Human Diseases Associated with Abnormal Tooth Roots

Journal of Oral Biosciences, 2009
Abstract Tooth development is a complicated process, characterized by reciprocal interactions between the dental epithelia and mesenchyme. During this process, inner and outer enamel epithelia form a doublelayered sheath, Hertwig's epithelial root sheath, after crown formation. A close association has been suggested between this root sheath (epithelia)
