What is the process of internal resorption and what is the necessary treatment?
Internal resorption begins on the internal dentin surface and spreads laterally. It may or may not reach the external tooth surface.
The process is often asymptomatic and becomes identifiable only after it has progressed enough to be seen radiographically. The cause is unknown. Trauma is often but not always implicated. Resorption that occurs in inflamed pulps is characterized histologically by dentinoclasts, which are specialized, multinucleated giant cells similar to osteoclasts.
Treatment is prompt endodontic therapy. However, once external perforation has caused a periodontal defect, the tooth is often lost.
