[Changes in the transparency of dentin: computerized densitometric analysis].

Computerized densitometry was utilized to carry out a quantitative and distributive study of dentin transparency in dental roots from different age individuals. By means of original software S.A.M. (Shape Analytical Morphometry) a densitometric reading of transilluminated whole dental root was performed and so obtained densitometric matrixes were worked for grey level classification and correspondent areas evaluation, false colour restitution, pseudotridimensional and row/column barr graphs, isodensity outlines and density inclination maps. Results are discussed for both age evaluation in forensic application and for altered dentin recognition in pathological conditions.
