Resin infiltrate versus compomer as pit and fissure sealants of primary teeth

Abstract

This study designed for the purpose of studying the Resin infiltration system in the form of ICON DMG® versus Compomer in the form of Compoglass Flow Ivoclar Vivadent® regarding their antibacterial effect against streptococcus mutans, clinical retention and their radiographic changes on underlying enamel and dentin when they both used as pits and fissure sealant Methodology: two hundred second primary molars from one hundred children were selected to deliver the two materials in the form of fissure sealant. They arranged in two groups. Both ICON and Compoglass flow applied in contra lateral sides according to the principles of split mouth technique design. The tested materials applied according to the manufacture instructions without modification for their technique of application. Result: Statistical analysis of the microbilogical and clinical data showed that Compoglass flow exhibits superior antibacterial results against streptococcus mutans and less bacterial adhesion were recorded on its surface compared to the -number of bacterial colonies adhered to the fissures sealed with ICON. These results attributed to the fluoride releasing power of Compoglass flow which has an obvious antibacterial action and affect the bacterial community. Meanwhile the statistical analysis of clinical retention scores of both materials reveled superior retention ability of ICON over Compoglass flow along the whole follow up periods. Conclusion: Compomer (Compoglass flow) has superior antibacterial effect against streptococcus mutans superior to resin infiltration (ICON). Resin infiltration (ICON) has a better clinical retention as a fissure sealant than Compomer (Compoglass flow).
