Aim: The present randomized study was aimed to compare the efficacy 5% potassium nitrate (KNO 3 ) toothpaste, low-level laser therapy (LLLT), and LLLT with 5% KNO 3 toothpaste in the treatment of dentinal hypersensitivity (DH). Materials and Methods: Total of 45 patients complaining of DH with visual analog scale (VAS) score being ≥2 were recruited and were divided into three groups. Group A was treated with 5% KNO 3 toothpaste, Group B using LLLT along with the application of 5% KNO 3 toothpaste, and Group C using LLLT alone. VAS scores were recorded at the baseline, 1 st , 2 nd , and 3 rd weeks by the examiner who is blinded toward the treatment. The sensitivity response was evaluated using air spray and tactile sensation (explorer). Results: A greater reduction of DH was recorded at the end of 3 weeks in Group C and Group B when compared to Group A. Better results were noted in Group C at the end of the 1 st week when compared to Group B. According to this study, there was no additional benefit of using toothpaste along with LLLT. Conclusion: A greater reduction of DH was recorded at the end of 3 weeks in Group C and Group B when compared to Group A. Better results were noted in Group C at the end of the 1 st week when compared to Group B. According to this study, there was no additional benefit of using toothpaste along with LLLT.
