OBJECTIVES: This single-blinded randomized control trial aimed to assess the effect of Low-Intensity Pulsed Ultrasound (LIPUS) on the duration of alignment and leveling stage, and to assess patients' pain and discomfort following the procedure.
MATERIAL AND METHODS: 30 participants (18-35 years) were recruited, of whom 22 were selected with Little's Irregularity Index of 1-6mm following a non-extraction protocol, and were randomly allocated into two groups using a lottery method. The test group underwent the LIPUS application for 20 minutes on days 0, 3, 5, 7, 15, and every 15 days until completion of alignment and leveling. The control group was subjected to a placebo protocol. Stage models were fabricated every 21st day and the duration taken for completion of alignment was recorded. The patient's satisfaction scale was documented using a questionnaire on a Visual Analog Scale.
RESULTS: A statistically significant reduction was found in treatment time for alignment and leveling. A 22% reduction in total duration for alignment and leveling was observed (p=0.027). No appreciable difference in pain and discomfort was observed between the groups.
CONCLUSION: The application of LIPUS for 20 minutes on days 0, 3, 5, 7, 15, and every 15 days until alignment completion showed a significant reduction in the duration taken for alignment and leveling of teeth.
