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.

Active Comparator: Silver Diamine Fluoride 38%
Group 1 (SDF 38%) will receive the application of silver diammine fluoride (38% SDF solution) in addition to 5% sodium fluoride varnish to each approximal carious lesion (scores RA1,RA2,RA3) in a posterior tooth (premolar or molar) that is in contact with an adjacent tooth, using super floss, for a duration of 3 minutes under rubber dam isolation.
Drug: Silver Diamine Fluoride 38%
Group 1 (SDF group) subjects will receive the application of silver diamine fluoride (38% SDF solution) in addition to 5% Fluoride varnish to each approximal incipiency, using super floss, for a duration of 3 minutes under rubber dam isolation.
Other Name: 38% SDF
Placebo Comparator: Placebo (Sterile water)
Group 2 (control) will receive the application of sterile water in addition to 5% sodium fluoride varnish to each approximal carious lesion (scores RA1,RA2,RA3) in a posterior tooth (premolar or molar) that is in contact with an adjacent tooth, using super floss, for a duration of 3 minutes under rubber dam isolation.
Drug: Group 2 (Placebo)
Group 2 (Placebo) subjects will receive application of sterile water in addition to 5% Fluoride varnish to each approximal incipiency, using super floss, for a duration of 3 minutes under rubber dam isolation.
Other Name: Sterile Water
- Caries Progression [ Time Frame: 24 months ]comparison of radiographs to determine if there is caries progression in the subjects approximal lesions based on the radiographic examination.
- Incidence of caries in all other teeth in the study subject [ Time Frame: 24 months ]Count for new carious lesions developing over the course of the study period to assess the effect of SDF on preventing the development of early carious lesions
