the regulatory processes associated with tooth formation are being investigated by the identification of when , where , and how cell adhesion molecules ( cams ) , substrate adhesion molecules ( sams ) , dentin phosphoprotein , enamel gene products , and intermediate cementum products are expressed during sequential developmental stages of morphogenesis , cytodifferentiation , dentin , enamel and cementum extracellular matrix ( ecm ) formation , and biomineralization .
