Aim of the Study:
The purpose of this study is to compare and analyze the antimicrobial activity of three different root canal sealers.
Materials and Methods:
In this study, the antimicrobial activity of three different root canal sealers were compared against two strains of bacteria
Enterococcus faecalis
which is known to be common isolates of necrotic pulp and endodontic lesions. This test was done at various time intervals (1, 6, 15, and 60 min) using agar diffusion test and direct contact test.
Results:
Bioceramic showed the best antimicrobial activity against
E. faecalis
among the three groups of sealers used. Moreover, the results were statistically analyzed.
Conclusion:
Within the limitations of this study, it can be concluded that Bioceramic sealer showed the best antimicrobial activity followed by MTA Fillapex and Apexit.
To compare and evaluate the volume inadequacy of two different obturation techniques using cone beam computed tomography (CBCT) in an in vitro study. Aim: The aim of this study was to evaluate the adequacy of two obturation techniques, namely, Calamus and Thermafil, via volume rendering method utilizing a three-dimensional (3D) cone beam computed tomography. Results: There is a statistical difference between the Thermafil and Calamus with regard to the adequacy of obturation. The 3D obturating material Calamus has less volume inadequacy as compared to Thermafil. Conclusion: The adequacy of obturation was better with Calamus than with Thermafil. But the research with regard to Calamus and Thermafil still continues in endodontics as a 3D obturating material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
