Condition(s) targeted: Dental Caries

Intervention: Sodium Fluoride (Drug); vancomycin hydrochloride (Drug); vancomycin hydrochloride (Drug); chlorhexidine digluconate (Drug)

Phase: N/A

Status: Completed

Sponsored by: Universidade Federal do Ceara

Summary

The aim of the present study was to compare salivary MS levels in four different groups of children with caries, that have been submitted to intraoral topical treatment with either 1,23% sodium fluoride, 1% chlorhexidine, 3% or 10% vancomycin, during 6 consecutive days. This clinical trial was designed to test two different hypotheses. First, that topical vancomycin would be more effective than chlorhexidine and sodium fluoride in salivary MS reduction. Secondly, a 6-day antimicrobial treatment with either one of these agents would produce a long lasting MS suppression, dispensing repeated antibacterial treatments.

Clinical Details

Official title: Sodium Fluoride, Chlorhexidine and Vancomycin Effect in the Inhibition of Mutans Streptococci in Children With Dental Caries: a Randomized, Double-Blind Clinical Trial

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Prevention

Primary outcome: Salivary mutans streptococci levels prior to treatment, on the last day of treatment (day 6), two weeks after day 1 and 30 days after day 1.

Secondary outcome: Number of new carious lesions within the different study groups 12 months after treatment discontinuation.

Detailed description: The present study aimed to compare the effect of sodium fluoride, chlorhexidine and vancomycin on salivary mutans streptococci (MS) levels, on a double-blind, randomized clinical trial. Sixty-nine healthy volunteers, aged 4-8 years, with at least one active carious lesion and no previous history of allergies were selected to participate in the study. A gel formulation containing 1. 23% sodium fluoride, 1% chlorhexidine, 3% or 10% vancomycin was topically administered to the dentition every 24 hours, during 6 consecutive days. Salivary MS levels were measured at baseline (D1), on the 6th (D6), 15th (D15) and 30th day (D30). For microbiological analysis, MSB agar medium was used.
