Abstract Fifty-two patients who developed antro-oral fistula following tooth extraction were examined clinically and radiographically. Of these, 39 patients had only perforation of the antral floor and the other 13 had the tooth root pushed into the maxillary sinus. Maxillary sinusitis was present in 43 cases. The most frequent site of antro-oral fistula was the upper first molar, and the palatal root of the upper first molar was pushed into the antrum the most frequently. Our study suggested that most of the patients with antro-oral fistula had associated maxillary sinusitis before the extraction of the tooth. The highest risk of the occurrence of antro-oral fistula appeared to be at the time of extraction of the upper first molar associated with periapical and periodontal lesions.
