Abstract :
The present study aims to investigate and compare the hard and soft tissue cephalometric
measurement among Malaysian Malay and Chinese subjects. This study is a cross-sectional study of
secondary data. Data consists of 470 standardized lateral cephalometric radiographs of Malaysian
Malay and Chinese adults which were picked randomly among orthodontic patients of Hospital USM.
The criteria of selection were pre-treatment lateral cephalometric film of Malay and Chinese orthodontic
patients aged 18-25 years which has good quality with visible landmarks. All cephalometric landmarks
were located and determined and subsequently all measurements were done per COGS analysis using
CASSOS software. Independent t-tests were performed for statistical comparison. Out of the 38
measurements, 4 were found significantly different between the sexes for Malaysian Chinese and 18
were found significantly different between the sexes for Malaysian Malay. Statistically significant
disparities were also found between Malaysian Malay and Chinese as 16 measurements has p-value
of < 0.05. Disparities were observed in COGS values between the two races and each sex group.
