This study confirms the likelihood that remnants of high-viscosity glass-ionomer sealant material are retained and block the deeper parts of pits and fissures even after the sealant appears to have disappeared clinical ly , exercising their carious lesion preventive effect
OBJECTIVES Resin composite sealants are retained longer than low-viscosity glass-ionomer sealants .
Nevertheless , a systematic review showed that there is no evidence that resin composite sealants are superior to low-viscosity glass-ionomers in preventing dentine carious lesion development .
This case study aim ed to investigate reasons for this .
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
