Prevalence of odontogenic sinus tracts in patients referred for endodontic therapy.
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.
