About this study
Official title: Comparison of Bond Failure Rate of Orthodontic Brackets Bonded With V-Prep and Resin-Modified Glass Ionomer Cement Versus Conventional Acid-Etch Composite Resin: A Split-Mouth Randomized Controlled Trial
Ethical approval will be obtained by the FUSH and informed consent will be obtained from individual patients/guardians in writing. Inclusion and exclusion criteria will be used to obtain random patient samples within the Orthodontic Department of FUCD\&H and Baseline parameters like age, gender, O'Leary Plaque Score, malocclusion classification type and degree of overbite will be recorded. Patients will be screened one at a time if they are eligible. For this purpose, sequentially numbered, opaque sealed envelopes will be opened just before the bonding assignment for allocation concealment. Both orally and in writing to all patients. Tooth surfaces will be pumiced and standardized.
While, the Primer light-cured for 10-sec each item, the Control group (enamel) etched for 30-sec, washed for 15-sec and air dried to a frosty white. The tough brackets will be attached, with a baseline underneath, with a thin layer of composite resin pressed down on optimum. Light cured for 10 seconds on mesial and distal surfaces to remove excess adhesive (STEP 7).

Group II (V-Prep): Enamel surface was were in contact with 0%-1.5% diluted Sodium Hypochlorite during 60 seconds, rinsed and thoroughly dried; then the V-Prep was applied. 37% phosphoric acid gel for 30 Sec, rinsed for 15 Sec and dried until a frost white appearance on the etched enamel area. The first is called Primer and will be light cured for 10 seconds. A template will then be provisionally fixed to secure the bottom of the bracket in place with Resin-Modified Glass Ionomer Cement. Clean of excess adhesive, and cure for 10 seconds mesial and distal.
Then instead of going to bonding, this will be taken out and ligated to a 0.012-in Ni-Ti archwire. Will follow a 30 days interval series of 6 follow-up visits, monthly visits throughout 6 months

Questions about this trial
What is this clinical trial studying?
A study testing V-Prep and Resin-Modified Glass Ionomer Cement and Conventional Acid-Etch Composite Resin in people with Bracket Failure and Bracket Bonding, run by Foundation University Islamabad at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 18 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Bond Failure Rate of Orthodontic Brackets (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
