摘要：The exterior surface of the enamel layer of the teeth has frequently beensubject of morphological, morphogenetic and anthropological considerations. But regarding the interior surface of the enamel cap (enamel-dentin border), a few studies have been reported. To ascertain the morphological relationships between enamel surface and enamel-dentin border of the maxillary median incisor, the enamel has been artificially removed by means of acids.
