External resorption is much more common than internal resorption. It can affect any part of the outside of the tooth, from the roots to the cementum on the outside. On the outside of teeth,

Resorption initiation. The external surface of the root is surrounded by a protective layer called precementum. Damage to this layer allows resorptive cells (odontoclasts) to penetrate the root. The portal of entrance into the root can range in size from pinpoint to a much larger defect.

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.

Unknown: Internal surface resorption: Oval-shaped enlargement in the apical 1/3 of the root canal. Mild traumatic injury.

Table 1: Radiographic appearance of internal and external resorption, early pulpal death, and dental caries By this definition, internal resorption is “a defect of the internal aspect of the root following necrosis of odontoblasts as a result of chronic inflammation and bacterial invasion of the pulp tissue.”

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.

Är en utväxt från hårfollikelns ''external sheath''. Den sekreterar talg Här sker heller ingen resorption, till skillnad från den eccrina. Internal root sheath består även det av 3 lager: inifrån: Cuticle, huxley's layer, och Henley's layer. När håret 

2 It can also be caused by a sudden injury (trauma following reimplantation) or 2014-01-20 The pathology of internal root resorption (IRR) is caused by transformation of normal pulp tissue into granulomatous tissues with giant cells, which resorb dentin. (3) This, in turn, resorbs the dentinal walls, advancing from the center to the periphery. 2021-04-08 Root resorption occurs in three stages: initiation, resorption, and repair. 6,7 The process may have a self-limiting characteristic and may not be clinically detected.

In each case there was only one correct diagnosis and treatment option that had been previ-ously established by the consensus committee and in resorption cases confirmed after the completion of the treatment of the lesion.

External Root Resorption is similar to internal root resorption but the resorption occurs from the outside and goes inwards. 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.
