EVALUATION OF DIFFERENT TECHNIQUES FOR DEBONDING OF CERAMIC BRACKETS (AN IN VITRO STUDY)
Objective: To compare different techniques for debonding of ceramic brackets in terms of adhesive remnant index (ARI). Material and methods: A sample of 100 extracted human premolars were randomly and equally allocated into 5 groups of 20. Thereafter, monocrystalline ceramic brackets were bonded to teeth using light cure composite resin. Among the 5 groups; group I: served as control, group II: chemical assisted debonding using peppermint oil, group III: ultrasonic assisted debonding, group IV: diode laser assisted debonding, and group V: Er: YAG laser assisted debonding. Brackets were then debonded using a universal testing machine, followed by ARI assessment. Results: A statistically significant higher ARI scores was found solely in Er:YAG laser assisted debonding. Yet, no significant difference was found with chemical, ultrasonic, and diode laser assisted debonding. Conclusion: Er:YAG laser could be effective for debonding of ceramic brackets. Hence, this method might be recommended to alleviate enamel damage.
