Fracture resistance of teeth obturated with Gutta percha and Resilon: An in vitro study.

Abstract

AIM:

The aim of this study was to evaluate and compare the fracture resistance of endodontically treated teeth filled with gutta percha and Resilon.

MATERIALS AND METHODS:

A total of 60 freshly extracted single rooted teeth are selected and their anatomical crown removed at the CEJ. All samples were instrumented with the Step-back technique. Samples were randomly divided into three groups of 20 samples each: Group A obturated by lateral condensation with gutta percha and AH plus sealer, Group B obturated by lateral condensation with Resilon; Group C recieved no filling. Restored teeth were subjected to compressive loading in a universal testing machine. The results of fracture resistance recorded and statistical analysis done.

RESULTS:

THE MEAN AND SD VALUES FOR THE GROUPS ARE AS FOLLOWS: Group A-536.555 ± 128.816, Group B- 885.943 ± 194.410 and Group C- 591.066 ± 68.97. It was seen that samples of Group B showed the highest fracture resistance followed by Group C. Group A showed the least fracture resistance.

CONCLUSION:

The results of this study showed that filling the canals with Resilon increased the in vitro resistance to fracture of endodontically treated single canal teeth when compared with gutta percha.
