ABSTRACT
A total of 100 extracted incisors, canines and premolars were collected forthis study. The gender and age of the patient, as well as the cause ofextraction, were recorded. Only sound teeth were included in the study. Teeth were stored in 4% buffered formaldehyde solution. Using long coneparalleling technique with XCP film holder to facilitate standardization, eachtooth was embedded in wax and placed parallel to the film and perpendicular tothe X-ray beam. Measurements on dental radiography [to the nearestmillimeter] were done using a stereoscope with a measuring eyepiece [graduatedlens] and included pulp and root lengths and widths. Results showed thatratios presenting the size of the pulp cavity were negatively correlated withage, confirming the inverse relationship. It was also shown that sex madesignificant contribution in the regression formula [when using all variablesand when using densitometric measurements done] resulting in strongercorrelation with age [r 0.74 - 0.91, p <0.01 and 0.0001]. Yet, if sex was notknown still estimates of age based on dentition are more likely to be correctthan those based on osseous development
