简要总结
This pilot trial is randomized, double-blind, and placebo-controlled trial with two parallel arms: an intervention group using silver diamine fluoride (SDF) and a placebo group (control). 60 eligible healthy adults will be enrolled in the study and randomly assigned to one of the two treatment groups. Both groups will receive the traditional preventive measures including cleanings, Fluoride varnish, diet analysis and counseling. Study participants will be followed for one year and caries progression will be radiographically monitored.
详细描述
This pilot study will compare 1) Silver diamine fluoride (SDF) and fluoride varnish to 2) Placebo and fluoride varnish (conventional prevention) in the management of early approximal carious lesions. Early approximal carious lesions refers to decay between teeth, diagnosed with radiographs, not extending more than 1/3 of the way into dentin. Management of early approximal carious lesions refers to halting lesion progression, or encouraging lesion reversal after an early carious lesion is detected.
SDF provides a novel, low-cost intervention option for managing early carious lesions that could potentially bridge the 'gap' between non-operative and operative options; thus, postponing the first placement of a restoration. SDF has been used in arresting carious lesions for more than 100 years. However, SDF has never been tested in the arrest of approximal caries lesions in permanent teeth.
SDF acts to both prevent and arrest tooth decay in multiple ways: 1) it acts on the body of carious lesions by precipitating silver ion into the lesion, thus blocking diffusion pathways for cariogenic acids; 2) it interacts with dental enamel leading to the formation of fluoroapatite crystals making the tooth surface more acid resistant; and 3) the precipitated silver from SDF acts as a bactericidal agent disturbing the formation of cariogenic biofilm.

结局指标
主要结局
Assessment of Radiographic Change in Dental Cavity
时间窗: Baseline, 12 months after blinded treatment with either Silver Diamine Fluoride 38% or placebo (sterile water)
Determine if there is a change in the size of the dental cavity from baseline to 12 months after blinded treatment with either Silver Diamine Fluoride 38% or placebo (sterile water). This measurement will be assessed using radiographic examination to determine if there is either evidence of no radiographic change, radiographic progression, or radiographic regression.
