Predominance Indistribution of Cementoenamel Junction in Permanent Maxillary Central Incisors - A Light Microscopic Study

Abstract

Background: The Cemento-enamel junction (CEJ) is the structural connection between enamel and cementum. CEJ is positioned around the gingival fibres of the healthy tooth that exhibits as an important point of reference in clinical dentistry.

Objective: The study aimed to describe the predominance in distribution of the cemento-enamel junction on different teeth surfaces mainly the labial and palatal surfaces of permanent maxillary incisors.

Methods: The study sample consists of 30 extracted maxillary central incisors. Longitudinal sections of each tooth were done by ground section method.The labial and palatal cemento-enamel junctions were examined under light microscopy.

Results:An overlapping interrelation between root enamel and cementum waspredominant.The frequency of gap junction was higher than previous studies and edge-edge relationship was the least.

Conclusion:The CEJ plays an utmost essential reference in clinical dentistry and exposure of which leads to many pathological changes. Hence the understanding of distribution of CEJ is very important.
