Fig. 2

Backscatter SEM images of sagittally cut incisors from AMBNHET (A, B) and AMBNΔ5–6 (C, D) mice from corresponding late secretory (A, C) and erupted (B, D) portions of the tooth. The absence of full-length AMBN (B) results in lack of formation of an enamel layer and its replacement by a thin, dysplastic mineralized layer along the dentin surface (arrow), and the presence of mineralized masses throughout the disorganized enamel organ (EO). (D) A shift of the gingival margin with respect to the tip of the incisor and the alveolar bone is also observed. CT, connective tissue.
