Official title
Comparison of Orthodontic Bracket Bond Failure Using Acid Etching With or Without Sandblasting Method for the Preparation of Enamel
Overview
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 .
Interventions
- Procedure Sandblasting with acid etching vs Acid etching alone
Sandblasting will be applied onto the vestibular surfaces of the teeth before applying the etchant; - Procedure Acid Etching only
Acid etching will be applied onto the vestibular surfaces of the teeth for enamel preparation.
Primary outcome measures
- To compare the bracket bond failure rate using acid etching with or without sandblasting method for the preparation of enamel. [Time frame: 6 months]
Eligibility criteria
Inclusion criteria
- Participants with good general health condition and oral hygiene status.
- Age range of the patients will be 18 years and above.
- Sex of the participants will be both male and female.
- Patients with full permanent dentition present (excluding 3rd molar).
- Patients with enamel integrity, absence of traumatic or carious lesion.
- Participants who had no enamel pretreatment procedure performed with chemical agents.
- Participants with no crossbite, scissor bite or occlusal interference (to prevent any potential early bond failure).
Exclusion criteria

- Patients with craniofacial syndromes.
- Patients who present with partially erupted teeth with hypoplasia.
- Patients for whom a rapid expander or a fixed functional appliance will be planned.
