Dentinal hypersensitivity is a common clinical condition characterized by short, sharp pain arising from exposed dentin in response to thermal, tactile, or evaporative stimuli. It can significantly affect oral health-related quality of life and routine dental care. Various treatment approaches have been proposed, including laser therapy and bioactive materials, with differing mechanisms of action and clinical outcomes. This randomized controlled clinical trial aims to compare the effectiveness of an 810-nm diode laser, a bioactive glass-based desensitizing agent, and a placebo in reducing dentinal hypersensitivity. Eligible participants with clinically diagnosed dentinal hypersensitivity will be randomly assigned to one of three parallel treatment groups. Pain intensity will be assessed using a visual analog scale following standardized air stimulus testing at baseline and at predefined follow-up intervals. The study will evaluate both immediate and long-term changes in hypersensitivity over a 12-month follow-up period. The findings are intended to provide clinical evidence on the comparative performance of diode laser therapy and bioactive glass in the management of dentinal hypersensitivity.
