ABSTRACT
When evaluating the antimicrobial effect of endodontic sealers it is important to study the variation of pH, since this is one of the properties that may inhibit the microbial growth and influence biocompatibility. The aim of this study was to evaluate the capacity of several endodontic sealers without calcium hydroxide to modify the pH of the solution in which they were immersed. The sealers used were: Endomethasone C-Septodont (EC), Bio Seal-Ogna (BS), Diaket-Espe (D), Procosol-StarDental (P), AH26-Dentsply (AH), Ketac Endo-Espe (KE), AHPlus-Dentsply (AHP), Endion-Voco (E), Endomethasone-Septodont (EM), EZ Fill-Essential Dental Systems (EZ). Samples of each material were placed in tubes with phosphate saline solution (PBS). The pH was determined at 2, 5, 12, 20, 30, 60, and 90 days. A tube with solution alone was taken as control. Statistical analysis of the results was performed by ANOVA. Material, sample, time and material-time interaction elicited statistically significant differences (p < 0.05). The variation of pH produced by immersion of endodontic sealers depends on the composition of the material.
