Summary
This randomized split-mouth clinical trial evaluates enamel surface preservation, pulpal temperature variation, and patient-reported discomfort during ceramic orthodontic bracket removal using two Erbium-doped yttrium aluminum garnet (Er:YAG) laser parameter settings compared to conventional mechanical debonding. Pulpal temperature is monitored in real time using a thermocouple device. Enamel integrity is assessed using the Adhesive Remnant Index (ARI) under 40× magnification. The study aims to determine optimal laser parameters ensuring safe and conservative bracket removal.
