Context: Success of a periradicular surgery depends on the attainment of a fluid tight apical seal with a well-adapted root-end restoration. Since achieving a dry field is not always possible, the study design was aimed at evaluating the sealing ability of test materials in blood-contaminated field which is usually the clinical scenario. Aims: To evaluate and compare the microleakage of blood-contaminated mineral trioxide aggregate (MTA) and Biodentine as root-end filling materials. Settings and Design: After decoronating, forty recently extracted single-rooted teeth were selected. The canal was enlarged to size #50 using hand files and the rest of the canal was prepared to #80 file at 1 mm increments. The canal was copiously irrigated with 2.5% sodium hypochlorite, ethylenediaminetetraacetic acid, and normal saline between instrument changes. After root-end resection, 3 mm of root-end preparation was done. Subjects and Methods: The root-end filling materials were placed in the following manner. Group 1: Root-end cavity was filled with MTA, Group 2: Root-end cavity was filled with Biodentine, Group 3: Root-end cavity was filled with MTA with blood contamination, and Group 4: Root-end cavity was filled with Biodentine with blood contamination. All samples were incubated for 24 h at 37°C and 100% humidity, and the microleakage was evaluated using a glucose filtration model. Statistical Analysis Used: Statistical analysis was done using an SPSS version 17 software. Data were analyzed with repeated-measures ANOVA and post hoc Bonferroni test. Results: Mean values of microleakage of the different groups in day 1, 4, and 7 were recorded. It was seen that the leakage was increasing with days irrespective of the material and no significant difference in the rate of increase was observed between the different materials. It was also seen that the blood-contaminated samples showed less leakage than the corresponding dry samples except the blood-contaminated Biodentine which showed more leakage on the day 1. However, overall, marginal means indicate no significant difference in the microleakage between materials. Conclusions: The sealing ability of Biodentine showed comparable results with that of MTA in dry and blood-contaminated environments and hence Biodentine can be used as an alternative to MTA for root-end filling procedures in a blood-contaminated environment.
Clinical Relevance to Interdisciplinary Dentistry
- With the movement toward evidence-based dental healthcare, interdisciplinary approach has been gaining ground quickly. Of which, endodontics forms an integral part of interdisciplinary dentistry
- Integrating biochemical analysis with endodontics forms basis to research and is the foundation for a successful dental outcome
- Biodentine shows to be bioactive, which helps to restore the tooth and periradicular structures back to normal form and function.
