Sagittal and Vertical Occlusal Cephalometric Analyses of Pancherz among Malaysian Malays and Malaysian Chinese

Abstract

The aim of this study was to analyze sagittal and vertical occlusal cephalometric analyses of Pancherz among Malaysian Malay and Malaysian Chinese. Further comparisons of each area of interest are needed to know the differences between them. It was a cross sectional study and total 640 lateral cephalogram (Malay=407, Chinese=233) were randomly selected among orthodontic patients. All sagittal and vertical occlusal cephalometric parameters of Pancherz were measured digitally using Planmeca software. Descriptive statistics, gender and racial dimorphism were analyzed using IBM SPSS Statistics Version 22.0. Data were analyzed using independent t-test. Statistically significant disparities were found in the Malaysian Malay population between males and females for 3 of 10 in the vertical occlusal analysis but there were no significant disparities found in sagittal occlusal analysis. In the Malaysian Chinese population, significant disparities found between males and females for 1 of 11 in sagittal occlusal analysis and 6 of 10 vertical occlusal analysis. Statistically significant disparities were also found between Malaysian Malay and Malaysian Chinese population for 10 of 11 parameters in sagittal occlusal analysis and 5 of 10 parameters in vertical occlusal analysis. In conclusion, there were significant disparities between Malaysian Malay and Malaysian Chinese in general and also between genders of each race seen using cephalometric analyses of Pancherz.
