The modification of dental mineral tissues during the life and mainly due to the apposition of dentin and cementum on the root surface have proved to be useful evidence to assess age of unknown body of adults. The study aims to experiment the correlation between the thickness of root cementum with the age of the subject. The study used 127 extracted teeth from people aged 16 to 90 years old. The aim of this research was to verify the reliability of the method using a single dental parameter based on the correlation of the radicular cementum thickness and the chronological age of the subject. The thickness was measured both on the lingual side and on the vestibular side of the tooth, at two different levels: apex and one third of the root length from the apex. The data were reported through a Cartesian graph with the X-axis showing the cementum thickness and the Y-axis showing the subject's age. The correlation between age and the increase of the cementum thickness is more statistically evident when the measurement is taken at the apex (R2=0.67), in comparison with the measurement taken at approximately one third of the root length from the apex (R2=0.56).The research supports the conclusion that the thickness of dental cementum increases progressively and quite regularly during the life, thus resulting an useful evidence that can contribute to the estimation of age of the subject.

Abstract
The modification of dental mineral tissues during the life and mainly due to the apposition of dentin and cementum on the root surface have proved to be useful evidence to assess age of unknown body of adults. The study aims to experiment the correlation between the thickness of root cementum with the age of the subject. The study used 127 extracted teeth from people aged 16 to 90 years old. The aim of this research was to verify the reliability of the method using a single dental parameter based on the correlation of the radicular cementum thickness and the chronological age of the subject. The thickness was measured both on the lingual side and on the vestibular side of the tooth, at two different levels: apex and one third of the root length from the apex. The data were reported through a Cartesian graph with the X-axis showing the cementum thickness and the Y-axis showing the subject's age. The correlation between age and the increase of the cementum thickness is more statistically evident when the measurement is taken at the apex (R2=0.67), in comparison with the measurement taken at approximately one third of the root length from the apex (R2=0.56).The research supports the conclusion that the thickness of dental cementum increases progressively and quite regularly during the life, thus resulting an useful evidence that can contribute to the estimation of age of the subject.File | Dimensione | Formato | |
