Unfolding Various Concepts of Junctional Epithelium

Abstract

The Gingival epithelium comprises of three different areas based on their anatomical and functional points of view 1) the oral or outer epithelium (OGE), 2) Sulcular epithelium (SE) and 3) Junctional epithelium (JE). The junctional epithelium may be regarded as the most interesting structure of the gingiva. The formation of junctional epithelium in the implant/mucosal interface can be considered as the first barrier of defense against oral micro flora. Any kind of disruption of this barrier will lead to initiation and progression of progression of periodontal disease. Hence, in this review we made an attempt to wrap various concepts of junctional epithelium formation, its role in disease progression and its relation to the implant surface.
