Abstract Aim The purpose of this in vitro study was to analyze the antimicrobial activity of root canal sealers by using the agar diffusion test (ADT). Methods and Materials Three categories of root canal sealers were included in the study: resin-based sealers (4), zinc oxide-based sealers (3), and calcium hydroxide-based sealers (2). The microbial strains used were: S. aureus (2 strains), C. albicans (2 strains), and E. faecalis (1 strain). Statistical analysis was conducted using a one-way analysis of variance (ANOVA). Tests of differences were analyzed using the Tukey's test with a value of p < 0.05 considered statistically significant. Results The antimicrobial activity of root canal sealers was ranked in descending order as follows: Sealite Regular, Cortisemol, Dentalis KEZ, AH26, Sealapex, Acroseal/Topseal, and Endorez/AH plus. Conclusion Root canal sealers showed different inhibitory effects depending on their types and the bacterial strains tested. Root canal sealers containing formaldehyde and eugenol proved to be effective against the microorganisms studied. Clinical Significance The incorporation of antimicrobial components into root canal sealers may become an essential factor in preventing the re-growth of residual bacteria and control of bacteria re-entry into the root canal system.

Aimed to evaluate the effect of water solubility on chemical properties and surface structure of bioceramic-based (BC-HiFlow and BC-EndoSeqence) compared with resin-based (Adseal) root canal sealers. Fresh mix was inserted into polyethylene mold (n = 10) and subjected to Vicat needle to evaluate the setting time. The set discs were analyzed by Fourier transform infrared (FTIR) spectroscopy then immersed in deionized water for 1, 7, 14 and 28 days. The solubility%, pH changes, released calcium (Ca2+), phosphate (PO43−) and silicon (Si4+) ions were evaluated after each immersion period. The discs were analyzed by scanning electron microscopy/Energy dispersed X-ray (SEM/EDX) before and after solubility test. Although FTIR detected similar composition of both bioceramic-sealers, BC-EndoSequence determined the prolonged setting times. At the end of solubility test, both bioceramic-sealers exhibited significant greater solubility (>3%), alkaline pH (>11) at p < 0.001. Adseal displayed the significant greatest Ca2+ and PO43− released, while BC-HiFlow displayed the significant greatest Si4+ release (p < 0.001). SEM revealed voids and pores on the surface of all tested sealers with the greatest value on Adseal surface. In conclusion, although both bioceramic-sealers had high solubility, BC-Hiflow complied the ISO standard regarding setting time and least surface micropores better than that of BC-EndoSequence.

Aim: The purpose of this study was to compare the antibacterial and antifungal activity of MTA Fillapex with AH 26, AH Plus, and RealSeal root canal sealers. S. aureus, E. faecalis, and C. albicans were used as test microorganisms with the agar-diffusion test (ADT) and the direct contact test (DCT).   Methodology: For the ADT, 48 Mueller-Hinton plates were divided into 3 groups according to the microorganism used. Each group was then divided into 4 subgroups according to root canal sealer. Mueller-Hinton and Sabouraud agar mediums were preferred, and inhibition zones were measured to determine the antimicrobial efficacy at designated intervals. In the DCT, 96-well microtiter plates were used. For each microorganism and each sealer, 8 consecutive wells were prepared vertically on the plate. Microbial suspensions were allowed to directly contact the sealers in each well for 1 hour at 37°C. Subsequently, microbial growth was spectrophotometrically measured at set intervals for the freshly mixed and set forms. Results: A statistically significant difference was found between the tested root canal sealers for antimicrobial effectiveness (p < 0.05). According to the ADT results, all sealers had antimicrobial activity against the tested microorganisms. MTA Fillapex demonstrated satisfying results in the ADT against all microorganisms. In the DCT, MTA Fillapex inhibited bacterial and fungal growth in all freshly mixed and set forms. However, the set forms of AH 26 and AH Plus began to lose their antimicrobial activity on the tested microorganisms after a while. Conclusion: The results showed that the MTA-based root canal sealer MTA Fillapex may be a favorable alternative sealer against bacterial and/or fungal species in clinical practice.   How to cite this article: Türkyılmaz A, Erdemir A.
