This article explores the importance of root canal anatomy in endodontic procedures, and the recent advancements in three-dimensional computed tomography that have allowed for more detailed evaluations of root canal morphology. Research has uncovered that the root canal is a complex system, consisting of not only the main root canal but also lateral components, posing significant challenges in the treatment process.
A fundamental aspect of the Endodontic field is the knowledge of root canal anatomy. Using a variety of techniques, the internal and external anatomy of teeth have been extensively investigated throughout the past century. Recent improvements in three-dimensional computed tomography have enabled more detailed evaluations of root canal morphology in both clinical and laboratory settings. Essentially, researches have unveiled that the root canal constitutes a complex system, comprising not only the main root canal but also lateral components, including isthmuses, fins, accessory canals and apical ramifications. Undoubtedly, this intricate morphology poses a significant challenge when it comes to the process of shaping, cleaning and disinfecting the root canal system. This article aims to explore the anatomical aspects of the root canal system that impact the chemomechanical procedures.
