Abstract

Objective: To compare the effect of Maleic acid and Irritrol (combination of Chlorhexidine & Ethylenediaminetetraacetic acid) irrigation on the sealing ability of Biodentine when used as root-end filling material. Material and Methods: Thirty single-rooted human premolars were subjected to standardized root canal instrumentation and were irrigated with 2.5% Sodium Hypochlorite (NaOCl) after each instrument change. Apical root resections were done by removing 3 mm of the apex at a 90° angle to the long axis of the root with a diamond bur. The root end cavity preparation was done using ultrasonic tips at a low power setting under water coolant. They were randomly divided into 3 groups (n=10). Group 1 was irrigated with 7% Maleic acid, Group 2 was irrigated with Irritrol, and Group 3 was irrigated with 0.9% Saline (Control). Then, the root end cavities of all the samples were restored with Biodentine and were subjected to leakage analysis using a glucose filtration test. The mean values for each group were calculated and the obtained data was statistically analysed using ANOVA with post-hoc Tukey’s test, ANOVA with post-hoc Games-Howell test and repeated measures ANOVA with post-hoc Bonferroni test. Results: The specimens irrigated with Irritrol showed least microleakage as compared to 7% Maleic acid and 0.9% Saline. Conclusion: A regimen involving irrigation of the root-end cavity with Irritrol followed by root-end filling with Biodentine can improve the apical seal.
