A cemental tear is defined as an incomplete or complete separation within root surface along the cementodentinal tissue or along an incremental line (1-3).
Persistent endodontic lesion due to complex cementodentinal tears in a maxillary central incisor: a case report.
14 Benefits of combined methods are reduction in the number of radiographs required for working length determination, reduced procedure time, reduced radiation exposure to the patient, instead of determination of working length to the radiographic apex, apex locator are able to measure canal to apical constriction, cementodentinal
junction or apical foramen and radiographs are advantageous to inspect root anatomy and can be documented in patients record.
Para ello, el objetivo de la extension apical en la preparacion del conducto en endodoncia es alcanzar dicha union cementodentinal
At the apical foramen, the cementodentinal
junction (CDJ) or minor constriction is the landmark that anatomically and histologically determines where the pulp ends and the periodontal ligament begins.
8,9,10,11 In 1955, Kutler stated that the ideal place to end root canal treatment was the cementodentinal
