A Case of Epulis Fibro-osteomatosa, with an Analysis by EPMA

An epulis with a formation of bone tissue occurred in the labial gingiva of maxillary left incisor region of a 28-year-old man. It consisted of hard fibroma, immature bone trabeculae and calcified bone tissue. An analysis by EPMA on the epulis tissue revealed that fibrous tissues was rich in S component while calcified bone tissue was rather poor in S

The Investigation Report on Current Status of Sports Consumption in Xiamen

通过对厦门市各阶层人士进行问卷调查 ,对体育经营企业的经营状况实地了解 ,分析厦门市体育消费现状。在 1998年厦门市家庭年均收入为 2 5 6 6 2元 ,年均体育消费为 75 4.95元。在体育消费种类上以体育物质产品消费为主 ,占消费总额的 6 5 .76 %。激发体育消费的因素主要有 :为了身体的健康、个人兴趣爱好等。影响体育消费的主要因素 :价格较高、没时间等。法人体育消费额达 10 0 0万元 (1998年 ) ,目前正呈良好的发展趋势。In order to investigate the sports consumption in xiamen, a total of 2000 questionnaire have been sent out with 1921 taken back. In 1998, the average family income per year is RMB 25662, while the average sports consumption is RMB 754.95. The expenditure on sports products is about the 65.76% of whole expense. The main factors for stimulating expenditure are for health, personal interests and hobbies. High prices and lack of time hamper people from consumption in Xiamen. Legal person sports consumption occupies a quite percentage and reaches 10 million

Electronmicroscopic studies on mucoepidermoid carcinoma : II. Calcified materials appeared in the stroma

Various globular materials appeared in the stroma of a low malignancy type of mucoepidermoid carcinoma (24-year-old woman: MDC 073-76) were studied by electron microscopy and by x-ray microanalytic method. Results were as follows: 1. These globular materials may be classified into five types. 2. Type I was electron-lucid vesicle with unit membrane, and was considered to have matrix vesicle-like functions. 3. Type II was electron-lucid globular materials with a electron-dense periphery, which had no evidence of calcification. 4. Type III was closed or round layer structure being composed of minute granular crystals. 5. Type IV was globular material, composed of both minute granular and needle-like crystals. 6. Type V was globular material only with developing needle-like crystals. 7. Type III and IV were mainly composed of P and Ca, therefore these structures were thought to be calcified. 8. It was considered that type V was similar to the matrix vesicle in initiation site of bone calcification, according to its ultrastructure and the results of analysis

Organisms Detected from the Oral Infectious Diseases : Examination in the last on year

Although serious infectious diseases have been decreased by means of the wide use of antibiotics, occurrence of opportunistic infection and increase of resistant bacteria have come serious problems. In order to reveal the species of organisms detected from oral infectious diseases, we investigated the 54 patients examined by the Department of Oral and Maxillofacial Surgery II, Matsumoto Dental College in the last one year. Some of the results were as follows. 1. Out of 35 cases in whom organisms were detected by needle aspiration, mixed infection were found in 27 cases (77.2%), and infection with anaerobes in 17 cases (48.6%). 2. Among 88 strains of organisms detected from the 35 needle aspirated cases, α-hemolytic streptococcus, anaerobic gram-negative rods and β-hemolytic streptococcus consisted 26.2%, 14.8% and 9.1%, respectively

Bone Grafting Performed to Two Cleft Lip and Palate Patients

Bone graftings were performed to two patients of cleft lip and palate. The first case was a 18-year-old female with nasal deformities, and was reconstructed using alveolar bone of the Г region. The second was a 14-year-old male with the floating premaxilla, and was reconstructed by Obwegeser\u27s osteotomy of the premaxilla and fixation with grafted iliac bone. Satisfactory results were obtained for facial deformities and functional disorders of them, and usefulness of bone grafts to cleft lip and palate patients was confirmed

Evaluation of Surgical Corrections Performed to Mandibular Prognathism of 17 Patients

Surgical corrections were performed on prognathism in 17 patients who were examined during the past 8 years in our department. The purpose of this study was to investigate the predominant cases of mandibular prognathism corrected by use of the Dal Pont-Obwegeser method, and to determire whether or not the period of preoperative orthodontic treatment, occlusion, particularly open bite, method of immobilisation, and rotation or displacement of condyle may considerably influence the prognosis (such as return to preoperative relationship). In conclusion, the Dal Pont-Obwegeser method was useful in achieving esthetic appearance, correct occlusion and proper function of the mandible. There have been no open bites nor relapse to date. However, open bite in preoperative relationship tended to intimate incisal occlusion within one year after the removal of arch bars and intermaxillary elastics or wires. A balanced occlusion in harmony with the restored masticating mechanism may not be easily established in open bite. Therefore stabilization may be necessary to be left for a period of more than one year namely critical period to arise postoperative complications. Arthrose was not observed even in cases in which the condyle was thought to be rotated, as the length of reduction to distal position was different on both sides, and radiography revealed a little dislocation of the position of condyle in mandibular fossa. In spite of the extreme care taken to not traumatize the inferior alveolar neurovascular bundle, numbness of one or both sides of the lower lip appeared in many cases, but it was not persistent anesthesia. These findings are of benefit to orthodontic and surgical cooperation in the treatment of cases of prognathism
