Clinical Trial Summary

This study investigates whether 1) Silver diamine fluoride (SDF) application using Super Floss can arrest and/or reverse initial interproximal caries on primary molars and 2) whether SDF applied with Super Floss is more effective in arresting or remineralizing initial interproximal lesion in comparison to SDF applied without Super Floss or fluoride varnish applied alone.


Clinical Trial Description

Interproximal carious lesions are challenging to control and arrest due to difficulty reaching the contact area (in between teeth), limited salivary access, and poor flossing compliance in children and adolescents when flossing themselves. The vast majority of caries observed in children ages 5 to 10 are on interproximal surfaces. Silver diamine fluoride (SDF) is a topical medicament touted as a very safe and noninvasive alternative and/or adjunct to topical fluoride treatment or restorative treatment to halt the progress ("arrest") of caries. SDF has been shown to remineralize ("reverse") demineralized enamel or dentin, inhibit collagenases to protect dentin collagen from destruction, and have bactericidal properties to cariogenic bacteria including streptococcus mutans. Normally, SDF is applied with a microbrush directly on an exposed carious lesion, but due to difficulty reaching interproximal carious lesions, an absorbent type of floss such as Super Floss has been proposed as a delivery method for SDF application. The purpose of this study is to investigate whether 1) SDF application using Super Floss can arrest and/or reverse initial interproximal caries on primary molars and 2) whether SDF applied with Super Floss is more effective in arresting or remineralizing initial interproximal lesion in comparison to SDF applied without Super Floss or Fluoride varnish applied alone. The study population includes healthy children, aged 3-12, with initial interproximal decay on deciduous molars identified by radiographs. In this study, initial decay is defined as radiographic decay within enamel or extending to the dentin-enamel junction based on International Caries Classification and Management System (ICCMS). Any eligible participant will be randomly allocated to one of three treatments: Fluoride varnish (Control) application alone versus SDF application without Super Floss (Control) versus SDF application with Super Floss (Intervention), which will be applied at the initial visit. At 3, 6, and 12 months, the participants will return for reapplication of their respective treatments. At the 6 month and 12 month mark, bitewing radiographs will be taken to determine status of the interested lesion(s). If a lesion progresses beyond the outer 1/3 of dentin, then the patient will be withdrawn and recommended routine restorative dental treatment. If a lesion arrests or reverses, then the current treatment will continue until end of study duration (12 months) and re-evaluated. A statistician will be assisting us with descriptive statistics, cluster-adjusted chi-squared test, and other statistics to determine if any correlation exists. ;
