title: IgE in postsecretory ameloblasts suggesting a hypersensitivity reaction at tooth eruption.
abstract: The clinical symptoms associated with the eruption of primary teeth resemble a mild hypersensitivity reaction. Light microscopic examination showed that IgE accumulated in postsecretory ameloblasts. The formation of IgE was elicited by enamel matrix proteins, which are chemotactic for mast cells.
