Internal external root resorption

The size and location of the lesions are limiting factors for the treatment and maintenance of the affected tooth. They can be classified as internal, when root canal is involved and external, when periodontal ligament is involved. External root resorptions are processes in which the loss of cementoblasts occurs causing the mineralized surfaces to be susceptible to the action of clastic cells. (2) There are two different kinds of resorption — external and internal. External resorption is resorption initiated in the periodontium and initially affecting the external surfaces of a tooth — may be further classified as surface, inflammatory, or replacement, or by location as cervical, lateral, or apical; may or may not invade the dental pulp space. The outline of original root canal is not distorted and can be differentiated from external root resorption by changing radiographic angualtions. 3 Sometimes pinkish spot on crown can be seen.

An internal resorption pink spot was historically referred to as the “pink tooth of Mummery,” named for the anatomist who described the condition.

Dens invagination: A review of literature and report of two cases

Root resorption in permanent teeth is pathological whether it is external or/and internal. Root resorption is induced by the clastic action of cells present in teeth and adjacent tissues (odontoclasts, dentinoclasts, cementoclasts and osteoclasts), being characterized by loss of dentin, cementum and/or bone [2] . 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 defect.http With external resorption, one can Figure 3: An example of external cervical resorption. Note the ability to trace the canal through the radiolucent defect.

External inflammatory root resorptions are pathologies that are difficult to treat. The treatment aims to eliminate the cause or stimulating factors of clastic cells such as infection and/or pressure. The size and location of the lesions are limiting factors for the treatment and maintenance of the affected tooth. They can be classified as internal, when root canal is involved and external, when periodontal ligament is involved.

2018-01-17 · Unlike external resorption, this process is arrested once the pulpectomy is done or remaining pulp becomes completely non-vital. In a study conducted by Thoma et al.,13 the authors reported internal root resorption in only one tooth out of the 1000 teeth studied It has been shown that like the cells of the periodontal ligament which are responsible for external root resorption, the pulp External resorption is much more common than internal resorption, but is often misdiagnosed. Treatment for internal resorption includes root canal therapy, followed by a definitive restoration. Although root canal treatment will halt the resorptive process, if the defect is too large, the tooth may mechanically fracture and fail. External cervical root resorption begins at the root surface as result of odontoclastic activity in the cervical area and is progressive in character. The pulp is only affected at a later stage of the process. The aetiology and pathogenesis of external cervical root resorption is not fully understood.

Similar causes have been related to external root resorption but no theoretically proven cause has been determined. In both cases of external root resorption or internal root resorption the condition cannot be ignored. In most cases diagnosis is simple but occasionally it may be difficult to differentiate between internal and external resorption. In internal resorption the outline of the canal is interrupted and usually appears as a smooth bulge. Internal resorption is often difficult to detect in posterior teeth and may be seen only after root treatment Internal and external root resorption: aetiology, diagnosis and treatment options.

However invasive cervical root resorption (ICR) which is a form of external root resorption can Root resorption is a clinical condition whereby the mineralized tissues of the root are appreciating the true nature, and managing the internal and external root 4, Alsufyani, 2013, CBCT assessment of upper airway changes and treatment Reliability of kinesiography vs magnetic resonance in internal derangement of of external root resorption associated with jackscrew-based maxillary expansion The diagnostic dilemma is further complicated by the need to differentiate between internal from external resorption.
