title: Meta-analysis of the etiology of odontogenic maxillary sinusitis.
abstract: OBJECTIVE
  To identify and evaluate the frequency of the different odontogenic conditions that may lead to maxillary sinusitis.
  
  
  METHODS
  An observational and retrospective meta-analysis was carried out on 770 cases of maxillary sinusitis obtained from a literature review of 15 articles.
  
  
  RESULTS
  Maxillary sinusitis most commonly manifests itself as chronic maxillary sinusitis. It is more common in females and is most often diagnosed in the fifth decade of life. The teeth most predominantly affected are the molars, with the first molar tooth being the most frequently involved. The principal etiological factor is extraction.
