Introduction: Dentin hypersensitivity is a very common clinical condition of the teeth, associated with the exposure of the dentin to external environment of the mouth. There is still no promising solution for dentin hypersensitivity due to little knowledge about its etiology and predisposing factors. The purpose of this study was to compare the efficacy of gallium-aluminum-arsenide diode laser (GaAlAs) and dentin bonding agent in the treatment of dentin hypersensitivity.
Materials and Method: Sixty permanent teeth with diagnosis of dentin hypersensitivity were selected from patients reporting the department. The selected teeth were divided into two groups: In group I, teeth were treated with 980 nm GaAlAs laser for 1 min at 30mW and in group II, teeth were treated with dentin bonding agent. Sensitivity was assessed by evaporative stimulus, measured with the criteria proposed by Uchida at baseline and after treatment; immediately, at 15 and at 30 days.
Results: The mean dentin hypersensitivity in both the laser and dentin bonding agent group was 1.9 ± 0.76.After 30 days, the degree of dentin hypersensitivity in Laser treated group (0.90 ± 0.80) was significantly lower than that of Dentin Bonding Agent group (1.40 ± 1.07)(p< 0.05), thereby showing greater clinical efficacy of diode Laser over Dentin Bonding Agent for the treatment of dentin hypersensitivity.
Conclusion: The dentin bonding agent had less desensitizing efficacy compared with GaAlAs laser. However, the desensitizing effect of the dentin bonding agent still could be considered an effective therapy for treating dentin hypersensitivity.

Dentin hypersensitivity (DH); GaAlAs diode laser; Dentin bonding agent.
Key Message: Dentinal hypersensitivity is a global oral health issue and a significant challenge for most dental professionals. With the advent of laser technology and its growing utilization in dentistry, an additional effective therapeutic option with lesser side effects is available for the treatment of dentinal pain
