Abstract :Objectives: Repeated bracket failure is a common problem during orthodontic treatment of Class II division 2 malocclusions leading to unaesthetic results due to enamel color-change. This study aims to examine the effect of repeated debonding of two different metal-brackets followed by two different polishing procedures on enamel color. Material and Methods: Randomly selected 40 intact-non-carious-premolars were separated into two main groups of 20 as Group 1 insert ignore into journalissuearticles values(G1); and Group 2 insert ignore into journalissuearticles values(G2);. 80-gauge foil-mesh-base and micro-etched-base metal-brackets were bonded to teeth in G1 and G2, respectively. Both groups were subdivided into two subgroups as A or B, according to polishing techniques with whitestone-bur and sof-lex-disks respectively. Color evaluations were performed using Vita EasyShade before bonding brackets insert ignore into journalissuearticles values(T0); and after each debonding insert ignore into journalissuearticles values(T1, T2, T3);. Adhesive Remnant Index insert ignore into journalissuearticles values(ARI); scores were evaluated visually. ANOVA with post-hoc analysis with a Bonferroni adjustment was utilized to compare color difference insert ignore into journalissuearticles values(ΔE); between time points in each group. Results: Most significant difference in ΔE insert ignore into journalissuearticles values(11.7 ± 3); was in G1A at T1. In T2 the most significant difference in ΔE was noticed in G1B and G2A. There was no significant difference in ARI scores according to the brackets or the polishing methods. Repeated debonding of micro-etched-base-brackets followed by adhesive removal with a tungsten-carbide-bur and polishing with sof-lex-disks did not cause any significant change in ΔE. Conclusion: Repeated bracket bonding after bracket loss may cause damage and subsequent discoloration of the enamel surface causing a negative effect on esthetics if correct cleaning protocols are not followed.
