 The dental lamina is a band of epithelial tissue seen in histologic sections of a developing tooth.The dental lamina is first evidence of tooth development and begins when humans at the sixth week in utero or three weeks after the rupture of the buccafuringeal membrane. It is formed when cells of the aural ectoderm proliferate faster than cells of other aureus. As described as an ingrowth of aural ectoderm, the dental lamina is frequently distinguished from the vestigular lamina, which develops concurrently. This dividing tissue is surrounded by an, some would argue, stimulated by epimysenchymal growth. When it is present, the dental lamina connects the developing tooth butt to the epithelium of the aural cavity. Eventually, the dental lamina disintegrates into small clusters of epithelium and is resorbed. In situations when the clusters are not resorbed, this remnant of the dental lamina is sometimes known as the glands of cereus. Eruption cysts are formed over the developing tooth and delay its eruption into the aural cavity. This invagination of ectodermal tissues is the progenitor to the later hemorrhobe blasts and enamel while the ectomysenchym-3 is responsible for the dental papilla and later o-dota blasts.
