Microscopic Analysis of The Variations of The Cemento-Enamel Junction in Himachali Population

Abstract

Cemento-Enamel junction is an anatomical point where the enamel of the crown surface connects to the cementum of the root. It lies in a region covered with the gingivalsoft tissue, but with the increasing age and due to many pathological conditions this junction may be exposed to the external environment and sometimes may provide a path for bacterial infection into the tooth. Aim: To analyze different types of Cemento-Enamel Junctions in thepopulation of Himachal Pradesh. Methodology: 40 extracted teeth were obtained from various regions of Himachal Pradesh. Ground sections of the tooth were made and analyzed for the type of Cemento-Enamel Junction under a Binocular Microscope. Result: Sharp junction was most frequent type of inter-relation between the two hard tissues in our study followed by Gap junction and Overlap type junction. Though we found cementum overlapping enamel in few cases but we could notfind any sample in which enamel was overlapped by cementum. Conclusion: Cemento-Enamel Junction presents different morphological patterns so a study of this region is necessary to avoid complications during various dental procedures such as sensitivity after bleaching or cervical caries after placement of crown or clamps.
