The objectives of this cross-sectional study are 1) to compare the Adhesive Remnant Index (ARI) score between metal and ceramic brackets and 2) to compare the mean percentage of the adhesive remnant on the bracket base. The data were obtained from patients who required debonding of fixed orthodontic appliances. The patients were allocated into three groups; 1) conventional metal brackets, 2) self-ligating metal brackets, and 3) self-ligating ceramic brackets. All brackets were mechanically debonded using recommended pliers. After debonding, dental disclosing solution was applied on the adhesive remnant, and ARI score was recorded based on the image analysis measurement of the photograph. All debonded brackets were evaluated under a stereomicroscope, and the percentage of the adhesive remnant on the bracket base was calculated using image analysis. The data was analysed using SPSS version 24.0 and the level of statistical significance set at p ＜ 0.05. A total of 192 brackets which comprised of 64 brackets in each group were evaluated for this study. There was statistically significant difference (p＜0.05) between three types of brackets in the ARI assessment on the tooth surface. The result was consistent with the image analysis of the mean percentage of adhesive remnant on the bracket base. The result showed a statistically significant difference between self-ligating metal brackets and other types of brackets. The self-ligating metal brackets had most adhesive remain on the tooth surface and had the smallest mean of percentage adhesive remnant on the bracket base.
