Aim and Objective: To assess the effects of turmeric incorporation on the fluoride release, antibacterial efficacy and physical properties of Glass Ionomer Cement.

Methods: Turmeric was added to GIC at concentration ratios of 0.5% w/w (group II) and 1% w/w (group III) to obtain the test groups. Conventional GIC served as control (group I). The antibacterial activity of the cement specimens were evaluated against Streptococcus mutans using the agar well inhibition test. The fluoride release was evaluated using fluoride ion selective electrode. The physical parameters evaluated were net setting time, shear bond strength and microleakage.

Results: Group II and III showed significantly greater inhibition zones against S.mutans while the control group (Group I) showed only mild inhibition. Similarly group II and group III showed highly significant fluoride release compared to the control group. There was no statistically significant difference in the physical properties viz shear bond strength, microleakage and setting time of the cement between the groups.

Conclusion: Incorporation of turmeric at a concentration of 1% has the potential to enhance the antibacterial activity of GIC as well as fluoride release without compromising on its physical abilities viz shear bond strength, micro leakage and setting time.
