Direct Pulp Capping with Mineral Trioxide Aggregate and Biodentine in Cariously Exposed Molar Teeth: 1-Year Follow-up - An In vivo Study.

Aim: To assess and compare the treatment outcome of direct pulp capping with mineral trioxide aggregate (MTA) and Biodentine, after complete excavation of caries in permanent dentition with a 2-visit treatment protocol. Materials and Methods: Direct pulp capping with white MTA was performed in 70 teeth. Direct pulp capping with Biodentine was also done in 72 teeth. In the subsequent visits after 2 weeks, pulp sensibility tests were attempted in both studied groups. All clinical outcomes were categorized as success or failure. Results: The success rate of the pulp capping procedure in the MTA group at the end of 12 months study was 94.3% in the Class I subgroup and 93.3% in the Class II subgroup. Conclusion: Direct pulp capping with MTA and Biodentine, after pulp exposure during excavation of deep caries could maintain pulp vitality in permanent teeth.

To compare and evaluate the antimicrobial activity of three different root canal sealers: An In Vitro Study.

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.
