Prevalence of dental anomalies in children with cleft lip and unilateral and bilateral cleft lip and palate

Aim To examine the prevalence of different types of dental anomalies in childreh with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate. Materials and methods A sample of 90 patients (aged 14-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to cleft type: (1) Unilateral Cleft Lip-Palate, Bilateral Cleft Lip-Palate, and (3) Cleft Lip, Intraoral exams, panoramic radiographs and dental casts, were used to analyse the prevalence of the various dental anomalies included in this study Results There were no statistically significant differences between patients with cleft lip; unilateral deft lip and palate and bilateral cleft lip and palate. The congenital absence of the deft-side lateral incisor was observed in 40% of the sample, and a total of 30% patients showed supernumerary teeth at the incisors region. Second premolar agenesis was found in 44% of patients, whereas in 18.9% of the sample there was an ectopic dental eruption. Lateral or central incisors rotation was noted in 31.1% of the sample, while shape anomaly lateral incisor microdontia, and enamel hypoplasia were detected respectively in 25.6%, 5.6% and 18.9% of cleft patients. Conclusion High prevalence of different dental anomalies in children with deft lip and unilateral and bilateral deft lip and palate has been confirmed. This study in particular, shows the presence of ectopic and rotated teeth in the deft area.
