Physicochemical Properties and Antibiofilm Activity of Tricalcium Silicate Cement and its Association with Cetrimide

Cetrimide (CTR) is a cationic surfactant detergent with antimicrobial and antibiofilm activity. The aim of this study was to evaluate setting time, pH, solubility activity tricalcium silicate cement (TSC) zirconium oxide (ZrO2) its association 0.2 0.4% cetrimide. Initial final times (IST FST) were assessed based on ISO-6876. pH evaluated at periods 1,3,7,14 21 days. Solubility analyzed by weight loss. A modified direct contact test (MDCT) the biofilm Enterococcus faecalis formed bovine root dentin blocks performed, after 6 hours manipulation 15 time. analysis performed UFC mL ­¯¹ counting. data ANOVA Tukey’s tests (α=0.05). Higher IST observed for TSC/ZrO2+CTR in both concentrations than TSC/ZrO2 lower FST TSC/ZrO2+0.4% CTR (p<0.05). On day 1, showed associations During other periods, promoted similar alkalinization (p>0.05). All materials exhibited increased mass. had mass gain highest concentrations, when compared positive control In conclusion, potential promote greater cement, without harming physicochemical properties solubility.
