Comparison of Orthodontic Bracket Bond Failure Using Acid Etching With or Without Sandblasting

The goal of this clinical trial is to assess if sandblasting before acid etching reduceorthodontic bracket bond failure in fixed orthodontic treatment. The main question itaims to answer is:• What are the differences in bracket bond failure rate between acid etching with orwithout sandblasting method for the preparation of enamel? Researchers will compare acidetching with sandblasting method to acid etching without sandblasting method for enamelpreparation to see if sandblasting prior to acid etching reduce bracket bond failurerate.Participants will: ‐ Receive sandblasting of enamel before acid etching on one side of the mouth and onlyacid etching on the contralateral side for enamel preparation. ‐ Participants would visit at the the OPD of Hospital at 3 weeks interval for followup and for a total duration of 4 months to assess the changes. The number of bracketbond dislodgements at each session will be recorded .
