The overall outcome of the computed data sets suggest no difference between the caries-preventive effects of GIC- and resin-based fissure sealants .
Background This article constitutes a partial up date of the original systematic review evidence by Yengopal et al. from 15 January 2008 ( published in the Journal of Oral Science in 2009 ) with primary focus on research quality in regard to bias risk in trials .
Its aim is to up date the existing systematic review evidence from the English literature as to whether caries occurrence on pits and fissures of teeth sealed with either GIC or resin is the same .
Clinical and antibacterial effectiveness of three different sealant materials.
PURPOSE The aim of this work is to study and compare the retention rate , caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant . METHODS Forty-five children aged 7 - 10 years with newly erupted lower first permanent molars were r and omly divided into three equal treatment groups . Group I : sealed by a conventional resin sealant ; Group II : sealed by resin modified glass ionomer ( RMGI ) ; and Group III : sealed by flowable composite .  Retention and caries status of the sealed teeth were recorded after 1 month , 6 months , year and 2 years . In addition , Streptococcus mutans counts were assessed at baseline , 1 day , 1 month , 6 months , 1 year and 2 years after sealant application . Data were analyzed by Fisher exact , chi-square and ANOVA tests . RESULTS Group III and Group I showed significantly higher retention rates than Group II fissure sealant ( p<0.05 ) . There were no differences of the caries-preventive effects between the tested sealant material s throughout the duration of the study . Streptococcus mutans counts were significantly lower in group II compared to group I or group III up to 6 months of the study ( p<0.05 ) . After 1 year of the study the differences of Streptococcus mutans counts were not significant ( p>0.05 ) . CONCLUSION This study indicated a lower retention of RMGI compared to flowable composite and resin sealant without significant difference in caries prevention or long-term bacterial inhibition
The overall outcome of the computed data sets suggest no difference between the caries-preventive effects of GIC- and resin-based fissure sealants .
