Retreatment of the maxillary lateral incisor with two root canals

Anatomy, Diagnosí, oral, Incisor, MicroscopyAbstract
In order to provide endodontic treatment, it is imperative to know the internal anatomy of the tooth, since it is not exactly like the external anatomy. The literature shows that most of the maxillary lateral incisors are single-rooted and have just one root canal. However, in rare cases, there may be more than one root canal. Today, the dental operating microscope is used in many stages of an endodontic treatment to facilitate the resolution of unusual cases, such as these with anatomical variations. The aim of this study was to describe the endodontic
retreatment of a left maxillary lateral incisor, in which a root canal left without appropriate treatment caused the first treatment to fail. This problem was solved with the magnification and lighting provided by the microscope, allowing complete sanitation of the root canals. In conclusion, in addition to allowing a better knowledge and study of the internal anatomy of the tooth, the dental operating microscope can help in the treatment of teeth with varied anatomies, ensuring a better prognosis for the endodontic treatment.
