[Situation and extension of epithelial excrescences alongside the lip furrow band and the dental lamina].
3-D-reconstructions of serial sections of human embryos show that the margin of the lip furrow band is irregular and consists of an abundance of individual epithelial excrescences. Additional foldings of the lip furrow band extending over a length of up to 160 microns were found. The hypothesis that epithelial foldings in this region may be early anlagen of a perlacteal dentition is discussed and rejected.
