Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 12 to 45 with vitamin D deficiency and at least two initial carious lesions.

Probably not a fit

Patients with severe oral health issues, such as periodontitis or those on certain medications, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to compare the effects of vitamin D supplementation and topical fluorides on the progression of initial carious lesions in individuals with vitamin D deficiency. Participants aged 12 to 45 with at least two clinically diagnosed initial carious lesions will be randomly assigned to one of three groups: one receiving vitamin D and oral hygiene instructions, another receiving vitamin D, topical fluorides, and oral hygiene instructions, and a control group receiving topical fluorides and oral hygiene instructions. The study will assess changes in caries detection scores, salivary protein concentrations, and cariogenic microbes over a six-month period. Data will be collected through clinical assessments and laboratory analyses.

Why it matters

Potential benefit: If successful, this study could provide a new approach to preventing dental caries in patients with vitamin D deficiency.

How similar studies have gone: Other studies have shown promising results with vitamin D supplementation in oral health, but this specific approach is relatively novel.
