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). Because the pulp in the root canal is not involved in cervical external resorption, it is usually possible to clearly distinguish the radiopaque mineralized outline of the

2017 Mar;87(2):328-337. doi: 10.2319/061916-481.1. 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.

A posteriori registration and subtraction of periapical radiographs for the evaluation of external apical root resorption after orthodontic treatment Eliane Maria Kreich , 1 Ana Cláudia Chibinski , 2 Ulisses Coelho , 3 Letícia Stadler Wambier , 2 Rosário de Arruda Moura Zedebski , 1 Mari Eli Leonelli de Moraes , 4 and Luiz Cesar de Moraes 4 Resorption is a condition associated with either a physiologic or a pathologic process resulting in a loss of dentin, cementum, and/or bone . Root resorption may occur after various injuries, including mechanical, chemical, or thermal injury. Generally, it can be classified as internal or external root resorption. External Root Resorption was shown on Radiographic Examination Figure 3. Postoperative Radiograph One Year After Root Canal Treat-ment With Ca(OH) 2 Paste Figure 4.

The early stage is asymptomatic and might be diagnosed by a routine radiograph or a clinical examination. Radicular resorption appears because of cementoclastic, dentinoclastic or/and osteoclastic activity. There are several types of external root resorption; the most common is the external inflammatory root resorption.

Introduction. 28 Apr 2017 The outline of original root canal is not distorted and can be differentiated from external root resorption by changing radiographic angualtions.

Moreover, few studies have investigated the effect of rice soup along with ORS in the treatment of this disease. This study aimed to explore effects of simultaneous 

This case is external resorption due to an impacted third molar, which had been extracted shortly prior to this radiograph.

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).

It is also indicative of an infection superimposed on a traumatic injury commonly seen in both avulsion and luxation injuries.
