Teeth fragments from members of a famil?
clinically and genetically diagnosed as having
amelogenesis imperfecta were studied by scanning
electron microscopy and X-ray microprobe analysis to
establish the morphological patterns and the quantitative
concentration of calcium in the enamel of anterior
(canine, incisor) and posterior (premolar and molar)
teeth. The prism patterns in the enamel of teeth from
both regions were parallel or irregularly decussate, with
occasional filamentous prisms accompanied by small,
irregularly rounded formations. Prismless enamel
showed the R- and P-type patterns. Calcium levels in
enamel of amelogenesis imperfecta and control teeth
differed significantly between anterior and posterior
teeth, indicating that the factors that influence normal
mineralization in different regions of the dental arch are
not altered in the process of arnelogenesis imperfecta.
