Abstract excerpt
BACKGROUND: Dentin sialophosphoprotein (DSPP) is an extracellular matrix protein, which is highly expressed in odontoblasts and transiently expressed in presecretory ameloblasts. DSPP mutations were related to dentinogenesis imperfecta (DGI), some of which can be accompanied by amelogenesis imperfecta (AI). However, the mechanism underlying DGI and AI caused by DSPP mutations is still unclarified. This study...
