title: The maxillary arch and its relationship to cephalometric landmarks of selected malay ethnic group.
abstract: The objectives of this study were to estimate the maxillary arch measurements, to assess the validity of Pont's & Korkhaus' Indices; to determine the relationship between maxillary arch form with head form; and to estimate the cephalic index (CI) of the study population. A cross-sectional study was conducted on 85 mature Malay students, 28 male students (32.98%), 57 females (67.02%) attending Teachers' Training College. Their mean age was 23.9 yr, and Cephalic Index (CI) 86.4 (95% Confidence Interval 85.5-87.3). Arch and head dimensions were significantly larger in males than in females. CI was not significantly different between males and females. Means of anterior arch width (AAW), posterior-arch-width (PAW) and arch-length (Lu) were 35.57mm, 47.3mm and 18.01mm respectively. They were significantly different from their corresponding Indices. Correlation Coefficient between bizygomatic width and anterior-arch-width was 0.18 and was not significant in both sexes of the present population.
