The matrix of organic fibres that calcifies to form dentin

At the growing end next to the apex of human developing teeth where dentinogenesis is most active, predentin exhibits its greatest thickness, whereas at the coronal region where primary dentin has been completely formed, predentin width is dramatically reduced to a mean value of 14.8 micron (Couve 1987 ).
