摘要：The most frequent major congenital craniofacial defect is clefts of the upper lip and palate, which occur in one out of every 700 babies. Despite the fact that inheritance may play a role, cleft lip and palate is a multifactorial aetiology with potential contributing factors such as chemical exposures, radiation, maternal hypoxia, teratogenic drugs, nutritional deficiencies, particularly folic acid, physical obstruction, or genetic influences. According to one popular explanation, clefting occurs when many etiological causes combine to raise one individual above the point where the fusion mechanism fails. This study focuses on comparing the incidence of unilateral cleft lip between two populations among patients of saveetha dental college. The study population involves patients from two populations, patients from Tamil nadu and Andhra Pradesh. The data of the patients were extracted from patient records from DIAS. From the current study we infer that 75% of the cleft lip patients are below the age of 1 year, 54% of the patients were males and 46% were females, 67% of the patients were from Tamil Nadu and 37% were from Andhra Pradesh. The findings suggest a higher incidence of cleft lip population in Tamil Nadu than Andhra pradesh. It was also found that prevalence of cleft lip was seen more in males than in females.
