Incidence of cleft lips, palates rising

H C Slavkin. J Am Dent Assoc. 1992 Nov.

Abstract

About 1:700 live human births are affected by cleft lip and palate. Socio-economic factors--teenage pregnancies, pregnancies in women older than 35, increased consumption of teratogens during early months of pregnancy--have resulted in increased numbers of congenital malformations in the United States.
