In Reply.—Drs Mok and Suina are correct in their observation that the incidence of natal teeth is higher among infants of certain American Indian tribes. That there is racial variation in the incidence of natal teeth is beyond doubt. Magitot1 reported three cases of natal teeth in 17 578 births (one in 6000) at the Paris Maternity Hospital. Bodenhoff and Gorlin2 reported an incidence of at least one per 3000 births in the Danish population. In Britain the incidence is approximately one in 2000 births.3 The incidence of natal teeth among Chinese children in Hong Kong has been estimated to be one in 3400.4 Anderson5 reported an incidence of one in 800 births among the black population in Washington, DC. Gordon and Langley6 reported natal teeth in four of 407 American Indian infants delivered at a US Public Health Service Indian Hospital in Oklahoma.
