Abstract
INTRODUCTION: Interproximal reduction (IPR) is an orthodontic technique used to address space constraints by removing small amounts of enamel between teeth. This research aims to evaluate the impact of IPR on enamel surface integrity, tooth sensitivity, and the long-term stability of orthodontic results. METHODS: The study was conducted on a sample of 50 patients undergoing orthodontic treatment. Three parameters were evaluated: changes in enamel thickness pre- and post-IPR, post-treatment sensitivity using a visual analog scale, and relapse tendencies measured over a 12-month follow-up. Data were statistically analyzed using paired t-tests. RESULTS: Enamel thickness was reduced by an average of 0.25 mm post-IPR (P < 0.05). Mild post-treatment sensitivity was reported by 30% of the patients. Relapse was minimal, with no statistically significant correlation with the extent of IPR performed. CONCLUSION: IPR is a safe and effective method in orthodontic treatment with minimal enamel reduction, mild short-term sensitivity, and no significant long-term relapse. These findings support the continued use of IPR as a conservative approach to space management.
