title: An unusual triad: microdontia, taurodontia, and dens invaginatus.
abstract: A 12 1/2-year-old white boy was examined and found to have permanent teeth that were smaller than those of the average adult. The microdontia was accompanied by taurodontia of the mandibular molars and several teeth with dens invaginatus. The patient was normal in appearance and had no other illness. The pedigree was compatible with X-linked recessive inheritance.
