| Abstract This study aims to compare the effectiveness of three different pliers in debonding stainless steel and ceramic brackets, also to evaluate enamel surface damage and the site of bond failure after debonding. Sixty premolars, extracted for orthodontic purposes, were divided into 3 groups of 20. The enamel surfaces were examined with 10X magnifying lens. Two types of bracket (stainless steel and ceramic) was bonded and debonded in each group using: conventional debonding pliers, bracket removal pliers, and ligature wire cutter. After debonding, the enamel surfaces were inspected under a stereomicroscope to determine the predominant site of bond failure. Then stereomicroscope was used to evaluate enamel surface damage after the removal of residual adhesive. The enamel surface damage showed a statistically significant difference in ceramic bracket groups, whereas, it was statistically insignificant in stainless steel bracket groups. The amount of the adhesive remained on the tooth surface was statistically insignificant in both stainless steel and ceramic bracket groups. The predominant failure site was within the adhesive itself for both types of brackets. The enamel surface damage that results from debonding of ceramic brackets was higher than that found with the stainless steel brackets especially with the use of bracket removal pliers "used in this study" | ||
