Sažetak
Context: The addition of antimicrobial agents can improve the antimicrobial characteristics of the material, which is desirable for root canal sealers. Aims: The aim of this study is to determine the effect of the addition of benzalkonium chloride and cetylpyridinium chloride in three commercial root canal sealers. Settings and Design: Three different root canal sealers have been used: EndoRez, N2, and Apexit Plus. The samples were prepared by mixing the components according to the manufacturers’ guidelines and adding 2% in weight of the antimicrobials to the newly mixed cement. Materials and Methods: The paste was placed in molds and stored in an incubator (37°C, 24 h). The samples were then stored in 5‑ml distilled water (1 day, 1 week, and 1 month). The impact of the antimicrobials on the solubility of the sealers, the release of chloride ions (Cl− ), and the pH value was examined. Statistical Analysis Used: Analysis was done using one‑way analysis of variance and the post hoc Tukey’s honestly significant difference test. Results: Chloride ions are present in storage media with EndoRez, N2, and Apexit Plus samples(without antimicrobials) following all tested storage intervals. The addition of the antimicrobials increased the release of chloride ions. Endodontic cements without addition of antimicrobials show an increase in weight after 1 month. The highest pH value is measured in Apexit Plus samples. The solutions in which N2 samples(with and without addition of antimicrobials) were stored did not significantly change their pH, while in EndoRez solutions, a significant decrease of the pH value after the 1st week was measured. Conclusions: The addition of antimicrobials might lead to improved characteristics of the root canal sealers.
