Дефекты зубов

Defects in tooth form may indicate a development or endocrine disorder. In congenital syphilis, the incisors are constricted at the incisal third, producing a pegged or screwdriver shape, with a notch in the center of the incisal edge (Hutchinson’s incisors); the first molar is dwarfed, with a small occlusal surface and roughened, lobulated, often hypoplastic enamel (mulberry molar). In congenital ectodermal dysplasia, teeth are absent or conical so that from childhood, partial dentures are needed.
