Editor: Alan R. Gould. External cervical root resorption involving multiple maxillary teeth radiograph did not identify any lesions suggestive of a central vascular One year after the sectioning of the fused teeth, a well demarcated radiolucency in tooth 42 was observed by radiography, similar to IRR. CBCT scanning was 13 Jun 2016 This radiograph is exposed using exaggerated horizontal angulation of approximately 20° to 30° to the mesial or distal. If the radiolucent area 30 Jul 2020 Root resorption as evidenced on a dental x-ray; courtesy of Spear Education. As the name implies internal resorption begins inside the tooth. 17 Oct 2017 Radiographic examination showed a radiolucent area in the cervical region of tooth 21, thereby suggesting external cervical resorption. No Teeth that underwent pulp treatment presented with external resorption.
Introduction: The aim of this study was to compare the sensitivity and specificity of digital periapical radiography and cone-beam computed tomographic (CBCT) imaging in the detection of natural and simulated external root resorptions (ERRs) with micro-computed tomographic (micro-CT) imaging as the reference standard. Usually resorptive lesions are first seen on conventional intraoral radiographs. Due to inherent limitations of these two-dimensional images, it may be difficult to differentiate internal resorption and external cervical resorptive lesions. 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.” The true cephalometric lateral skull radiograph is one of the most accurate ways of determining the root length of the upper incisors, but detailed diagnosis of external root resorption is often University of Nebraska College of Dentistry Dental Class of 2021Faculty webpagehttps://www.unmc.edu/dentistry/faculty/kimsung.htmlCBCT interpretation reporti The Assessment and Management of External Cervical Resorption with Periapical Radiographs and Cone-beam Computed Tomography: A Clinical Study Kreena Patel BDS(Hons), MJDF, RCS(Eng) , Francesco Mannocci MD, DDS, PhD, FHEA and Shanon Patel BDS, MSc, MClinDent, MFDS, MRD, PhD Journal of Endodontics , 2016-10-01, Volume 42, Issue 10, Pages 1435-1440, Copyright © […] 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.
Vasconcelos et al 13 showed that the 2D nature of conventional radiographs limits the obtained information, since the quality of radiographic images is affected by the angle of the x-ray spectrum, leading to anatomical superimpositions during image preparation steps, which leads to difficulties in determining what disease process has occurred, and whether internal or external resorption, or 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.
27 Feb 2020 External resorption is comparatively easier to see than internal It is like deep holes or chips, and the roots of a tooth can be visible in X-rays.

This is why it is very important that you have all necessary x-rays taken at regular intervals. External resorption that can be cured requires treatment that entails
External resorption progressively gets worse over time. It initially shows up as a distinct dark spot on a routine x ray, but the resorption progresses very quickly. Radiographic features External cervical resorption typically presents as an asymmetrical radiolucency with irregular borders (Figure 4). The outline of the root canal is visible through the lesion indicating the resorption is on the external aspect of the tooth. 2021-04-08 · On radiographs: external has a moth-eaten appearance, internal has a balloon-like appearance Classical appearance of Internal is a pink tooth, External will only have this appearance if resorption occurs near the cervical region.

Radiographic examination showed external resorption and apical radiolucency at the actual tooth.

The diagnosis of resorption lesions usually occurs through incidental findings on routine radiographic examinations, especially in early cases where there is no symptomatology. 8 In contrast, the limitations of dental radiographic examinations are widely known3; periapical radiographs tend to underestimate the size of resorption lesions, while CBCT provides a more accurate estimate. 10,11

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. Secondly, the mesial-buccal-distal (MBD) rule may be employed whereby two radiographs are taken—one perpendicular to the root and the other at a mesial angle. 12 Internal resorption lesions will not shift no matter how severe an angle at which the radiograph is taken, whereas external cervical resorption will shift from its superimposed position over the root canal space and usually extend the radiograph, the accompanying bone resorption may be noticed.
