Local active vitamin D injections to speed upper canine movement

Effect Of Local Use Of 1,25 Dihydroxycholecalciferol on Rate of Canine Distillization: A Split Mouth Randomized Control Trial

Phase 1 Interventional Foundation University Islamabad · NCT07479290

This will try injecting active vitamin D near upper canine teeth to see if it speeds their retraction in people having bilateral maxillary first premolar extractions.

What this trial studies

This Phase 1 split-mouth randomized controlled trial will enroll 30 patients scheduled for bilateral maxillary first premolar extractions. Each patient's maxillary arch will be randomized by side: the study side will receive injections of 1,25-dihydroxycholecalciferol in DMSO and the control side will receive plain DMSO placebo at extraction, one month, and two months. Canine retraction distance will be measured on dental impressions at each timepoint to compare movement between sides. The approach tests whether local active vitamin D can accelerate tooth movement without systemic administration.

Who should consider this trial

Good fit: Adults with permanent dentition who are Class I or II malocclusion and scheduled for bilateral maxillary first premolar extractions with at least 5 mm of extraction space.

Not a fit: Patients with craniofacial deformities (for example cleft lip/palate), metabolic bone disease or diabetes, pregnant or lactating women, or those not undergoing the required premolar extractions would not be expected to benefit from this intervention.

Why it matters

Potential benefit: If successful, this could shorten the time needed for canine retraction during orthodontic treatment and reduce overall treatment duration.

How similar studies have performed: Animal studies and small clinical reports of local biological agents, including active vitamin D, have shown increased bone turnover and accelerated tooth movement, but strong clinical evidence in humans is still limited.
