Bell Stage of IDE at Cusp of Tooth
Up to mid bell stage, phenomenon within the dental organ have been concerned only with altering the shape or morphology of the developing tooth. The columnar cells of the IDE (B) will now induce the differentiation of columnar-shaped odontoblasts (F) from the dental papilla (A). This process begins at the tip (cusp) of the cap stage tooth germ where the oldest IDE cells are found. The youngest IDE cells lie in the periphery (not seen in this image) where they are arising from the proliferating epithelial at the cervical loop.
