Conclusion It seems that the use of flowable composite as a fissure sealing material can slightly increase the retention rate of sealants compared with conventional resin-based sealants
Objectives The aim of this systematic review and meta- analysis was to evaluate fissure sealant retention in clinical studies in which investigators used flowable composites as pit and fissure sealants compared with conventional resin-based pit and fissure sealants .
Clinical evaluation of a medium-filled flowable restorative material as a pit and fissure sealant.
This clinical study evaluated the retention rate and caries protection of a medium-filled ( 46 % volume ) flowable restorative material ( CuRay-Match , OMNII Oral Pharmaceuticals , West Palm Beach , FL 33409 , USA ) compared to an unfilled sealant ( Delton , Dentsply Caulk , Milford , DE 19963 , USA ) . Using a half-mouth design , sealants were applied on r and omly assigned caries-free first and /or second permanent molars of 32 children ranging in age from 6 - 11 years . A total of 118 teeth were etched , dried and sealed . Teeth were evaluated at one , six and 18-month intervals . After one month , 52 teeth sealed with unfilled sealant were intact compared with 46 sealed with a medium-filled resin , and after six months , 36 teeth sealed with an unfilled sealant were intact compared with 27 that were sealed with a medium-filled resin . After 18 months , 29 teeth were still fully sealed with an unfilled sealant , whereas 18 were sealed with a medium-filled resin . The difference between the two groups was not statistically significant . Regarding caries development , four teeth sealed with a medium-filled material and five teeth sealed with an unfilled sealant were decayed after 18 months . These results indicate that a medium-filled flowable restorative material did not perform better in retention rate and caries increment when compared to an unfilled conventional sealant . However , the effect of the additional techniques , such as the use of bonding agent and fissurotomy on retention rates should be evaluated in further studies
