The incidence of oral clefts: a review.

We have reviewed epidemiological studies on the incidence of oral clefts in several regions of the world, but mainly in Europe. The incidence ranges from 1.0/1000 to 2.

Dental arch dimensions in unoperated adult cleft-palate patients: an analysis of 37 cases.

In surgically treated patients with clefts of the lip, alveolus, and/or palate, the vertical, transversal, and sagittal development of the maxilla is influenced by intrinsic, functional, and iatrogeneous (surgical) factors. To evaluate the effect of intrinsic and functional factors on dental arch development, we examined and compared unoperated adult individuals with different types of clefts. Dental casts of 37 Indonesian adults with unoperated unilateral clefts were studied: 15 subjects with unilateral cleft lip and alveolus (median age: 24 years) and 22 subjects with complete unilateral cleft of lip, alveolus, and palate (median age: 25 years).
