Tooth germ transposition: report of cases.
Six patients with transposed tooth germ before root formation are reported in cases with cleft lip or palate. A boy with complete bilateral cleft lip and palate had a maxillary permanent canine displaced posteriorly in the vomer. A girl with cleft palate had an upwards and distally transmigrated maxillary canine. Two girls with cleft palate had a transposed maxillary canine with the first premolar. One patient had a maxillary second premolar migrated between the first and second permanent molar, and another had the germ of a supernumerary maxillary premolar between the first and second permanent molars. The follow-up findings concerning the development of the teeth and treatment are described; they are also discussed in the light of present theories on the etiology of tooth transposition.
