A second radiograph taken with a change in angle of the X-ray beam will result in a change in position of an external cervical root resorption lesion, whilst an internal resorptive lesion will not change position on parallax radiographs. Assessment of external root resorption using digital subtraction radiography. Digital subtraction radiography was investigated for its capability to detect and quantify experimentally produced external root resorptive defects in teeth.

Resorption affecting the roots of a tooth can be seen in X-rays as a shortening of the lengths of the roots and a The contributory factors implicated in external root resorption are periodontal infection, traumatic injury, orthodontic pressure, tooth bleaching and jaw cyst lesions [4, 15, 17]. 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.

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

Then the inner layer of your tooth, called dentin, is affected. Eventually the ligaments that help secure your tooth are affected. Root resorption is easily seen on an x-ray as a dark spot, but without an x-ray, it can be difficult to identify.
da Silveira HL, Silveira HE, Liedke GS, Lermen CA, Dos Santos RB, de Figueiredo JA. Diagnostic ability of computed tomography to evaluate external root
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).
