The roles of epithelium in the development, structure and function of the tissues of tooth support are reviewed. Epithelium is involved in initiating odontogenesis which includes the tissues of tooth support and this role is discussed. Particular attention is paid to Hertwig's epithelial root sheath and its participation in the formation of the hyaline layer on the root surface as well as its possible role in initiating the differentiation of cementoblasts. The possible functions of the epithelial cell rests are reviewed and it is concluded that as yet no function can be ascribed to them. Evidence for an increasing role for dental epithelium in tooth eruption is presented and the role of dental epithelium in establishing the dentogingival junction is discussed, with the conclusion drawn that this role temporary.
本文综述了上皮组织在牙齿支持组织的发育、结构和功能中的作用。上皮组织参与启动牙发生，其中包括牙齿支持组织，本文将讨论这一作用。特别关注赫特维希上皮根鞘及其在牙根表面透明层形成中的作用，以及其在启动成牙骨质细胞分化中可能发挥的作用。本文还综述了上皮细胞剩余的可能功能，得出的结论是，目前尚未明确其功能。文中提供了关于牙上皮在牙齿萌出中作用日益增加的证据，并讨论了牙上皮在建立牙-龈结合中的作用，得出的结论是，这一作用是暂时的。
