Aim: The aim of this study was to compare the effect of potassium nitrate topical desensitizing agent with low-level laser therapy for dentinal hypersensitivity. Materials and Methods: Sixty patients were recruited for the study. Patients were divided into three groups: group 1, low-level laser irradiation for dentinal hypersensitivity; group 2, 5% potassium nitrate toothpaste topically; and group 3, low-level laser irradiation plus 5% potassium nitrate. Results: Pain was significantly reduced postoperatively in all three groups. Best pain reduction was for the laser and potassium nitrate group. No significant difference was observed with combination of low-power laser and potassium nitrate. Conclusion: Potassium nitrate and low-level laser irradiation proved equally effective for reducing dentinal hypersensitivity in patients. No significant advantage was observed with laser and potassium nitrate combination.
