NCT02591147

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Assessment of Radiographic Change in Dental Cavity

    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.

    Baseline, 12 months after blinded treatment with either Silver Diamine Fluoride 38% or placebo (sterile water)

Study Arms (2)

Silver Diamine Fluoride 38%

ACTIVE COMPARATOR

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.

Device: Silver Diamine Fluoride 38%

Placebo (Sterile water)

PLACEBO COMPARATOR

Group 2 Placebo (control) will receive the application of sterile water (placebo) 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.

Device: Group 2 (Placebo)

Interventions

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.

Also known as: 38% SDF
Silver Diamine Fluoride 38%

Group 2 (Placebo) subjects will receive application of sterile water (placebo) in addition to 5% Fluoride varnish to each approximal incipiency, using super floss, for a duration of 3 minutes under rubber dam isolation.

Eligibility Criteria

Age21 Years - 64 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Presence of at least one approximal caries lesion (scores RA1, RA2, RA3 according to the ICCMS radiographic scoring system) in one of the posterior teeth (premolars and molars) presented with full contact with the adjacent tooth.
  • All the surfaces eligible for this study will be included.

You may not qualify if:

  • The approximal lesion detected in the radiograph has advanced dentine lesion (RB4, RC5, or RC6)
  • or is adjacent to a lesion that is either filled or will receive a filling at the time of enrollment.
