Furcation Involvement
The extension of periradicular or periodontal pathology into the furcation area of a multi-rooted tooth, relevant to both endodontic and periodontal diagnosis.
Full Definition
Furcation involvement describes the degree to which disease — whether of pulpal or periodontal origin — has affected the inter-radicular bone and tissues in multi-rooted teeth. In endodontic contexts, it is most commonly caused by accessory canals opening at the furcal floor or by furcation perforation during instrumentation. Clinically, it is classified using the Glickman or Hamp classification systems. Editors working on perioendo case reports should ensure that the aetiology (endodontic vs. periodontal vs. combined) is clearly stated, as this determines treatment planning and prognosis.
Usage
Usage note: Do not shorten to 'furcation' alone in formal clinical writing; the full phrase 'furcation involvement' should be retained on first use.
