To compare the resistance against bacterial micro leakage offered by Zinc Oxide Eugenol sealer, Apexit, AH plus, AH 26 against Enterococcus Faecalis along obturated root canals with failed coronal seals
Journal Title: Scholars Journal of Dental Sciences - Year 2015, Vol 2, Issue 6
Abstract
Abstract: Coronal micro leakage is one of the reasons for failure of endodontic treatment. Methods to measure coronal micro leakage have included dyes, radioisotopes, fluid filtration, and microorganisms. 52 extracted human lower premolars were previously collected and were stored in saline till it was required for the study, and were divided into 5 groups n=10 .Root canal treatment was done using conventional method and obturation was done using different sealer for each specific group. Group 0 : Control Group (teeth obturated without using a sealer) Group 1:Zinc Oxide Eugenol, Group 2: AH Plus, Group 3: AH 26, Group 4: Apexit. Following this split chamber model was prepared and the samples were labelled and arranged in a test tube stand and incubated at 37oC. Bacterial inoculation was done and any turbidity in the lower chamber was recorded according to the assigned groups for the specific day and staining was done every day. In results the AH 26 (GROUP 3) performed better than AH PLUS (GROUP 2), APEXIT (GROUP 4) and ZOE (GROUP 1). In conclusion AH 26 showed maximum resistance against E. Faecalis. Keywords: AH 26, E. Faecalisresistance, Endodontic sealers, Split Chamber Model.
