Dentinogenesis Imperfecta, also known as hereditary opalescent dentin, is related to dentinogenesis imperfecta 1 and osteogenesis imperfecta, type vii. An important gene associated with Dentinogenesis Imperfecta is DSPP (Dentin Sialophosphoprotein), and among its related pathways/superpathways are Phospholipase-C Pathway and PI3K-Akt signaling pathway. Affiliated tissues include Tooth, bone and skin, and related phenotypes are pulp obliteration and abnormal dental root morphology
