Beyond the Surface: Exploring Microcracks With Gen Endo File System Vs. Hyflex Edm in Root Canal Preparation

Type: article
Abstract: Aim: This study aimed to assess and compare microcracks formed during root canal preparation using two rotary file systems in mandibular molars.Materials and Methods: 202 extracted human permanent mandibular teeth meeting inclusion criteria were collected.Teeth were decoronated, disinfected, and sectioned to prepare samples for root canal preparation.Two groups, each comprising 101 specimens, were prepared using HyFlex EDM and Gen Endo rotary files.Microcracks were examined at 3, 6, and 9mm from the apex using scanning electron microscopy (SEM).Results: Microcracks were observed in both rotary file systems.Statistical analysis revealed a significant difference between the two groups (P=0.049).HyFlex EDM exhibited fewer microcracks compared to Gen Endo at all levels examined.Conclusion: Rotary endodontic preparation methods can induce dentinal defects, as evidenced by the presence of microcracks.HyFlex EDM demonstrated superior performance in minimizing microcracks compared to Gen Endo.These findings underscore the importance of careful selection of rotary instruments to mitigate the risk of iatrogenic damage during root canal preparation.
