Abstract:
Introduction. Endodontic treatment represents one of the most frequent and complex procedures in modern
dentistry. Its fundamental objective is the preservation of teeth affected by pulpal or periapical pathology
through removal of altered pulp tissue, disinfection, and hermetic sealing of the root canal system. However,
the anatomical complexity of the endodontic system, the diversity of available instruments, and individual
patient variables predispose this treatment to various errors, with direct consequences for prognosis. Root
canal anatomy is extremely variable: lateral canals, apical deltas, intercanalicular isthmuses, and unpredictable
root morphologies make each tooth a unique case [1,6,7].
