Comparative Evaluation Between Different Manual And Ultrasonic Orthodontic Bracket Debonding Methods In Terms Of Adhesive Remnants, Pain Perception And Incidence Of Bracket Distortion– An In-Vivo Study

Abstract

Aim: To evaluate and Compare different Manual and Ultrasonic Orthodontic bracket debonding Methods in terms of Adhesive Remnants, Pain Perception and Incidence of bracket Distortion

Material and Method: A sample size of 50 patients (>18 years) having fixed orthodontic treatment for both upper and lower arches having MBT prescription 0.022-inch metal brackets and ready for orthodontic bracket debonding were selected according to inclusion and exclusion criteria. In each patient four Quadrants of oral cavity were randomly distributed amongst four methods Method -I: Wing Method Debonding, Method -II: Base method Debonding, Method -III: Scaler-tip angulation at 45º and Method –IV: Scaler-tip angulation at 0º by using lottery method.

Results: In AIR Index, Median Value of Wing Method is 2.4, which is highest followed by the median value of Scaler-tip angulation at 45º is 1.4 and Scaler-tip angulation at 0º is 1.4 which is Same followed by the Base method whose median value is 0.4 which is lowest. In Bracket Failure Score, Median Value of Base Method is 4.5, which is highest followed by the median value of Wing Method which is 4. Median value of Scaler-tip angulation at 0º and Scaler-tip angulation at 45º is same which is 1. In Visual Analogue Scale, Median Value of Wing Method and Base Method is 5 which is same and Median value of Scaler-tip angulation at 0º and Scaler-tip angulation at 45º is same which is 2.

Conclusion: Base Method showed lowest AIR score indicating less Adhesive remnants on enamel surface after Orthodontics Bracket debonding. Scaler-tip angulation at 0º and Scaler-tip angulation at 45º showed less incidence of bracket distortion compared to wing method and base method. Scaler-tip angulation at 0º and Scaler-tip angulation at 45º showed reduced pain level compared to Wing Method and Base Method
