For this reason, it is important to treat it as soon as it is detected. 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. Sometimes external resorption is not easy to diagnose from the radiograph when the canal outline is indistinct. Three types of external resorption are: External resorption associated with orthodontic forces is typically surface resorption and is most commonly found in the apical region of the roots causing them to become shorter. Repair with new External resorption may appear on the outer surface of the tooth in the form of deep chips or holes. Resorption that extends to the roots of the tooth can be visualized in an X-ray report as a flattening of the root tips as well as a reduction in their length. Root resorption can occur in a number of ways This type of external root resorption is often seen radiographically as an extensive peri-radicular radiolucency associated with an extensive inflammatory response to endodontic pathosis.

The tooth tissue is resorbed and … Inflammatory Root Resorption after Braces. There is one type of root resorption that is unfortunately a bit more uncommon. This kind occurs after aggressive tooth movement, and it seems to have a partially genetic basis. This panoramic x-ray is from a long-time patient in our practice. Tooth resorption, including root resorption, involves parts of the tooth being broken down by cells called osteoclasts. This process can occur internally, in the tooth pulp, or externally, affecting the enamel or cementum.

2 It can also be caused by a sudden injury (trauma following reimplantation) or persistence over time (orthodontic force). 3 The treatment varies according to the severity of the root 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 canal through the radiolucency of the external resorptive defect (Fig.

Root resorption can be detected only on X-rays. that the root of that second tooth will exhibit root resorption, specifically termed external root resorption.

As a result inappropriate treatment is often initiated. This paper provides three‐dimensional representations of cervical external resorption, based on X‐ray microfocus‐tomographical scanning of a case, which will aid the dental practitioner in recognizing characteristic features during clinical inspection. Physiologic apical resorption—External surface resorption, transient apical resorption, and transient root resorption are terms previously used to describe normal physiologic response of the root surface to physiologic stimuli of the masticatory system, such as chewing pressure and muscle forces on the teeth.

External Apical Resorption– This type of resorption occurs when the tooth roots begin As resorption can be easily diagnosed with X-rays and 3D imaging, we 4 Oct 2014 In this video Dr. Allen Ali Nasseh shares a case of external root resorption and his approach at a combined non-surgical / surgical repair of the Read about how we restored a damaged tooth with a dental implant. We'll explain the cause, show an example case and discuss treatment.

This process is poorly understood. External inflammatory root resorption is a process that starts from minor lesions of the periodontal ligament and/or cementum, due to trauma or contamination with bacteria that induce small root resorption cavities, reaching the dentinal tubules and the root canal. 1 Initially, it does not involve pulp tissue.

2 It can also be caused by a sudden injury (trauma following reimplantation) or persistence … X-ray examinations showed root resorption in the teeth involved in an odontogenic keratocyst.Root canal treatment with calcium hydroxide mixed with propylenglicol was performed. 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 canal through the radiolucency of the external resorptive defect (Fig. 1).

External resorption associated with orthodontics (braces) occurs at the tip of your tooth’s root, is typically minor in severity and self-limiting in the vast majority of cases. Cervical (up at the neck of your tooth’s root by the jawbone line) external resorption is treatable and can be resolved as long as it is caught early enough.
