Classification of Furcation Involvement - A Literature Review

Abstract

Inflammatory periodontal disease, if unabated, ultimately progresses to attachment loss sufficient to affect the bifurcation or trifurcation of multirooted teeth. In multi-rooted teeth, the bone destruction can reach the area of root separation, thus exposing it to microbial colonization. In this occurrence, a “furcation involvement” is created. This article reviews several classifications that have been proposed in an attempt to describe the anatomy of the furcation involvement which could be important for prognosis and diagnosis of the involved teeth and for the treatment planning. Keywords: Classification of furcation involvement, Inflammatory periodontal disease, Periodontitis
