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

2014-07-23 21:08:59 | BioPortfolio

Summary

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.

Description

Community-based, stratified (by location) randomized clinical trial (RCT) to determine the relative efficacy of topically applied fluoride varnish (FV) applications with and without fluoride-releasing glass ionomer (GI) sealants on occlusal surfaces of primary molars in reducing the caries incidence/increment in 3-6 year old children. A 2X2 factorial parallel groups design RCT stratified by study site (one dental and one non-dental location) will be conducted among initially 596 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 Latino 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 done by the trained study dentist to determine caries (precavitated and cavitated) incidence/increment. Children identified as needing dental care will be referred for dental treatment

Medical and Biotech [MESH] Definitions

Fluoride-releasing restorative materials made by the sintering of metal (usually silver) particles to glass ionomer powder. Glass ionomers are fluoride-releasing cements that are not very durable. Sintering of the metal particles is a means of improving those physical properties that will make the glass ionomer cement more durable.

A source of inorganic fluoride which is used topically to prevent dental caries.

Treatment modality for DENTAL CARIES that uses manual excavation method and GLASS IONOMER CEMENTS. Because of its noninvasiveness and no need for expensive equipment and anesthesia it is promoted as an approach in places where dental care is not readily available.

A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries.

Inorganic fluorides of tin. They include both stannic fluoride (tin tetrafluoride) and stannous fluoride (tin difluoride). The latter is used in the prevention of dental caries.
