Microscopic histological findings of the lesion. (A and B) HES, magnification ×10. A tubular dentin-type mineralized tissue associated with focal enamel-like mineralized tissue is surrounded by a non-mineralized pulpal-type tissue coated with its odontogenic epithelium. Blue square labeled corresponds to the area shown in Figure 6 (D). (C) HES, magnification ×200. An eosinophilic tubular dentin-type mineralized tissue associated with a more basophilic enamel-like mineralized tissue. (D) HES, magnification ×200. An odontogenic epithelium is found focally. Some ghost cells and dystrophic calcifications are present.
