Aims and Objectives: The purpose of this prospective clinical study was to evaluate and compare the clinical effectiveness of gallium-aluminum-arsenide (GaAlAs) diode laser alone and with topical 2% Stannous fluoride gel in the management of dentinal hypersensitivity. Materials and Methods: Thirty patients (14 males and 16 females, age 19-70 years), contributing 534 teeth with dentin hypersensitivity (DH) were assessed by air stimuli and measured by verbal rating scale (VRS). For each patient, the sensitive sites were randomly divided into Group 1(G1) (267 teeth), treated by application of 2% stannous fluoride gel followed by application of GaAlAs diode laser (Sunny Germany, 980 nm, 2W, 25 Hz) in continuous mode and Group 2 (G2) (267 teeth), was subjected to only diode laser at the same parameters employed in G1. VRS recordings were assessed before treatment, 15 min after the laser application and at the end of 2, 7, 14 and 30 days after treatment. Results: Both the Groups have shown significant reduction in DH after the laser irradiation but reduction in DH was more evident in G1 than G2. Conclusion: Diode laser is a useful device for DH management and addition of stannous fluoride has synergistic effect on laser desensitization effect.
