A cementoblast is a biological cell that forms from the follicular cells around the root of a tooth, and whose biological function is cementogenesis, which is the creation of cementum (the hard tissue that covers the root of the tooth).Cementoblasts lay down the organic matrix of cementum which later gets mineralised by minerals from oral fluids. Thus the cementoblasts lay down collagen and secrete osteocalcin and sialoprotein. They possess all the organelles associated with protein synthesis su… (More on Cementoblast)
