Abstract: Background: Dentin hypersensitivity is a prevalent oral problem affecting the oral health quality of life of the adult population. Patients with periodontal diseases and faulty tooth brushing technique are particularly at a higher risk of root surface exposure due to recession and cervical abrasion which may lead to dentin hypersensitivity. Aim: The aim of the study was to evaluate the efficacy of fluoride varnish (sodium fluoride [NaF]), diode laser, and the combination of both in the treatment of dentin hypersensitivity. Materials and Methods: Thirty patients aged 20?60 years suffering from dentin hypersensitivity to air - blast, cold, and tactile stimulation corresponding to score 4 and above on the Visual Analog Scale (VAS) in three quadrants with hypersensitive teeth. were selected. Hypersensitive teeth were allotted to Group 1 ? 5% NaF varnish application alone, Group 2 ? 980 - nm gallium? aluminum?arsenide laser (GaAlAs) diode laser (0.5 W) irradiation alone, and Group 3 ? NaF varnish application, followed by diode laser irradiation. VAS score was recorded at baseline, immediate post op, 1 week, 1 month, 3 months. Results: A statistically significant reduction in dentin hypersensitivity was observed in all the three groups, from the baseline to 3 months follow - ups (P < 0.05). Group 2 and Group 3 demonstrated a significantly higher reduction (P < 0.05) in dentin hypersensitivity for all the stimuli as compared to Group 1 at all follow - up intervals. However, statistically significant difference (P< 0.05) was also present between Group 2 and Group 3 at all follow - ups. Conclusion: Sodium fluoride varnish followed by Diode laser application is significantly more effective than fluoride varnish alone and/or diode laser alone in the treatment of dentin hypersensitivity.
