Abstract
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

Subjects
The sample consisted of 815 records from patients with bilateral cleft lip and palate (BCLP) and 1495 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.
