Context: Ultrasonic scaling is a routinely performed procedure in dental practice. During ultrasonic scaling, sensitivity of teeth is a common occurrence. The sensitivity of teeth causes discomfort and pain to many patients. The potassium nitrate is an antihypersensitivity agent used effectively in dentifrices. Aims: The aim of the study is to evaluate the efficacy of 5% potassium nitrate gel application on the reduction of sensitivity during ultrasonic scaling. Settings and Design: This study is a randomized controlled trial with a split-mouth design. A total of 100 patients were recruited in the study after informed consent. Subjects and Methods: Mandibular anterior teeth were selected as the area for study. About 5% potassium nitrate gel was applied to the left or right side of the teeth. After 5 min, ultrasonic scaling was performed for both test and control sides. Visual analog scale (VAS) and patient satisfaction were recorded for both the groups. Statistical Analysis Used: An unpaired t-test was used to analyze the mean VAS scores with the area treated with or without application of 5% potassium gel during ultrasonic scaling. Chi-square test was used to analyze the satisfaction level with the test and control group. Results: The mean VAS scores and patient satisfaction for the test group were (P < 0.001) statistically significant as compared to the control group. Conclusions: Potassium nitrate gel can be effectively used before ultrasonic scaling to reduce sensitivity.
