ABSTRACT

Aim: In this study we are evaluating the fracture resistance of roots filled with AH plus, metaceraseal, sealapex and MTA fillapex sealers. Materials and Methods: Forty teeth with single roots were chosen. Then these samples were randomly distributed among four groups. Group I (n=10): root canals obturated with F4 protaper point using AH plus. Group II (n=10): root canals obturated with F4 protaper point using sealapex. Group III (n=10): root canals obturated with F4 protaper point using MTA fillapex. Group IV (n=10): root canals obturated with F4 protaper point using metaceraseal. The coronal 1 mm of the obturation material was cut, and the roots were coronally sealed with temporary filling material. Fracture resistance was tested using a universal testing machine The maximum force applied to fracture each root was logged in Newton (N). Inferential statistics: One-way ANOVA test followed by Tukey’s post hoc analysis will be used to compare the fracture resistance of roots filled with AH plus, metaceraseal, sealapex and MTA fillapex sealers. The level of significance [P-Value] will be set at P<0.05. Results: The mean Fracture Resistance was significantly highest in MTA Fillapex & Metaceraseal group followed by Sealapex group and least in AH Plus group. Conclusion: It can be concluded that root canal sealers increased the fracture resistance of endodontically treated teeth, Highest fracture resistance within the sealer groups was shown by MTA Fillapex & Metaceraseal group followed by Sealapex group, and least in AH Plus group.
