Two-year clinical evaluation of flowable composite resin containing pre-reacted glass-ionomer

Flowable resin restoration is a useful technique for children with caries. However, when composite resin restoration is performed by an inexperienced clinician, improper placement technique can lead to such problems as poor adaptation, voids and secondary caries formation. In this study, we examined fluoride release from surface of pre-reacted glass-ionomer (S-PRG) fillers containing flowable resin, termed flowable giomer. Beautiful Flow F02 showed a higher amount of fluoride released during the experimental period as compared with the other flowable resins tested. We also used that flowable giomer for Class I, II, and III restoration procedures in 95 primary teeth and 85 permanent ones, and evaluated the results using USPHS/Ryge criteria. Beautiful Flow F02 showed good clinical properties equal to those of conventional resin restorations previously reported. Our results indicate that a flowable giomer is useful for primary and permanent teeth esthetic restoration, which is important for the prevention of secondary caries and adhesion of bacterial flora on resin surfaces.
