[Post-eruptive formation of the root apex. A scanning electron microscopic study].
During the course of root formation, histologic examination show many pictures; however, the last stage of root formation is not well documented. In this paper, we describe cellular and extracellular components of immature teeth with incompletely formed roots. The odontoblast cells were observed with reticular fibers. The cementoblasts and epithelial cells covered the cementoid tissue. The results are discussed.
