title: Radiographic study of patients with ectodermal dysplasia and partial.
abstract: OBJECTIVE
  To investigate the association between gender and type of cleft with hypodontia and to verify if the presence of the cleft interferes with hypodontia of one or more type of teeth in patients with ectodermal dysplasia attending the Hospital for Rehabilitation of Craniofacial Anomalies (HRCA), University of São Paulo (USP).
  
  
  METHODS
  Panoramic radiographs of 54 patients of both genders (29 males, 25 females), from the files of the oral radiology sector of HRCA/USP, presenting with ectodermal dysplasia and cleft lip and/or palate were evaluated by radiographic observation of hypodontia of one or more types of teeth.
  
  
  METHODS
  We performed descriptive statistics and statistical analysis by Fisher test.
  
  
  RESULTS
  Hypodontia was observed in 50% of females and 50.88% of males; 50% for cleft palate and 50.59% for complete cleft lip and palate. Only 22.22% of patients with cleft palate and 6.67% with complete cleft lip and palate presented with hypodontia of one type of teeth, whereas 77.78% of cases with cleft palate and 93.33% with complete cleft lip and palate displayed hypodontia of more than one type of teeth.
  
  
  CONCLUSIONS
  Based on the present methodology, there were no statistically significant differences in hypodontia of one or more types of teeth between genders or types of cleft.
