title: Tooth loss and associated factors in patients with coagulopathies in the State of Paraíba, Brazil.
abstract: BACKGROUND
  The most common and best known hereditary coagulopathies are hemophilia A and B followed by von Willebrand Disease.
  
  
  OBJECTIVE
  This study aimed to estimate the prevalence of tooth loss and investigate its association with demographic and socioeconomic data, as well as to discuss self-reported oral morbidity and use of health services by patients with coagulopathies treated in blood centers in Paraíba, Brazil.
  
  
  METHODS
  This was a quantitative cross-sectional epidemiological survey. Data was collected in the period from October 2011 to July 2012 by clinical examination and by assessing interviews using a semi-structured questionnaire. The findings were analyzed by descriptive and inferential statistics with the level of significance (α) being set at 10%.
  
  
  RESULTS
  One hundred and six, predominantly male (88.8%), patients with coagulopathies were evaluated. The ages ranged from one to 59 years. Most patients were of mixed race (61.3%), most reported family incomes between R$ 501.00 and R$ 1500.00 (49.1%), and most had not completed elementary school (37.1%). Hemophilia A was found in 76.4% of the cases. The prevalence of dental caries among individuals was 50.0% predominantly in the 13- to 19-year-old age range (66.7%). As regards to tooth loss, teeth were missing in 35.1% of the study participants.
  
  
  CONCLUSIONS
  Tooth loss is high in this population. Males with severe hemophilia A, those who use fluoride and have a good or very good perception about their last dental appointment have a reduced chance of losing their teeth.
