The goal of this randomized clinical trial is to evaluate whether combining a potassium nitrate gel with diode laser therapy is more effective in treating dentinal hypersensitivity compared to using the gel alone. The study involves adult participants with at least two teeth affected by dentinal hypersensitivity. The main questions it aims to answer are: Does the combined use of potassium nitrate gel and diode laser therapy reduce dentinal hypersensitivity more effectively than gel alone? How does this combined treatment impact sensitivity-related quality of life over time? Researchers will compare the outcomes between the two groups (combined therapy versus gel alone) to determine the effectiveness of the combined treatment. Participants will: Undergo assessments of dentinal hypersensitivity using the Shiff Air Index (SAI) and Visual Analog Scale (VAS) at baseline and at follow-ups (1 month, 3 months, and 6 months post-treatment). Complete a questionnaire to evaluate the impact of dentinal hypersensitivity on daily life at baseline and after 6 months.
