Background. Cleft lip and/or palate (CLP) is one of the most common types of craniofacial birth defects
Objectives. The aim of the current study was to investigate the prevalence of dental anomalies in children with CLP and classify them according to the type of cleft.
Material and Methods. This study consisted of 201 cleft patients including 131 males (mean age 12.3 ± 4 years) and 70 females (mean age of 12.6 ± 3.9 years). Dental anomalies including rotation, enamel opacity and hypoplasia, and shape malformation of central and lateral incisors were recorded. T-test and chi-square test were used for assessment of the data.
Results. Central incisor rotation was the most frequent anomaly observed. 57.2% of all the patients had central incisor rotation while only 15.4% of them had lateral incisor rotation. Chi square test showed that no specific association existed between anomalies and type of cleft. Enamel opacity and hypoplasia of central incisor was recorded in 40.3% and 35.8 of the patients respectively. 16.4% of the patients had peg shaped lateral incisors.
Conclusion. Vast majority of cleft lip and or plate patients had at least one dental anomaly and most of the dental anomalies were observed at the side of cleft. However, no association could be found between the type of cleft and dental anomalies.
