Furcation
Pronunciation: fur-KAY-shun
The anatomical area where the roots of a multi-rooted tooth diverge from the main trunk of the root.
Full Definition
Furcation refers to the point at which the roots of a multi-rooted tooth separate. In clinical dental records and notes, furcation involvement is documented when periodontal disease has progressed to the point where the bone and soft tissue between the roots has been destroyed. Editors must ensure the term is not confused with 'bifurcation' (two roots) or 'trifurcation' (three roots), both of which are sub-types of furcation. Classification systems such as Glickman's grades (I–IV) are commonly referenced alongside this term. Accurate transcription of furcation grades in dental charting is critical for treatment continuity.
Usage
Usage note: Always lowercase unless beginning a sentence. When editing charts, verify that the grade or class system cited is applied consistently throughout the document.
