A Cephalometric Skeletal and Dental Analysis of Children with Excellent Occlusions

Abstract

A sample of twenty-five children with excellent occlusions between the ages of eight through eleven was collected. Cephalometric radiographs were taken of these children with the objective of obtaining normal standards for the purpose of compiling a cephalometric analysis especially applicable for diagnosis of malocclusions of the mixed dentition. A statistical analysis were performed on the data to calculate the means, ranges, standard deviations, and standard errors of the mean for each measurement. By the use of “t” tests, males were found to be significantly larger than females with respect to several linear measurements. However, there were no significant differences between males and females fore any of the angular measurements. No significant differences were found between this sample and Reidel’s sample; but, when compared to Downs’ sample, the upper and lower incisors of this sample were found to be significantly more protrusive. A correlation study of several pairs of measurements was also done. Significant positive correlations were found between the length of anterior cranial base and the length of the palate; and also between the lower facial height and the lower dental height. A significant negative correlation was found between the chin prominence and the angle of convexity.
