Introduction: Oral clefts are common congenital malformations and their incidence varies among racial or ethnic groups. Despite the importance of congenital abnormalities, accurate statistical information about this disease is not available, so by using registry systems, enough information can be provided to decision makers to control this disease.Methods: The current study is a cross-sectional descriptive study of registry system data; that the data of 1461 patients with cleft palate have been analyzed in a period of 15 years. The collected data includes various variables along with geographical distribution.Findings: The findings of the present study indicate that the gender ratio of boys to girls is 1.3 to 1. In 4.79% of the mothers of babies with cleft palate, there was a history of underlying disease, of which hypothyroidism was the highest with 0.9%. In 54% of cases, parents were related. 58.31% of babies with cleft palate had other abnormalities in addition to this problem.Conclusion: The incidence rate of cleft palate is different in different parts of the world and in our country this variation may be affected by social and racial factors in different regions.
