Hindrance of tooth eruption and orthodontic tooth movement by focal idiopathic osteosclerosis in the mandible

摘要

The etiology of 10 is unknown. The IO lesion can be diagnosed clinically by viewing the radiographs. The dif- ferential diagnosis of 10 lesion should include condensing osteitis. The IO lesion is located at either the periapical or interradicular region and usually requires no treatment. It is often related to vital adjacent teeth. However, the condensing osteitis is frequently situated at the periapical region of a non-vital tooth or a tooth with chronic pulpitis. ' When the IO lesion is excised, it can be easily confirmed by histological examination of hematoxylin and eosin-stained tissue sections without the need of immunohistochemical staining to identify the tumor or cell origin.
