Conclusiones: El diente supernumerario es una anomalía que se presenta en los pacientes co n labio y paladar hendido, por lo que es pertinente el buen diagnóstico clínico y radiográfico para determinar su presencia, y así escoger la más apropiada opción de tratamiento según las necesidades del caso.Abstract Introduction: Patients with cleft lip and palate usually have dental abnormalities, particularly supernumerary tooth anomalies. The diagnosis and treatment are important, since it helps to minimise functional and aesthetic problems. Objective: The purpose of this study was to determine the prevalence of supernumerary teeth by radiographic analysis in patients with cleft lip and palate, who were treated in the Hospital Nacional de Ni ños, Costa Rica, during the period August 2009-July 2010. Methodology: The study was based on choosing a record of every 4 patients of the outpatient department, in order to review and analyse the orthopantomography. The statistical techniques used were frequency distributions, cross variables, an d comparison of means based on the analysis of variance. The minimum level of confidence for comparisons was 95%. Results: The total sample comprised 180 records with a confidence of 95% and a maximum permissible error of 5%. Almost one-third (32%) of the population had supernumerary teeth, particu larly the group of patients with cleft lip, alveolar and palate. Supernumerary teeth were 100% located on the maxillary arch, and mainly withi...
