Tooth size in children with cleft lip and palate.

The mesiodistal and buccolingual dimensions of primary and permanent teeth were measured in 246 children with either isolated cleft palate or complete unilateral cleft lip and palate. The primary teeth of males with clefts were reduced in their buccolingual dimension compared to the control, while in females there were reductions in the mesio-distal dimension. There were no remarkable differences in the size of the permanent teeth in males with clefts. Females with clefts had reduced buccolingual dimensions of the permanent teeth, in both jaws.
