Morphological and anthropological aspects of human triangular deciduous lower first molar teeth.

abstract：:Specific, well-characterized antisera to the extracellular matrix glycoprotein tenascin were used. Immunoreactivity was detected in association with dentinal tubules; it was particularly prominent in the tooth crown, and was stronger within matrix than within predentine. In contrast, there was no anti-fibronectin stai...
