Abstract : A total of 100 extracted incisors; canines and premolars were collected for this study from the Outpatient Clinic, Faculty of Dentistry, University of Alexandria. The gender and age of the patient, as well as the cause of extraction were recorded. Only sound teeth were included in the study. Teeth were stored in 4% buffered formaldehyde solution. Using long cone paralleling technique with XCP film holder to facilitate standardization , each tooth was embedded in wax and placed parallel to the film and perpendicular to the X-ray heam. To study the optical density of root dentine by densitometer, a reference graded aluminum wedge was used as a reliable scale. Measurements on dental radiographs (to the nearest millimeter) were done using a stereoscope with a measuring eyepiece (gtaduated lens) and included pulp and root lengths I and widths. Densitometer device type 102 was used for analyzing X-ray films. Results showed that ratios presenting the size of the pulp cavity were negatively 'correlated with age, confirming the inverse relationship between these two variables. It was also shown that sex made significant contribution in the regression formula (when using all variables and when (Ising densitometric measurements alone) resulting in stronger correlation with age (r from 0.74 to 0.91, p
