Abstract

Background
The Coronoid process is a thin bony triangular projection which arise from the ramus of the mandible. Two main muscles of mastication attached are temporalis and masseter. It varies in both shape and size. Its anterior border is convex and continuous with the anterior border  ramus of the mandible. The variations in the shapes of coronoid process are of mostly three types they are  triangular, hook, and rounded. Different morphological variations of the coronoid process have been documented in literature as indispensable aids in anthropological and forensic studies.
Materials and Methods: In the present study, a total of 84  human mandibles of unknown sex and age was taken from the department of anatomy and forensic medicine, for morphometrical analysis and evaluated. Shapes of the coronoid process on both sides of the mandible (168 sides) were analyzed. The various shapes of the coronoid process were observed and recorded.
Results:We observed that The triangular shaped coronoid process was most prevelant in 104(61.90%) sides, the hook shaped was reported in 40(23.80%) sides & the round shaped was found only in 24 (14.30%) sides. So, triangular shaped coronoid process was most prominent in our study followed by hook and round shaped was least. The bilateral occurrences of all the three types were more common. All values were compared with series of other workers to draw the conclusions.
Conclusion:
The knowledge of the morphological shapes of the coronoid process is useful for the oral and  maxillofacial surgeons. It makes an excellent donor graft site for reconstructive surgeries of the face like orbital floor repair, alveolar defects repair maxillary augmentation and repair of non-union fracture of mandible. In this regard, the present study was undertaken to depict various morphological disparities of the coronoid process in our ethnic group so as to aid in personal identification. It also helps in determining buccal vestibule during denture fabrication.
