Abstract

Background: Bacterial infection is widely known cause of apical periodontitis. Failure of conventional root canal treatment indicates the periapical surgery, this procedure requires root end resection. For the long term success of periapical surgery, root end filling materials are used.
To compare the push-out bond strength of Portland cement, ProRoot MTA and Biodentine used as root-end filling materials using Universal Testing Machine.
Materials and Methods: From the middle part of each root, three dentinal slices were made to produce 93 slices which were divided into 3 groups. In Group A: ProRoot MTA, In Group B: Biodentine and In group C: Portland cement were used and were further divided in subgroups based on soaking time in PBS solution i.e. 24hrs and 7 days before assessing the push out bond strength using Universal Testing Machine. The mode of bond failure of material to root dentin was analyzed using microscope. Data was analyzed using ANOVA and post-hoc tukey’s test.
Results: After 24hrs, there was statistically non-significant difference but After 7 days, ProRoot MTA showed significantly higher bond strength as compared to other tested groups. While analyzing the mode of bond failure, ProRoot MTA had adhesive failure, Biodentine had cohesive failure and Portland cement had mixed type of bond failure.
Conclusion: All the tested materials showed comparable bond strength but ProRoot MTA had highest bond strength to root dentin among the other tested materials.
