OBJECTIVE: To describe the location and presence of permanent teeth in nonsyndromic complete bilateral cleft lip and palate patients from the Manitoba Centre for Craniofacial Difference. MATERIALS AND METHODS: Records of 1570 patients dating back to 1958 were assessed in this retrospective chart review. RESULTS: Thirty-eight patients met the inclusion criteria, providing 76 cleft site teeth: A tooth on each side of the cleft was considered to have developed from a single lateral incisor tooth bud. The pattern M was assigned when a tooth was found mesial to the cleft, D when distal, MD when mesial and distal and AB if none was found. Pattern M was noted 9.2% of the time; D, 47.4%; MD, 5.3%; and AB, 38.2%. Teeth outside the cleft site: In the maxilla, agenesis occurred in 11.9% of second premolars and 10.5% of central incisors. In the mandible, agenesis occurred in 4.0% of second premolars, 2.6% of lateral incisors, 2.6% of central incisors, and 2.6% of second molars. CONCLUSIONS: The lateral incisor was most commonly found distal to the cleft. Agenesis of the lateral incisor and teeth outside the cleft were more common than in noncleft populations.
