Objectives: The objectives of this study were to assess if any systemic condition could be a potential predisposing factor for external cervical root resorption (ECRR), and to assess the long-term ECRR treatment outcome and its determinants. Methods: This study contains data from 76 patients (98 teeth) diagnosed with ECRR at the UBC Graduate Endodontics clinic, from 2008 to 2018. Data

PURPOSE: The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. MATERIALS AND METHODS: This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs.

Radiographic Findings. The periapical (PA) radiograph revealed a large irregular radiolucency on the distal (D) aspect of tooth #23 extending to the level of the crestal bone and into the root (Figure 25.1). Tooth #23 had Class 3 invasive cervical resorption. There was evidence of crest bone loss. No periapical radiolucency was noted for tooth #23.

Re-examine the radiograph to determine if the outline of the pulp chamber and/or root canal is visible. A shift shot can help determine if the chamber/canal outline is evident and not continuous with the radiolucent area. External Resorption External resorption originates in the PDL and is recognized by an irregular radiolucent area overlying the root canal; the canal outline remains visible and intact.

4. EXTERNAL CERVICAL RESORPTION • External cervical resorption is a localized resorptive lesion of the cervical area of the root below the epithelial attachment (thus it may not always be in the cervical region.) • In a vital tooth unless the lesion is extensive there is rarely pulpal involvement.

Internal Resorption Diagnosis. The following digital radiographs and were taken to help diagnose external root resorption. There were no probing depths greater than 3mm around the tooth, and the bone around the mesial of tooth #5 was obviously effected.

For more information and other Radiographic assessment of external cervical resorption. Periapical radiographs are essential to diagnose ECR. However, it is well established that they reveal limited information of the dentoalveolar anatomy because of their two‐dimensional nature, geometric distortion and anatomic noise (Bender & Seltzer 1961, Patel et al.

Unlabelled: Resorption of teeth is reviewed from a diagnostic perspective to clarify the confusion as to whether it is external or internal. The key features of the various types (external surface

It is usually asymptomatic and discovered by chance on routine radiographic examinations or by a classic clinical sign, “pink spot” in the crown. This paper emphasizes the etiology and pathophysiologic mechanisms involved in internal root resorption. Prognosis is Clinical and radiographic follow-up after 1 year showed an absence of symptomatology, repair of the periapical region, and paralysis of resorption. Introduction.

Table 1: Radiographic appearance of internal and external resorption, early pulpal death, and dental caries By this definition, internal resorption is “a defect of the internal aspect of the root following necrosis of odontoblasts as a result of chronic inflammation and bacterial invasion of the pulp tissue.”
