this determination is further complicated by the varying appearance of different histologic sections of the same developing tooth, which can appear to be different stages.
the tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth.
it is organized into three parts: the enamel organ, the dental papilla and the dental follicle.
the enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium.
these cells give rise to ameloblasts, which produce enamel and the reduced enamel epithelium.
the growth of cervical loop cells into the deeper tissues forms hertwig's epithelial root sheath, which determines a tooth's root shape.
