Brief Summary:
The study will compare bacteria levels in cavities before and after silver diamine fluoride (SDF) treatment.

Condition or disease Intervention/treatment Phase
Caries Device: Silver Diamine Fluoride (SDF) Phase 4

Detailed Description:
To assess the effect of silver diamine fluoride (SDF) treatment on microorganisms present in root caries or cervical lesions by collecting microbial deposits before and 1 month after SDF application. Bacterial samples will be collected from 20 adult subjects at the initial visit before application of SDF and one month after. At the 1 month recall, examination for caries arrest will be performed. All 40 bacterial samples will be sent to the Forsyth Institute to verify bacterial composition using HOMINGS technology.

Arm Intervention/treatment
Experimental: 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.
 Device: 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
Other Name: Silver Dental Arrest


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in Bacterial Composition Before and One Month After SDF Application to Root or Cervical Caries Lesions [ Time Frame: baseline, One month after SDF ]
    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.

  2. Caries Arrest of Teeth Measured by Change in Dentin Texture (Soft, Hard) [ Time Frame: 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 Measures :
  1. Patient Assessment of Appearance of Treated Tooth (Concern With the Appearance of Study Tooth, Desire for the Study Tooth to be Filled) [ Time Frame: 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.
