| Abstract | ||
| Objective: This study aims to evaluate the efficiency of the Er,Cr:YSGG laser compared to tungsten carbide bur in removing adhesive remnants from the enamel surface after orthodontic treatment. Materials and Methods: Stainless steel orthodontic brackets were bonded to freshly extracted 30 human premolars. Teeth were divided into three groups; group I used the tungsten carbide bur 6 fluted with a high-speed contra, group II used the Er,Cr:YSGG 2780 nm using 2 W, 15 Hz, H mode (60 µs), 133 m J, and group III used the Er,Cr:YSGG 2780 nm using 2.5 W, 30 Hz, S mode (700 µs), 166 m J. After the debonding process, enamel damage was tested by the enamel damage index (EDI) under a stereomicroscope. Results: There was a statistically significant difference between median EDI scores in the three groups (P-value <0.001, effect size = 0.66). Pair-wise comparisons between groups revealed that there was no statistically significant difference between Groups I and III; both showed statistically significantly higher median EDI scores than Group II. Samples of groups I, and III show a score of 2, while group II showed a score of 1. Conclusion: The Er,Cr:YSGG laser with parameters: 2 W, 15 Hz, H mode (60 µs), 133 mJ showed better enamel surface appearance. and the Er,Cr:YSGG laser can be used as an alternative to the tungsten carbide bur in adhesive remnant removal after orthodontic bracket debonding | ||
