Schwannoma occurs everywhere neural tissue exists, but it is relatively rare in oral regions. It orally originates mostly in the tongue and very little in the lips. Recently we experienced a case of schwannoma arising in the left lower lip. The patient was a 73-year-old man and visited our hospital with the chief complaint of a lower lip. The tumor was excised under local anesthesia, and it was found to be an elliptical mass with a capsule measuring 35 × 20 × 20 mm. From both clinical and light microscopical findings it was diagnosed as schwannoma (Antoni A and B type) and was compared with other reports of schwannomas which had been already reported in Japan. From electron microscopical and immunohistochemical findings the origin of the tumor was suggested to be schwann cells in the present study.

To investigate the extent of oral diseases in the aged, a dental examination was conducted in combination with medical examinations of elderly inhabitants of Miyako district, Okinawa pref.Abnormal oral findings were noted in 1, 655 (29.19 %) of 5, 670 examinees. The incidence of oral disease tended to increase with age. Among the oral disease detected, oral mucosal diseases showed the highest frequency. Suspected malignant tumors were found in 0.14%, benign tumors in 4.36 %, leukoplakia in 1.29 % and diseases presumably due to insufficient oral care by dentists or patients in 8.77 % of the examinees. Evaluation of the state of disease revealed that a higher proportion of systemic diseases were under medical treatment as compared with oral diseases. Further detailed examination was indicated in 50 (0.88 %) examinees with oral diseases.

Septic pulmonary embolism is a rare condition, the common sources of which are bacterial endocarditis and infected venous catheters. Septic pulmonary embolism ascribed to dental infection is extremely rare. The present report describes a case of septic pulmonary embolism attributed to periapical periodontitis in a 39-year-old patient, who was admitted with persistent toothache, fever, and chest pain. Chest CT showed a feeding vessel sign and a target sign. A panoramic radiograph of the left maxillary bone showed alveolar bone loss in a horizontal pattern typical of periodontitis and periapical periodontitis. The patient was treated with intravenous antibiotics and teeth extraction. To our knowledge, only 4 cases of septic pulmonary embolism ascribed to dental infection have been reported in the English literature. These patients repeatedly developed dental infections but did not receive appropriate dental treatment including extraction of the causative teeth, leading to the development of septic pulmonary embolism. This paper may contribute to the limited clinical knowledge base regarding septic pulmonary embolism ascribed to periapical periodontitis. Effective oral care and removal of the primary source of infection, including extraction of the causative teeth, are important to prevent septic pulmonary embolism.

One hundred forty-six teeth on the fracture lines of mandibular fractures (85 patients) treated at the Department of Oral and Maxillofacial Surgery, Shimane Medical University Hospital, from 1980 to 1998, were clinicostatistically analyzed. The results were as follows:1. The age of patients was widely distributed. The peak incidence was the second and third decades (74.1%). The male and female ratio was 4 to 1.2. The cause of fracture was 26 cases (30.6%) in the traffic accident, 21 cases (24.1%) in falls, 17 cases (20.0%) in sports, 10 cases (11.7%) in beating, 9 cases (10.6%) in work accidents and 2 cases (2.4%) in others.3. Teeth on the lines of mandibular fractures were found in 35 teeth (20.4%) in the wisdom teeth and in 34 teeth (23.4%) in the canine teeth and in 77 teeth (56.2%) in the others.4. Seventy-three teeth (85.6%) out of all teeth were preserved without teeth extractions.5. Teeth on the mandibular fracture lines could be classified into four types (I-IV) according to our original classification ; type I was 19.2%, type II was 49.4%, type III was 19.2%, and type N was 12.2%.6. We investigated whether the teeth on the lines of the mandibular fractures were preserved or not after treatments-91.3% of the teeth had been preserved for more than one year after treatments.
