The possible relationship between the mineralization of dentin and the composition of its organic matrix.
Using the rat incisor as a model, evidence is presented that enamel-related (ERD) and cementum-related (CRD) dentins exhibit differences in composition. Whereas the ERD is rich in highly phosphorylated phosphoproteins, the CRD is rich in lowly phosphorylated phosphoproteins. These differences are accompanied by and possibly related to differences in composition and physical properties of the mineral phase.
