About

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

Full 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.
