Recovery after an endodontic treatment can only be assessed clinically, on the basis of symptomatological and radiographic data, for lack of histo-clinical correlations. An anatomicopathological examination of damaged tissues pinpoints the anatomical obstacles and tissular modifications apt to undermine the success of root canal work. The aim of endodontic treatment is to maintain or reinstate an environment conducive to healing through the use of a non-traumatic endodontic technique, followed by functional rehabilitation of the dental organ in its periodontia structures.
