X-ray examination also helps in determining the external resorption. Usually defects have uneven edges, can penetrate the depth of the dentin, are detected on any root surface. But there are situations when the focus of enlightenment has clear boundaries, as with internal resorption.

XRT is a non-destructive diffraction method used to map lattice defects and strain in single crystals on the millimeter to micrometer scale. Applications Map 

TIP: External resorption over the facial or lingual surface of a root can be difficult to determine from internal resorption. Re-examine the radiograph to determine if the outline of the pulp chamber and/or root canal is visible. A shift shot can help determine if the chamber/canal outline is evident and not continuous with the radiolucent area. Some degree of external root resorption is a frequent, unpredictable, and unavoidable consequence of orthodontic tooth movement mediated by odontoclasts/cementoclasts originating from circulating precursor cells in the periodontal ligament.

However  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). Common location of external resorption – Most common in: 1) Upper front teeth: canines and incisors. 2) Lower first molars. External resorption progressively gets worse over time.

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.

16 Dec 2016 Your body begins to absorb the outer layer of your tooth's root, called Root resorption is easily seen on an x-ray as a dark spot, but without an 

a central incisor with massive external resorption of cervical crown and root structure that had to be extracted.

SUMMARY The causative factors of most root resorptions remain obscure, with many unanswered questions awaiting in-depth clinical and basic research work.

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.

What external root resorption treatments work? The best external resorption treatments are those that take place in the earliest stages of the condition. In this case, an ounce of prevention really is worth a pound of cure.

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 root resorption may be further subclassified into surface resorption, external inflammatory resorption, external cervical resorption, external replacement resorption and transient apical resorption (Patel & Pitt Ford 2007 , Patel & Saberi 2018 ). As a result, it is generally possible to trace the outline of the intact root canal walls through the external cervical root resorption lesion on a radiograph.

Root resorption is a disease process in which the root of a tooth is gradually being Your periodontist will assess this and determine whether treatment of the The white arrows on the x-ray scans show the position of the resorption

Root resorption may be simply classified by its location on the root surface as external or internal resorption. External root resorption may be further subclassified into surface resorption, external inflammatory resorption, external cervical resorption, external replacement resorption and transient apical resorption (Patel & Pitt Ford 2007 , Patel & Saberi 2018 ). As a result, it is generally possible to trace the outline of the intact root canal walls through the external cervical root resorption lesion on a radiograph. 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.

systems based on dental image analysis have the potential to become powerful tools to expand the scope of the panoramic x-ray exam and make it a relevant screening method for osteoporosis and carotid artery calcification. Oct 3rd, 2017. Root resorption may be simply classified by its location on the root surface as external or internal resorption.
