title: Preradiotherapy dental extractions and health-related quality of life.
abstract: OBJECTIVE
  The aim of this study was to investigate the connection between preradiotherapy dental extractions and self-reported health-related QoL.
  
  
  METHODS
  Retrospective data on patients treated with radiotherapy for oropharyngeal cancer were pooled with the results of a cross-sectional survey.
  
  
  RESULTS
  Greater than eight preradiotherapy dental extractions, p16 negative status, female gender, and positive smoking status were associated with statistically significant reduced QoL.
  
  
  CONCLUSIONS
  Preradiotherapy dental extractions do not result in improved QoL and, in fact, may worsen it.
