EVALUATION OF INCIDENCE OF VARIOUS TYPES OF CORONOID PROCESS IN SOUTH INDIAN POPULATION

Abstract

Introduction: The mandible is the facial skeleton's largest and most strong bone. Coronoid process which is present
in the mandible gives attachment to temporalis muscle. Coronoid process varies in shape and size which is used for
forensic identification. The morphology of the coronoid process is due to hormonal and genetic changes. The Coronoid
process acts as a perfect donor for reconstruction of orbit. Orthopantomography is a radiographic method used to
visualize mandibles. It also provides a rotational view of the jaw. The aim of the study is to analyse the various shapes
of the coronoid process in the South Indian population using OPG.
Materials and methods: The study was conducted in a private dental college. This study was classified according
to gender-male and female. Different shapes of the coronoid process were analysed in the study A total of 80 sample
radiographs were included in the study. The collected data was tabulated and analysed statistically using chi square
test for its significance using SPSS version 2.3.
Results: There are different shapes of coronoid process in males and females. In our study round shaped coronoid
processes were found common in males and triangular shaped coronoid processes were found common in females.
Flattened shaped coronoid process on the right was found only in females.
Conclusion: From obtained results within the limitations of the study it can be concluded that round and triangular
shape is observed to be a common occurrence and there is no significant difference found between males and females
population. Future studies with live models and larger sample size should be conducted.
