The objective of this randomized clinical trial is to evaluate and compare the effect of four different residual adhesive removal techniques following orthodontic bracket debonding on postoperative tooth hypersensitivity. The study compares low-speed tungsten carbide burs against fiberglass burs, white stone burs, and rubber-impregnated polishing points. Postoperative hypersensitivity will be evaluated using a Visual Analogue Scale (VAS) with an air-blast stimulus test immediately after debonding, at 24 hours, and at 7 days follow-up.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Residual composite adhesive remnants on eligible teeth are cleaned using a 12-fluted low-speed tungsten carbide bur operated at 15,000-20,000 rpm under continuous water cooling.
Device: Low-Speed Tungsten Carbide Bur
Residual composite adhesive remnants on eligible teeth are cleaned using a fiberglass bur operated at 15,000-20,000 rpm under continuous water cooling
Device: Fiberglass Bur
Residual composite adhesive remnants on eligible teeth are cleaned using a fine-grit white stone bur (aluminum oxide) operated at 10,000-15,000 rpm under continuous water cooling.
Device: White Stone Bur
Residual composite adhesive remnants on eligible teeth are cleaned using a rubber-impregnated polishing point operated at 10,000-15,000 rpm under continuous water cooling
Device: Rubber-Impregnated Polishing Point
Composite resin is removed using a 12-fluted tapered low-speed tungsten carbide bur operated at 15,000-20,000 rpm under continuous air-water spray irrigation until all visible adhesive remnant is completely eliminated.
Composite resin remnants are eliminated using a fiberglass resin-removal bur operated at 15,000-20,000 rpm under continuous air-water spray irrigation until all visible material is completely removed.
Composite resin remnants are removed using a fine-grit Arkansas white stone bur (aluminum oxide) operated at 10,000-15,000 rpm under continuous air-water spray irrigation until the enamel surface is clear.
Residual adhesive tags are removed and polished using a rubber-impregnated composite polishing point operated at 10,000-15,000 rpm under continuous air-water spray irrigation
Postoperative Hypersensitivity
Patient-reported pain and hypersensitivity evaluated using a Visual Analogue Scale (VAS) score ranging from 0 (No pain) to 10 (Unbearable severe pain) in response to a 2-second dental syringe air-blast stimulus test.
Time frame: Baseline (immediately post-debonding, before clean-up), 24 hours, and 7 days post-adhesive removal.
Procedure Time
Time taken to perform complete residual adhesive removal per tooth, measured using a stopwatch
Time frame: Immediately during the clean-up procedure.

Start is estimated for Nov 2026; primary completion for Jun 2027, 7 months later.
Of 111 non-industry interventional studies with no phase under Dentin Sensitivity, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 12. This study's planned 7 months is close to that.
Counting every sponsor, half of 144 studies reached it within 6 months; a quarter within 3 and three quarters within 10.
