This systematic review with meta- analysis found no evidence that either material was superior to the other in the prevention of dental caries .
Thus , both material s appear equally suitable for clinical application as a fissure sealant material
The purpose of this quantitative systematic review was to appraise the evidence on the  caries-preventive effect of glass ionomer cement ( GIC ) in relation to  resin-based fissure sealants .
Fissure sealants: a 4-year clinical trial comparing an experimental glass polyalkenoate cement with a bis glycidyl methacrylate resin used as fissure sealants
The 4-year results of a fissure sealant trial are reported . Glass polyalkenoate and bis GMA sealant were applied to 590 first permanent molar teeth using a half mouth study design in a group of 228 6 - 8-year-old children . Similar cariostasis was observed for the two material s at the end of 4 years despite marked differences in retention . Polyalkenoate cements probably should be regarded as ' fluoride depot ' material s rather than fissure sealants when used in this
