Calcium hydroxide formulation is frequently used in the treatment of root canals. We report a case where this formulation caused maxillary vascular embolism. A patient received an injection of calcium hydroxide formulation in to the right maxillary lateral incisor in a dental clinic. Immediately after, he presented with swelling of the surrounding gingiva, right cheek swelling, pain, and malaise. Necrosis of the right palate mucosa was observed. A CT image showed calcium hydroxide formulation confirmed to running from the greater palatal artery to the maxillary artery. We diagnosed maxillary vascular embolism caused by calcium hydroxide. On day 32, necrotic tissue of the palate mucosa was removed as much as possible under local anesthesia. On Day 233, the right upper 2 teeth were extracted and a radicular cyst was removed. On day 335, the redness on the right cheek skin almost disappeared, and the opening increased to 42 mm. The right oral and extraoral hypoesthesia remained, but was improving, and the right palate mucosa was completely epithelialized.

We clinicostatistically studied 102 cases of external dental fistula at the Department of Oral and Maxillofacial Surgery, Asahikawa Medical College during the past 18 years (from 1977 through 1994). The following results were obtained:<BR>1) The 102 patients comprised 49 males and 53 females. As for age, patients, in their twenties and thirties were most frequently encountered.<BR>2) The period from the onset of disease until the first visit at our clinic tended to be relatively long. The longest period was 13 years and the shortest several days. The average period was 16.9 months.<BR>3) The cheek area (48.0%) was the commonest site of external dental fistulae.<BR>4) External dental fistula arose more often in the mandibular region than the maxillary region, and was especially frequent in the mandibular molars and incisors.<BR>5) In many patients the involved teeth and the fistula were concurrently treated by surgery.
