Significance of Apical Third. Anatomical Considerations of root apex

      Аннотация: The root apex is of interest to endodontists because the stages of root development and the type of tissue present within the roots of teeth are significant to the practice of endodontics. For successful endodontic treatment, knowledge of the internal and external root canal anatomy is critical. Unfortunately, two-dimensional radiographic images do not reveal all anatomic characteristics Also, appreciable knowledge of the morphology of the root apex and its variance, ability to interpret it correctly in radiographs, and to feet it through tactile sensation during instrumentation are essential for an effective rendering of the treatment of root canals.The importance of a thorough cleaning and fluid tightseal of the apical part of the canal for successful healing of the periapex was highlighted analogically as early as 1939 itself, by Kronfeld Achievement of a perfect seal at the apex using an inert filling material is conducive to an environment for proper healing at the periapex.
