title: Tooth abnormalities of number and position in the permanent dentition of patients with complete bilateral cleft lip and palate.
abstract: OBJECTIVE
  To radiographically evaluate the prevalence of tooth abnormalities of number and position in the permanent dentition of individuals with complete bilateral cleft lip and palate.
  
  
  METHODS
  Cross-sectional retrospective.
  
  
  METHODS
  Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo, Bauru, Brazil.
  
  
  METHODS
  Two hundred five individuals with complete bilateral cleft lip and palate.
  
  
  METHODS
  Analysis of patient records and panoramic radiographs.
  
  
  METHODS
  Evaluation of hypodontia and supernumerary teeth and analysis of the position of the permanent maxillary lateral incisor in relation to the alveolar cleft.
  
  
  RESULTS
  Hypodontia was observed in 144 patients (70.2%), and the highest prevalence was observed for the maxillary lateral incisor. When both lateral incisors were present (43%), they were primarily located on the distal side of the cleft (25%). Supernumerary teeth were observed in 11.7% of individuals.
  
  
  CONCLUSIONS
  Patients with cleft lip and palate presented high prevalence of hypodontia and supernumerary teeth. The prevailing characteristics of their location may suggest the presence of a similar genetic component for the occurrence of hypodontia and cleft.
