Abstract

Abstract: PURPOSE: To compare enamel surface state and operating time following debonding by using 5 different resin removal methods. METHODS: Forty healthy human premolars extracted for orthodontic purpose were selected and then divided into 5 groups randomly based on different resin-removal methods, 8 in each group. After regular bonding brackets and debonding, tungsten carbide bur (group A), tungsten carbide bur+silicon particles(group B), corundum bur(group C), corundum bur+silicon particles (group D) and silicon particles (group E) were used respectively to deal with the enamel surfaces. The operating time(T) of each group was recorded. The samples were observed under scanning electron microscope (SEM), and enamel damage index(EDI) was recorded. The scores of EDI were analysed using SPSS 20.0 software package . RESULTS: The order of EDI was group C>group D>group A >group B>group E, significant difference was found between 5 groups (P<0.05). The order of operating time was group E>group D>group B>group A>group C, significant difference was found between 5 groups (P<0.05). CONCLUSIONS: Using tungsten carbide bur followed by silicon particles to remove residual resin on enamel surface causes less damage to the enamel surface, and requires reasonable time.
