The lingual (root analogue) and the labial (crown analogue) mouse incisor dentin promotes ameloblast differentiation.
Previous studies have suggested that mouse molar ameloblast differentiation was triggered by the predentin-dentin. Knowing that enamel is absent on the lingual surface of the mouse incisor, the aim of this study was to compare in heterotopic tissue recombinations the behavior of mouse molar inner dental epithelium associated with lingual or labial mouse incisor dentin. It was shown that root-analogue and crown-analogue incisor dentin promotes ameloblast differentiation of competent molar inner dental epithelium.
