Trial Outcomes & Findings for The Antibacterial Effect of Nanosilver Fluoride on Primary Teeth (NCT NCT05221749)

NCT ID: NCT05221749

Last Updated: 2023-08-18

Results Overview

Measuring the percent change in prevalence of cariogenic bacteria using standard microbiological culturing methods, outcome assessment will be done using colony forming units (CFU) from every sample collected. Samples will be collected immediately before application of the intervention (baseline) and one month after the intervention application (1 month follow-up). The CFU counts will be used to calculate the percentage change in bacterial prevalence which will be used for assessment and reporting results

PRIMARY outcome

Timeframe: 1 month

Population: This investigation and consequent analysis were not conducted.

A statistical analysis will be done to correlate between the change in number of available cariogenic bacteria from baseline to 1 month (measured in colony forming units) and the caries activity of the lesion (as specified by the international caries detection and assessment system (ICDAS II) criteria.
