The evidence suggests that RM-GIC is associated with a higher reduction of demineralization in adjacent hard tooth tissue than composite resin without fluoride .
No difference was found when RM-GIC was compared with fluoride-containing composite resin .
RM-GIC showed efficacy in reducing demineralization .
UNLABELLED The purpose of this systematic review was to quantitatively find out whether resin-modified glass-ionomers ( RM-GIC ) , in comparison to fluoride-containing composite resin and composite resin without fluoride , are associated with a more effective reduction of demineralization in hard tooth tissues under caries challenge .
Effect of Microleakage and Fluoride on Enamel-Dentine Demineralization around Restorations
There is no consensus about an association between microleakage and secondary caries , especially considering the presence of fluoride ( F ) at the tooth/restoration interface . Thus , a r and omized , double-blind , crossover study was carried out to evaluate in situ the effect of microleakage on caries around enamel-dentine restorations in the presence of F from dental material s or dentifrice , either alone or in combination . In 4 phases of 14 days each , 14 volunteers wore palatal devices containing dental slabs restored with composite resin ( CR ) or resin-modified glass ionomer cement ( GI ) . Restorations were made without leakage ( L– ) , following the recommended adhesive procedures , or with leakage ( L+ ) , in the absence of adhesive procedures . Plaque-like biofilm ( PLB ) was left to accumulate on the restored slabs , which were exposed extraorally to a 20 % sucrose solution 10 × /day . The volunteers used a non-F ( NF ) or an F ( FD ) dentifrice 3 × /day , depending on the experimental phase . No differences were found between L+ or L– restorations ( p > 0.05 ) . Higher demineralization in both enamel and dentine around CR restorations was observed under NF ( p < 0.05 ) . F concentration was higher in the fluid of PLB exposed to FD or formed onto GI restoration ( p < 0.05 ) . These results suggest that while microleakage does not affect caries development , GI or FD may maintain increased F levels in the PLB , thereby decreasing caries progression
