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 .
Comparison of glass-ionomer and resin-based fissure sealants: a 2-year clinical trial.
In recent years , the interest in the use of glass-ionomer material s as fissure sealants has increased . The aim of this study was to compare the retention and caries-preventive effect of glass-ionomer ( Fuji III ) and resin-based light-cured ( Delton ) fissure sealants .  Three health center dentists applied the sealants to 166 children ; glass-ionomer sealants  on one side and resin-based sealants on the contralateral side of the mouth . After 2 yr , one pair of molar teeth in the mouths of 151 children was compared . Twenty-six percent of glass-ionomer and 82 % of resin-based sealants were totally present ( P < 0.001 ) . During the 2 yr , in both groups 4.6 % of the sealed surfaces became carious . The results show that the retention of glass-ionomer sealants  is markedly inferior to the resin-based sealants . In this study , however , no difference in caries increment on the sealed surfaces was observed . This may be due to the different mechanism of caries prevention for the sealant material s , or to the overall low caries activity of the participants
The overall outcome of the computed data sets suggest no difference between the caries-preventive effects of GIC- and resin-based fissure sealants .
