Welcome to EndoCast, a podcast series hosted by Ahmed Shawky and Francesca Cerutti. In this episode, we delve into a significant challenge in endodontics: file breakage. With insights from experts and comprehensive literature research, we aim to provide an in-depth understanding of this issue.
The Reliability of Scientific Research: Ahmed Shawky, a lecturer and avid reader of scientific articles, emphasizes the importance of the pyramid of evidence in determining the reliability of research. Meta-analysis and systematic reviews, being peer-reviewed, offer more credible information than individual case reports.
Incidence and Causes of File Breakage: Recent reviews indicate that file breakage occurs in about 5% of cases. However, the frequency increases among general practitioners and endodontists due to the complexity of cases they handle. Mandibular molars, known for their difficult access and complex anatomy, are most susceptible to file breakage, particularly in the apical third of the root canal.
File Types and Separation Risks: Various types of files, including Lentulo spirals, K-files, H-Files, R-files, and rotary files, are used in endodontic treatments. The episode discusses the impact of file design, size, and shape on its resistance to cyclic fatigue. For instance, larger taper instruments are more prone to fatigue than smaller ones.
Temperature and Kinematics: Temperature plays a crucial role in the durability of files. Higher temperatures reduce resistance to cyclic fatigue. Furthermore, the kinematics of file movement, such as continuous rotation versus reciprocating motion, significantly influences the likelihood of file fracture.
Conclusion: While this episode of EndoCast provides a comprehensive overview of file breakage in endodontics, it's just the beginning. Future episodes promise to explore strategies to prevent file separation and best practices for when it occurs. Listeners are encouraged to engage with the hosts by sharing questions and comments for upcoming episodes.
