Objective: The objective of this study was to determine the prevalence of ectopic eruption of intranasal teeth.
Design: This was a retrospective study, where records of children with repaired cleft lip and palate were analyzed.
Setting: The study was conducted at a large craniofacial center, the Hospital for Rehabilitation of Craniofacial Anomalies, USP, Bauru, São Paulo, Brazil.
Subjects: The sample consisted of 815 records from patients with bilateral cleft lip and palate (BCLP) and 1,495 records from patients with unilateral cleft lip and palate (UCLP). The age of the subjects was 5 to 10 years old and the groups included both males and females.
Results: The results showed that 0.61% of the children with BCLP and 0.40% of those with UCLP had an intranasal tooth. The prevalence of an intranasal tooth for the whole group was 0.48%, and it appeared to be more common in females.
