Human tooth development the cells of the IEE secrete an organic matrix against the dentin. This matrix immediately mineralizes and becomes the initial layer of the tooth's enamel. Outside the dentin are the newly formed ameloblasts in response to the formation of dentin, which are cells that continue the process of enamel formation; therefore, enamel formation moves outwards, adding new material to the outer surface of the developing tooth. Enamel formation is called amelogenesis and occurs in the crown stage (advanced bell stage) of tooth development. "Reciprocal induction" governs the relationship between the formation of dentin and enamel; dentin formation must always occur
The Outermost House Endicott Peabody declared. It was also revealed during this ceremony that the National Park Service (part of the U.S. Department of the Interior) referred to "The Outermost House" on several occasions in its reports that were filed when making its evaluation of the Outer Cape land for National Park status in the 1950s.
