Anatomical and Morphological Features of Root Canal in

Abstract

Background: Many teeth that are affected with irreversible pulpal lesions can remain with endodontic treatment and keep their function in dental system for years. The most important factor in endodontic therapy is related to chemical and mechanical preparation. Since the most unsuccessful endodontic therapy in mandibular incisor results from unclean root canal, especially the lingual canal, so we performed this study to determine the anatomical and morphological features of root canal in mandibular incisors.
