Abstract
The purpose of this study was to examine the relationship between tooth root colour and age, and its possible application
in age assessment. In this research altogether 100 tooth roots have been analysed. All teeth, that is their roots, were
digitally recorded and the colorimetric treatment was made using Adobe Photoshop 7.0 computer program. Studies have
shown no significant difference between RGB values analysed on the whole root surface or only on its central part, with
certainty p>0.99. It is also established that there is no statistically significant difference in colouration on four anatomical
surfaces (buccal, mesial, lingual, distal) of tooth roots with certainty p>0.99 for red, p>0.99 for green and p>0.50 for
blue colouration component. Statistical data interpretation showed that there is a linear correlation between obtained
RGB values and age, with r=–0.994, p>0.99 for red component, r=–0.972, p>0.99 for green and r=–0.982, p>0.95 for
blue colouration component. From the obtained results it is possible to conclude that analysing the above mentioned parameter
we can easily establish dental age and this technique can be the basis of practical application in establishing
chronological age of man.
