Introduction: The cariostatic property of glass ionomer cement (GIC) stems from its ability to release fluoride into the oral environment. Recently, zirconia reinforced GIC has been launched which promises the protective benefits of glass ionomer while completely eliminating the hazard of mercury. Aim: To evaluate invitro antibacterial activity and fluoride release from two conventional glass ionomer cements (GC II and GC IX), compomer (Compoglass) and a zirconia reinforced glass ionomer cement (Zirconomer). Materials and Methods: The antibacterial activity of the cement specimens was evaluated against Streptococcus mutans using the agar inhibition test. Zone of inhibition on Mueller-Hinton agar plates was measured after 48 hours. The fluoride release from the cement specimens in ppm were measured at day 1, 7, 14 and 21 using a fluoride ion selective electrode. Data was analysed using one-way and two-way analysis of variance (ANOVA) followed by LSD post-hoc test. A p-value <0.05 was considered statistically significant. Results: Statistically significant largest zone of inhibition was observed with Zirconomer. Also, significant differences were seen in fluoride release of different materials. At all the time intervals maximum fluoride release was observed with Zirconomer and minimum with Compoglass. Conclusion: This invitro investigation has revealed that zirconia reinforced GIC (Zirconomer) had maximum antibacterial activity against S.mutans and fluoride release. [ABSTRACT FROM AUTHOR] |
