Background: Orofacial clefts (OFC) are the most common congenital malformation of the craniofacial skeleton. Attempts have been made to correlate the components of maternal diet as triggers for the development or prevention of OFC.

Objective: To analyze nutritional status as a predictive factor for the development of cleft lip and palate in an Amazonian population.
