Trial Outcomes & Findings for The Effect of Silver Diamine Fluoride (SDF) on Bacteria Involved in Root or Cervical Carious Lesions (NCT NCT02953886)

NCT ID: NCT02953886

Last Updated: 2018-09-28

Results Overview

Using human oral microbiome identification using next-generation sequencing (HOMINGS), change in the total bacterial composition of all subjects was measured by the difference of the number of bacteria count from baseline to one month after SDF application.

Measure
Silver Diamine Fluoride (SDF)
Application of Silver Diamine Fluoride (SDF) to root or cervical carious lesions (cavities). Collection of plaque pre- and one month post-SDF application. Silver Diamine Fluoride (SDF): No caries removal will take place. Bacterial samples will be collected using Gracey curettes at the initial visit before application of SDF and one month after. The tooth will be dried and SDF will be placed on the carious dentin until saturated. Excess will be blotted dry with a cotton pellet

Change in Bacterial Composition Before and One Month After SDF Application to Root or Cervical Caries Lesions
Baseline
1890087 bacterial count
Change in Bacterial Composition Before and One Month After SDF Application to Root or Cervical Caries Lesions
One month after SDF
1959306 bacterial count

PRIMARY outcome

Timeframe: One month

Caries were examined for hardness or softness before and after SDF application. The change in the texture was examined after one month of SDF application the change from soft to hard is noted below.

SECONDARY outcome

Timeframe: One month

Each subject was asked if they were concerned with the appearance of the tooth that SDF was applied too. They were also asked if they wanted the study tooth to be filled with a tooth color filling.
