Comparison of Antimicrobial Efficacy and Physical Properties of Antibiotic-Modified, Propolis-Added, and Conventional Glass Ionomer Cement

A BSTRACT Objective: To evaluate the antimicrobial efficacy and physical properties of antibiotic-modified GIC, propolis-incorporated GIC, and conventional GIC. Study Design: An antibiotic mixture containing ciprofloxacin, metronidazole, and doxycycline and propolis tincture were mixed with GIC to obtain two study groups and Fuji IX as a control group. Antibacterial action, fluoride release, and physical properties were evaluated. Results: Addition of antibiotics and propolis to GIC increased its antimicrobial action without negatively modifying physical properties of conventional GIC. Conclusion: Hence, the incorporation of antibiotics and propolis into GIC provided an acceptable combination of properties.
