at baseline in group I was 8.12, at 15 days was 6.78, at 1 month was 5.40 and at 2 months was 3.92. In group II, at baseline score was 7.50, at 15 days was 6.75, at 1 month was 6.42 and at 2 months was 6.72. The difference was significant (P< 0.05). Conclusion: Authors found that there was reduction in tactile and air blast stimulus recorded on VAS in both groups. After 2 months diode laser revealed better results. Hence both diode laser and fluoride varnish can be effectively used in dentine hypersensitivity.
