| Abstract | ||||
| Purpose: to evaluate fracture resistance following root canal instrumentation using different rotary nickel titanium (Ni-Ti) preparation systems (ProTaper Next, Spring Endo files with unheated finish (Spring Endo) and Spring Endo files with heated finish (Spring H)). Materials and methods: 30 recently extracted human permanent mandibular molars were collected for this study. Decoronation was done, then the mesial roots were separated from the distal ones. The mesial roots were randomly divided into 3 groups (n=10) according to the used instrumentation system; Group I: ProTaper Next system, Group II: Spring Endo system and Group III: Spring H system. (n=10). Roots were mounted in acrylic resin blocks and a vertical load were applied to them using the universal testing machine to apply fracture resistance test. Data were collected and statistically analysed. Results: ProTaper Next system showed less fracture resistance compared to Spring Endo and Spring H systems with statistical significant difference between them. Conclusion: Roots prepared with ProTaper next system are more liable to fracture compared to roots prepared with Spring Endo or Spring H files. | ||||
