Comparative Evaluation of Fracture Resistance of Tooth after Lateral and Vertical Obturation Filled with Gutta-Percha and Resilon Obturating Material: An In Vitro Study

Introduction: Since long the obturating material and techniques have been discussed. The prime target of the material has always been to provide a three-dimensional obturation providing a monoblock concept thus strengthening the tooth. Aim: The aim of the study was to evaluate the fracture toughness of the root canal treated teeth after being oturated with Gutta-Percha and Resilon by lateral and vertical compaction techniques. Materials and Methods: A total of 75 human mandibular premolar teeth were taken and endodontically treated. All the teeth were divided into five groups with 15 samples in each. Access opening of all the teeth was done, and the cleaning and shaping were done up to 40 number file size. The samples were obturated with two materials which are Gutta-Percha and Resilon. All the teeth were subjected to compressive loading till the fracture occurred, and the readings were taken and compared. It was found that the teeth obturated with Resilon showed higher fracture resistance and that the obturating technique had no effect on fracture resistance. Result: This study shows the relevant difference between the two groups and that the group with Resilon showed better fracture toughness when applied with universal testing machine. Conclusion: This study concluded that Resilon is a better obturating material and that vertical condensation is better than lateral condensation.
