Effect of Vitamin D Supplementation on Salivary Biomarkers; Certain Proteins and Cariogenic Oral Microbiome for Medical Management of Dental Caries: A Randomized Controlled Trial

Overview

The goal of this clinical trial is to compare the treatment effect of vitamin D supplementation and topical fluorides in the population having vitamin D deficiency and Initial Carious Lesions (ICL) on the progression of ICL in teeth. This study aims to observe the changes in the International Caries Detection and Assessment System (ICDAS) scores, the concentration of salivary proteins, and cariogenic microbes, six months after the interventions. * Group A will get vitamin D supplements and oral hygiene instructions (OHI). * Group B will get vitamin D supplements, topical fluorides, and OHI. * Group C (Control), the vitamin D sufficient group will get topical fluorides and OHI.

Detailed description

The study investigator will conduct a multi-centered randomized clinical trial in the outpatient department of Operative Dentistry, in three units of Dow University of Health Sciences (DUHS), with parallel treatment assignment to an experimental, active comparator, and control groups. The investigator will recruit study participants aged 12 to 45 at moderate risk of dental caries, specifically those with vitamin D deficiency. Additionally, participants must have at least two clinically diagnosed teeth with initial carious lesions (ICL). Each participant will be enrolled for six months in this trial.

The investigator will obtain data on vitamin D deficiency from Dow Diagnostic Laboratory. Dental caries risk will be assessed using a caries risk assessment (CRA) form, while ICL will be evaluated through the International Caries Detection and Assessment System (ICDAS) scores. The investigator will collect the samples of participants' saliva to analyze salivary proteins using the enzyme-linked immunosorbent assay (ELISA), and cariogenic microbes through polymerase chain reaction (PCR).

Participants will be assigned to one of three groups randomly:

* Group A participants will be vitamin D deficient with caries, receiving vitamin D supplements and Oral hygiene instructions (OHI). * Group B participants will be vitamin D deficient with caries, receiving vitamin D supplements, topical fluorides, and OHI. * Group C participants will be vitamin D sufficient to be considered as controls for comparison, receiving fluoride application and OHI.

The investigator will assess study outcomes by observing changes in ICDAS scores, salivary protein concentrations, and count of cariogenic bacterial species (Streptococcal mutans and Lactobacilli).

Interventions

  • Dietary supplement Vitamin D supplements along with behavioral modification
    Vitamin D soft gel capsules of 50,000 IU/week for two months followed by a maintenance dosage of 5000 IU/day for one month. Behavior modification for dental caries with standard instructions of brushing teeth twice daily with regular fluoridated toothpaste and diet counseling.
  • Combination product Topical fluoride application and Vitamin D supplements along with behavioral modification
    Professional topical 5% sodium fluoride gel application for 5 minutes on the teeth having ICL. Behavior modification for dental caries with standard instructions of brushing teeth twice daily with regular fluoridated toothpaste and diet counseling. Vitamin D soft gel capsules of 50,000 IU/week for two months followed by a maintenance dosage of 5000 IU/day for one month. Behavior modification for dental caries with standard instructions of brushing teeth twice daily with regular fluoridated to
  • Procedure Topical fluoride application along with behavioral modification
