Osteoclasts recruitment in internal root resorption associated with external granuloma

Abstract

The internal root resorption can be associated with external granuloma. If there is a connection between the two pathological process through a lateral accessory canal is possible that some cells to be recruited from external granuloma. The possible mechanisms involved in osteoclasts recruitment from external granuloma and various dentin resorption patterns in internal root resorption will be discussed based on a case in which the upper lateral incisor with a history of pulp necrosis treated endodontically, developed an internal root resorption in association with external granuloma. Also, a review of literature was performed.
