Clinical; Evaluation of a Resin-modified Glass Ionomer Sealant under Simple Exclusion of Moisture for Caries-preventive Effects on Immature Permanent First Molars

Abstract

Resin-modified glass ionomer sealant (RMGI) (Fuji III LC®w) as applied under simple exclusion of moisture in 54 children who had been under regular dental care since the primary dentition stage (A group) and 46 children who started since the mixied dentition stage (B group), and the clinical results were investigated. As for the results, the clinical examination showed the cariostatic rate of 98.1% in A group and 98.3% in B group which were under care for 4.6 years and for 5.5 years after application of RMGI, respectively. In order to maintain the high caries-preventive rates, this results indicated the need for both additional application to unerupted fissures and another preventive procedures at the regularly dental check up. In the case of fissure sealant by this material, it was shown that there was no problem, even if it is done under simple exclusion of moisture.
