COMPARATIVE EVALUATION OF FLUORIDE RECHARGE OF FLUORIDE RELEASING DENTAL MATERIALS BY FLUORIDATED DENTIFRICE : AN IN VITRO STUDY

Introduction: Fluoride releasing dental materials releases maximum fluoride within twenty four hours which reduces thereafter.Ifwe could recharge fluorideon the daily basis,the caries preventive effect from fluoride releasing dental materials can be prolonged. Aim and Objectives : The present study is undertaken to compare and evaluate fluoride recharge of fluoride releasing dental materials by fluoridated dentifrice. Materials and Method : Materials used in this study are GC Fuji Type IX,Fuji Plus,Zirconomer Improved,Beautifil II LS. All restorative materials were mixed according to manufacturers instruction and standardized test pellets were made using autoclaved instruments in sterile plastic moulds. These test pellets were divided in various groups and brushed with fluoridated dentifrice accordingly . Results were evaluated statistically using Post Hoc testandANOVA and correlation coefficient for which regression lines were drawn. Result: The mean fluoride release and rechargewas maximum in Zirconomer Improved, followed by GC Fuji Plus ,then by GC Fuji Type IX and least by Beautifil II LS. Conclusion: Daily recharge of fluoride releasing dental materials with fluoridated dentifrices is recommended to increase the cariostatic effect .
