Comparison of Orthodontic Bracket Bond Failure Using Acid Etching With or Without Sandblasting (AE SBE BF BB)

May 24, 2026 updated by: Tanzila Rafique

Comparison of Orthodontic Bracket Bond Failure Using Acid Etching With or Without Sandblasting Method for the Preparation of Enamel

The goal of this clinical trial is to assess if sandblasting before acid etching reduce orthodontic bracket bond failure in fixed orthodontic treatment. The main question it aims to answer is:

• What are the differences in bracket bond failure rate between acid etching with or without sandblasting method for the preparation of enamel? Researchers will compare acid etching with sandblasting method to acid etching without sandblasting method for enamel preparation to see if sandblasting prior to acid etching reduce bracket bond failure rate.

Participants will:

  • Receive sandblasting of enamel before acid etching on one side of the mouth and only acid etching on the contralateral side for enamel preparation.
  • Participants would visit at the the OPD of Hospital at 3 weeks interval for follow up and for a total duration of 4 months to assess the changes. The number of bracket bond dislodgements at each session will be recorded .

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Sandblasting
Sandblasting will be applied onto the vestibular surfaces of the teeth before applying the etchant
Procedure: Sandblasting with acid etching vs Acid etching alone
Sandblasting will be applied onto the vestibular surfaces of the teeth before applying the etchant;
Active Comparator: Acid Etching Alone
Only acid etching will be applied onto the vestibular surfaces of the teeth for enamel preparation.
Procedure: Acid Etching only
Acid etching will be applied onto the vestibular surfaces of the teeth for enamel preparation.
