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 ¡À 128.816, Group B- 885.943 ¡À 194.410 and Group C- 591.066 ¡À 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. %K Apexification %K artificial barrier %K calcium sulfate %K mineral trioxide aggregate %U http://www.jcd.org.in/article.asp?issn=0972-0707;year=2010;volume=13;issue=2;spage=61;epage=64;aulast=Baba
