Fifteen infants were affected, for an incidence rate of one in 3,392 births. The affected teeth were the lower central incisors. The condition was more common in female infants. Two of the affected patients were twins. One patient each had Ellis—van Creveld syndrome, Pierre Robin syndrome, adrenogenital syndrome, cleft palate, and rickets. One mother each had pernicious anemia, vaginal infection, and diabetes mellitus.(AJDC 1986;140:249-251)
