Correlation coefficients between tooth crown and root measurements and among root measurements in an individual dentition were calculated in order to determine the difference in variability between tooth crown and root dimensions. Root lengths were highly correlated with each other not only within the upper or lower dentition, but also between the upper and lower dentition. Total heights of both upper and lower dentitions had significant correlation coefficients with almost all the crown heights, but not so many with buccolingual and mesiodistal diameters. These facts indicated a high variability of root length. However, high correlations within root lengths suggested their invariabilities within an individual dentition.
