Background: Knowledge about the morphological shapes of the coronoid process is useful for the maxillofacial surgeon. The Coronoid process can be easily harvested as a donor bone. It is also helpful in determining buccal vestibule during denture fabrication.Aim of the study: To find out the variation in shape of coronoid process and the intercoronoid distance in dry mandible of Maharashtra region. Material and Methods:One hundred and fifty seven (male 84 and female 73) dry mandible of Maharashtra region were studied for variations of shape in coronoid process of both sides and the intercoronoid distance .Results: Triangular shape coronoid process was found in 204 (64.97%), Hook shape in 66 (21.02%) sides. and rounded in 44 (14.01%) sides of mandible. Mean intercoronoid distance among males was found to be 9.2000 and 9.100 in females. Conclusions:It was found that most common shape of coronoid process found in our study was triangular. Mandible with hook shape coronoid process was almost equal in male and female mandible while triangular shape was slightly more in the male .

Coronary artery disease (CAD) is going to become a significant cause of death in the world. The CAD is increasing day by day because of the changing lifestyle of people. The responsible factors for CAD are diabetes, hypertension, addiction and heredity also. So, the present work is undertaken to study the dominant pattern of coronary artery in the Maharashtra population. The present study was a hospital-based, prospective and observational study of 360 patients who have coronary artery disease undergoing coronary angiography.  This study carried out from May 2018-November 2019 of both genders of 25 years of age and above [Male-215(59.72%) and female was 145(40.27 %)]. Out of that, the youngest patient below 40 years male was 30(73.17%), and the female was 11(26. 82%). While above 40 years males were 185(57.99%) and females was 134(42%). The patients with a history of by-pass surgery and angioplasty were excluded. Invasive angiography was performed by either femoral or radial artery using radio-opaque dye (OMNIPCK-50ml) that is visible by an x-ray machine (GE. INNOVA). The socio-demographic Proforma of patients, the pattern of coronary arterial dominance were recorded. Right coronary artery was dominant in 273(75.83%) patients observed in this study. While LCx was dominant in 49(13.6%) and co-dominant in 38 (10.55%) patients. Knowledge of study can be helpful to cardiologists for anatomical assessment of coronary arteries for diagnostic purposes and invasive studies.
