Scenаriо B An 18-yeаr-оld client hаs a healthy histоry with no significant findings. On examination of the dentition, findings reveal pitting of the enamel on the first molars, central incisors, laterals, and canines. In some areas these pits are stained. The client states that this pitting has always been present. The client has developed a carious lesion in a pit that appears at the incisal border of the cingulum of the right maxillary lateral incisor. An invagination of the enamel into the pulp cavity of this lateral incisor is noted. Enamel is derived from which of the following embryonic layers?
