Fissure Sealing with Resin Modified Glass Ionomer-A One-Yar Clinical Study

Abstract

Purpose: The purpose of this study was to evaluate the retention rate and caries preventive effect of a single application of light cured resin modified glass ionomer (Vitremer, 3M) in pits and fissures and compare it with a resin sealant ( Delton, Dentsply). MethOds: Fifty-nine children with newly erupted first permanent molars (age between 5 - 7 years) were selected for this study. A total of 160 first permanent molars were sealed. Resin sealant was applied on one side of molars and RMGI to the corresponding molars on the opposite side. The sealants were placed equally on both sides of patient's mouth.The teeth were checked every three months for sealant retention and presence of caries. Results: The results showed that the complete retention rate of Vitremer was 37.5 % at three months, 37.4% at six months, and 33.3 % at twelve months. There were twel ve carious molars in the Vitremer group at twelve months. The complete retention rate of Delton was 55 % at three months, 46.2% at six months, and 33.3 % at 12 months. There were six carious molars In Delton group at twelve months. There was no ;ignificant difference of complete retention rate between Delton and Vitremer except at the three-month recall. There was also no significant difference in caries development between both groups. Conclusion: The caries preventive effect and retention rate of Vitremer was comparable to Delton if used as a fissure sealant. Fluoride release from sealant is helpful, but not the primary factor of caries prevention in pits and fissures. Retention seems to be the most important factor for caries prevention.
