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 .
Demineralization around orthodontic brackets bonded with resin-modified glass ionomer cement and fluoride-releasing resin composite.
PURPOSE Enamel demineralization adjacent to orthodontic brackets is one of the risks associated with orthodontic treatment . Glass ionomer cements have been shown to decrease enamel demineralization adjacent to brackets and b and s but do not exhibit bond strengths comparable to resin composites . The purpose of this in vitro study was to compare a fluoride-releasing resin composite versus a resin-modified glass ionomer cement for inhibition of enamel demineralization surrounding orthodontic brackets . METHODS Forty-five teeth were r and omly assigned to 3 groups of 15 teeth . Fifteen were bonded with Concise ( 3 M ) , a non-fluoride-releasing resin composite ( control ) ; 15 teeth were bonded with Light Bond ( Reliance ) , a fluoride-releasing resin composite ; and 15 teeth were bonded with Fuji Ortho LC ( GC Corporation ) , a resin-modified glass ionomer cement . The teeth were placed in an artificial caries solution to create lesions . Following sectioning of the teeth in a buccolingual direction , polarized light microscopy was utilized to evaluate enamel demineralization adjacent to the orthodontic bracket . The area of the lesion was measured 100 microns from the orthodontic bracket and bonding agent . RESULTS MANOVA ( P < .0001 ) and Duncan 's test ( P < .05 ) indicated the resin-modified glass ionomer cement ( Fuji Ortho LC ) and the fluoride-releasing resin composite ( Light Bond ) had significantly less adjacent enamel demineralization than the non-fluoride-releasing resin composite control . However , there was no significant difference between the resin-modified glass ionomer cement and the fluoride-releasing resin composite . CONCLUSIONS Based on the results of this in vitro study , it can be concluded that Fuji Ortho LC and Light Bond exhibit significant inhibition of adjacent demineralization compared to the non-fluoride-releasing control
