The basement membrane of the enamel organ in human odontogenesis.

This study was designed to record findings of a basement membrane in human fetal jaws relative to the oral epithelium, dental lamina, and developing teeth. With the use of Lillie's allochrome stain, this could be followed from the oral epithelium and dental lamina to the tooth jaws. The basement membrane was easily traced along the inner enamel epithelium, but only after elimination of the counterstaining phases was it visible adjacent to the outer enamel epithelium.
