A clinical survey was performed on 110 patients treated for dental sinusitis during the seven year period from September, 1969 to September, 1976. The following results were obtained.<br>1. There was no remarkable sex difference in incidense (51 males and 59 females), and no remarkable difference between right and left (52 left-sided and 58 right-sided).<br>2. The incidence was highest in 20s (32.7 %), followed by the 30s (31.8 %) and 40s (19 %).<br>3. The most frequent complaint was pus discharge from the oro-antral fistula (40%), followed by fetid rhinorrhea (22.7 %) and buccal pain (15.4 %).<br>4. The first molar was the highest causative (63.6 %), followed by the second molar (20 %) and second premolar (10 %).<br>5. There were 56 cases without pus in the nasal cavity. All of them were chronic type with oro-antral fistula. The pus might be discharged through the oro-antral fistula rather than middle meatus and this might be more accerelated by the irreversible change of the mucous membrane of the sinus.<br>6. X-ray findings revealed unilateral lesion in all cases, and ethmoid sinus inclusion was found only in 13.6%. It should be emphasized that the pathology was mostly confined to the maxillary sinus.<br>7. This disease is generally assumed to take an acute course, however, persistent pus discharge from the oro-antral fistula was found in as many as 61 cases in our series (55.4%). This indicates that a considerable number of cases turned into chronic changes.<br>8. Based on the clinical course and clinical findings, the clinical manifestations of this disease may be classified into the groups with and without dental extraction. The former is classified into the sub type with fistula and that with intrusion of tooth root. This method of classification is usefull for therapeutic purpose.<br>9. Eight methods are available for the treatment of this disease with otorhinological and dental approach combined.
