Brief Summary:
This trial is a Phase III, multisite, randomized, placebo-controlled trial, with two parallel groups. The groups are SDF or placebo and they are applied every 6 months. The primary hypothesis of the trial is that SDF is better than placebo for stopping cavities with dentin exposed in baby teeth when assessed at 6 months after initial application.
Detailed Description:
This trial is a phase III, multicenter, randomized, placebo-controlled superiority trial, with two parallel groups (placebo vs. SDF applied to cavitated lesions) involving a total of 1144 children with the primary outcome assessed at 6 months after initial treatment.
One thousand one hundred forty four children, 12-71 months of age, from early childhood education programs, such as Head Start centers, Early Head Start centers, and equivalent city/state subsidized preschool programs, or children attending dental clinics associated with the clinical trial sites, will be randomized, in two cohorts. Trial visits will occur at baseline, 3 months, 6 months, and 8 months. SDF/placebo will be applied at baseline and 6 months. Parents/legal guardians will be called 24 to 48 hours after the SDF/placebo application to assess adverse events and unanticipated problems and in-person visits for safety exams will be available for all child participants approximately 24 to 48 hours after SDF/placebo application. This visit could happen before or after the 24- to 48-hour call with the parent or legal guardian, but every attempt will be made so that the call occurs prior to the 24- to 48-hour visit. Additionally, intermediate contacts at 1.5 months, 4.5 months, and 7 months will occur to determine if the child needs an additional visit to assess pain, lesion progression, etc. and to maintain contact with the participant.
Randomization to SDF application (treatment) or placebo (control) will be at the participant-level; all teeth within a participant that meet the inclusion criteria will receive the same trial product. Both treatment and control will be dispensed from identical unit-dose ampules coded and labeled to ensure masking of all trial personnel. The number of ampules required to treat all carious lesions in the participant's mouth will be recorded. No caries removal will be performed. Teeth will be cleaned with a toothbrush and will be dried with cotton/gauze, and the solution will be painted on the dentin of each targeted cavitated lesion using a standardized applicator. Following application, the tooth will be blotted dry with gauze.
At each clinical visit International Caries Detection and Assessment System (ICDAS) examinations, including cavitated lesion hardness assessments, soft tissue assessments and questionnaires on dental discomfort, family impact and treatment satisfaction and acceptability will be collected.
