Abstract :Backrounds: This study aimed to evaluate the antimicrobial activities of glass ionomer luting cements modified with chlorhexidine diacetate. Methods: Chlorhexidine diacetate (CXD) was incorporated into glass ionomer luting powder at 0 %, 1 %, 2 %, 3 % concentration and 120 round-shaped samples were prepared. Antimicrobial properties against Streptococcus mutans (S. mutans), Enterococcus faecalis(E. faecalis), and Candida albicans (C. albicans) were assessed with MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] and Cristal Violet Assay. Biofilms on samples were also observed by Scanning Electron Microscopy. One-way ANOVA and Tukey Tests were used for statistical analysis. Results: The highest amount of antimicrobial activity was found in samples with 3 % added CXD. The proportion of viable pathogens were reduced significantly with the addition of 2 % and 3 % CXD (p < 0.05). A noticeable reduction of S. mutans amount was seen with incorporation of 3 % CXD (p < 0.05). S. mutans and C. albicans were inhibited significantly by all the samples when compared to control groups. Conclusions: Addition of 2 %- 3 % CXD to glass ionomer luting cements increased the antimicrobial properties. As, microorganisms’ growth rate was inhibited in 3% CXD group, CXD added glass ionomer luting cement can be suggested in endodontically treated teeth, in high caries-risk patients, also in immunocompromised patients.
