The incidence and types of dental trait anomalies found in individuals with cleft lip or cleft palate or both (cleft group), in siblings of the cleft group, and in a group of individuals without cleft lip or cleft palate (noncleft group) were compared. The cleft group had 1.02 anomalies per individual, the sibling group, 0.38; and the noncleft group, 0.17. The frequency of occurrence of thick-curved maxillary central incisors, incisal fissures, and missing teeth were significantly different among the three groups.
