Root Canal Morphology of Permanent Dentition

The importance of locating all existing canals within the RCS to achieve optimal prognosis has been discussed by many authors and potential negative effects of untreated canals on the treatment result have been debated with overwhelming evidence of missed canals in failed cases requiring endodontic retreatment.Conventional intraoral radiography provides clinicians with an accessible cost effective high-resolution imaging modality that continues to be of value in endodontic therapy. There are however specific situations both pre- and postoperatively where the understanding of spatial relationships afforded by CBCT facilitates diagnosis and influences treatment.The usefulness of CBCT imaging can no longer be disputed—CBCT is a useful task specific imaging modality and an important technology in comprehensive endodontic evaluation.The quality of evidence demonstrated that CBCT provided better detection of periapical lesions after endodontic treatment followed by periapical and panoramic radiography. The success of CBCT depends on the familiarity of the practitioner with the technique and the assessment of the images.
