title: Prevalence of odontogenic sinus tracts in patients referred for endodontic therapy.
abstract: The purpose of this study was to determine the prevalence of odontogenic sinus tracts in patients referred for endodontic therapy. Charts of 330 patients (393 permanent teeth) endodontically treated during a 10-month period were reviewed and data was collected. Among the 393 permanent teeth there were a total of 160 teeth with preoperative status of periradicular inflammation. Of 160 teeth with preoperative status of periradicular inflammation, 29 teeth (18.1%) had an odontogenic sinus tract, which correlates to almost one in five teeth with periradicular inflammation having a sinus tract.
