Klinisk prövning på Root Resorption: Orthodontic intrusion

Figure 3A demonstrates that the coronal extent of the resorption is distal to the root canal. Figure 3A Radiograph of a maxillary central in-cisor with an extracanal invasive resorption In order to distinguish this from external resorption that may be on the facial or lingual surface of the root, an additional, angulated radiograph (shift-shot X-ray) can be helpful. This radiograph is exposed using exaggerated horizontal angulation of approximately 20° to 30° to the mesial or distal. Figure 2: (a) Radiograph after orthodontic treatment showing external root resorption and periapical radiolucency around tooth 11. (b) X-Ray fi ndings at 3 months follow-up with calcium hydroxide in tooth 11. (c) X-Ray fi ndings at 6 months follow-up with calcium hydroxide in tooth 11. 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.

External resorption radiograph

Sometimes external resorption is not easy to diagnose from the radiograph when the canal outline is indistinct. Three types of external resorption are: 2011-07-22 · Frequently external resorption is idiopathic; however it can also occur due to an inflammatory process, neoplasm or adjacent teeth. This case is external resorption due to an impacted third molar, which had been extracted shortly prior to this radiograph. Note the portion of root missing on the distal root. 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.

Three-dimensional cone-beam computed tomography radiography displays statistically significant root volume loss associated with maxillary expansion therapy. 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).

External resorption originates in the PDL and forms an irregular radiolucent area overlying the root canal; the canal outline remains visible and intact. Sometimes external resorption is not easy to diagnose from the radiograph when the canal outline is indistinct. Furthermore, the use of varying X-ray angles has been suggested to distinguish internal resorption from external resorption and to locate the site of entry (Seward 1963).

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. 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.

External resorption that can be cured requires treatment that entails We compared pano- ramic radiography (OPT) with cone-beam computed tomography (CBCT) in evaluating orthodontically induced apical root resorption. resorption is important in orthodontic treatment and treatment planning. The diagnosis of root resorptions mainly depends on radiographic examinations. Root resorption is a very important finding in the radiographic diagnosis of the oral and maxillofacial region. However, there are few reports about root r. Editor: Alan R. Gould.
