Caries incidence and increment [ Time Frame: Every 12 months (plus or minus 1 month) ] [ Designated as safety issue: No ]
Caries increment measured by the amount of change in dmfs index from baseline and caries incidence measured by whether the change in dmfs index increased (ie. change in dmfs >0).
Caries incidence/increment [ Time Frame: Every 12 months (plus or minus 1 week) ] [ Designated as safety issue: No ]
Caries incidence/increment measured by the dmfs index between the two groups of randomized children

Glass Ionomer Sealant and Fluoride Varnish Study to Prevent Early Childhood Caries
Glass Ionomer Sealant and Fluoride Varnish Randomized Clinical Trial

The goal of this project is to conduct a community-based randomized clinical trial to compare the caries prevention efficacy of fluoride varnish applied every six months vs. fluoride varnish applied every six months and fluoride releasing glass ionomer sealants applied annually to the eligible occlusal surfaces of primary molars in 3-6-year-old children.

Community-based, stratified (by location) randomized clinical trial (RCT) to determine the relative efficacy of topically applied fluoride varnish (FV) applications alone vs FV with fluoride-releasing glass ionomer (GI) sealants on occlusal surfaces of primary molars in reducing the caries incidence and increment in 3-6 year old children. A parallel groups design RCT stratified by study site (one dental and one non-dental location) will be conducted among 596 initially 2.5- to 3-year-old children. Those eligible will be randomized to one of 2 groups (FV or GIS+FV) and followed for 36 months. The RCT will take place at two sites serving primarily underserved, minority and low-income populations in Southern California: 1) the dental facility of the San Ysidro Health Center (SYHC) located near the U.S.-Mexican Border serves mainly Latino immigrants, and 2) the Comprehensive Health Center - Ocean View (CHC-OV), in a non-dental setting in close proximity to its dental clinic, which serves Latinos and African Americans. Both sites are part of a consortium of community clinics (SYHC Inc) and are located 15 miles apart from each other.

Annual study dental examinations will be performed by trained, calibrated, study dentists to determine caries (precavitated and cavitated) incidence and increment. Children identified as needing dental care will be referred for appropriate treatment.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
Dental Caries
  • Device: Fluoride Varnish
    Topical application of 0.25mL of fluoride varnish on each dental arch (upper and lower) at baseline and every 6 months.
    Other Name: 3M ESPE CavityShield® single-dose fluoride varnish units
  • Device: Glass Ionomer Sealant

    Fluoroaluminosilicate glass powder and polyacrylic acid liquid are mixed together in a capsule to form the glass ionomer sealant material.

    After toothbrushing and conditioning dental surfaces with 20% polyacrylic acid for 10 seconds, pink-colored fluoride releasing glass ionomer dispensed from a capsule is applied to the occlusal (biting) surface of the molar.

    Other Name: GC Fuji TRIAGE CAPSULE and its conditioner
  • Active Comparator: Fluoride Varnish
    Topical fluoride varnish (FV) applications every 6 months
    Intervention: Device: Fluoride Varnish
  • Experimental: FV + Glass Ionomer Sealants
    Topical fluoride varnish (FV) applications every 6 months, and fluoride-releasing glass ionomer sealants (GIS) placed on primary molars at baseline and annually, as needed
    Interventions:
    • Device: Fluoride Varnish
    • Device: Glass Ionomer Sealant
