Comparative evaluation of antimicrobial efficacy, compressive strength and diametral tensile strength of GIC IX, GIC IX With 1% Chlorhexidine and GIC IX with 1% Cetrimide: An in vitro study

Aim: To determine the antimicrobial efficacy, compressive strength and diametral tensile strength of GIC IX, GIC IX with 1% chlorhexidine and GIC IX with 1% cetrimide Materials and Method: GIC IX was mixed with chlorhexidine and cetrimide powder to produce experimental GIC’s. 10 samples of each of the three groups were prepared for each parameter. Antimicrobial efficacy was evaluated against S.mutans by measuring the zone of inhibition on day 0, 7 and 30 days on blood agar. Compressive and diametral tensile strength were calculated using the universal testing machine after 1hr of setting. Results: Experimental GIC’s had reduced physical properties when compared to GIC. The antimicrobial efficacy was highly improved with the addition of antimicrobials. 1% chlorhexidine produced the best results out of the two experimental GIC’s. Conclusion: GIC containing 1% Chlorhexidine can be alternatively used for pediatric restorations to provide enhanced anticariogenicity.
