Taurodontism and enamel hypomaturation associated with X‐linked abnormalities

Abstract

The association of taurodontism with hypoplastic/hypomature enamel defects is presented in two cases of X-chromosome aneuploidy (47,XXY) and one of X-linked recessive Amelogenesis Imperfecta. It appears that the X-chromosome not only plays some role in tooth size the degree of taurodontism increasing with increased number of X chromosomes), but probably also plays a role in enamel maturation.
