Study Summary
Dental caries (tooth decay) is the most prevalent childhood disease in the world. Multiple interventions are available to treat and prevent caries. The aim of the proposed study is to compare the benefit of silver diamine fluoride (SDF) and fluoride varnish versus fluoride varnish and glass ionomer sealants. This study is a five-year, cluster randomized, pragmatic controlled trial conducted in public elementary schools in New York City.
Primary Outcome
For any participants with any untreated dental caries on teeth at baseline treated with SDF/FV or Glass ionomer/FV to arrest (control) the infection, what is the proportion of subjects that stayed arrested. Differences were compared to the pre-established non-inferiority margin (10%). NOTE: this analysis conducted after COVID-19 suspensions, thus patient enrollment for this outcome is a subset of the total enrollment reported in Participant Flow. It reflects the total enrollment prior to COVID-1
Interventions
- DEVICE Silver Diamine Fluoride
- DEVICE Fluoride Varnishes
- DEVICE Glass Ionomer
