Rare Root Canal Configuration in a Second Maxillary Molar: A Case Report

Endodontic treatment is a routine procedure performed daily in dental practices. It requires a good knowledge of all the variations in the configurations of the root canal systems of different groups of teeth. A thorough analysis of all available imaging studies is necessary. Difficulties may arise in the analysis and treatment protocol for rare morphological features of the root canal system. A representative of these cases is the single-rooted upper second molar with one wide canal. The purpose of this article is to present a case with an unusual upper second molar morphology: a single wide root canal. Magnification and good anatomical understanding facilitated detection and treatment, preserving the tooth's function within the dentition.
