The degree of injury depends on the chemical, its concentration, duration of contact, and the natural penetrability and resistance of the tissues involved. Chemicals do not usually “burn”in that they do not cause destruction by hyperthermic activity. Rather, they damage tissue by causing coagulation of protein by one of several processes, reduction, oxidation, desiccation, corrosion, or vesication. Paraquat(Gramoxon) is the most frequently agricultural chemicals that induce the severe toxic reactions onto the organs of human body in Korea. The toxic reaction are composed of pulmonary edema and fibrosis, formation of hyaline membrane, inflammatory reaction and bleeding tendency, owing to the cell damage by the production of superoxide radicals. The contents of essential treatment in paraquat intoxication are commonly airway and breathing maintenance, gastric lavage, much hydration and diuresis, hemoperfusion and medications for the removal of the chemicals and the prevention of various complications. The sedative oral dressings, such as, orabase ointment application, warm saline gargling, lidocaine viscous gargling and oral gargling by the mixed solutions(tetracycline, prednisolone and 10% dextrose water) are important for the improvement of chemical oral mucositis and the comfortable feeding of diet. The authors managed properly two cases of oral chemical mucositis that were occurred by the incorrect use of agricultural chemicals(paraquat) and report the cases with the review of literatures about care of the chemical intoxication and oral mucositis.

분자생물학적 기법을 이용한 악골 골수염 병소의 세균 동정

Abstract: The purpose of this study was to isolate and identify the bacteria in osteomyelitis lesion of 3 patients. Two lesions were due to the post-infection after extraction. The other was resulted from mal-fixation of both sides of mandibular angles. Pus samples were collected by needle aspiration from the lesion and examined by culture method. Bacterial culture was performed in three culture systems (anaerobic, CO2, and aerobic incubator). Identification of the bacteria was performed by 16S rRNA gene cloning and nucleotide sequencing method. Our results showed that Streptococci species was predominantly isolated in both lesions of extraction socket. Only one species (Proteus vulagris) was detected in lesion of mandibular angle. This study was not sufficient to identify the causative bacteria in those osteomyelitis. However, our data may be offered the clue to solve the problem.

악교정수술 환자에서 교합기 석고 모형과 측면두부방사선사진의 교합평면에 관한 비교 연구

Abstract: The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3-dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed, 1. The mean occlusal plane angle in cast-mounted articulator was 13.5.(SD±5.4). 2. The mean occlusal plane angle in cephalogram was 10.4.(SD±4.3). 3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3.(SD±4.6). According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram. And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

신장 이식 환자에서 발생한 구강내 카포시 육종;증례 보고

Abstract: Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi's sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi's sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi's sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi's sarcoma on the hard palate in the kidney transplantation patient.

주용 출혈성 질환자에게 치성감염 관리에 관한 임상적 연구

Abstract: This is a retrospective study on the care of odontogenic infections in admission patients with major bleeding disorders. The study was based on a series of 514 patients treated at Dong San Medical Center, Wonju Christian Hospital and Il San Health Insurance Hospital, from Jan. 1, 2000, to Dec. 31, 2000. The obtained results were as follows: 1. The cardiovascular disease and renal failure were next in order of frequency. But, there was the most frequent dental consultation in the liver disease, owing to the many odontogenic infectious diseases. 2. Male prediction (66.3%) was almost existed in the odontogenic infectious patients with major bleeding disorders. But, there was slight female prediction (53.4%) in the cardiovascular disease. 3. The most common age group of the odontogenic infectious patients with major bleeding disorders was the fifty decade(27.2%), followed by the forty, sixty & thirty decade in order. 4. In the contents of chief complaints on the odontogenic infectious patients with major bleeding disorder, peak incidence was occurred as toothache (42.2%), followed by intraoral bleeding, ulcer pain, dental extraction in order. 5. In the diagnosis group of odontogenic infectious diseases, periodontitis, pulpitis and periapical abscess were more common. 6. In the treatment group of odontogenic infectious diseases, the most frequent incidence (44.2%) was showed in primary endodontic drainage(pulp extirpation, occlusal reduction & canal opening drainage) and followed by the incision & drainage, the medications & oral hygiene instruction, scaling, indirect pulp capping in order.

구개피판을 이용한 구개결손부 수복

Abstract: The Reconstructive techniques of palatal defect are palatal island flap, palatal mucoperiosteal expansion, buccal flap, tongue flap, pushback palatoplasty, free flap and so on. We report a reconstruction of palatal defect using palatal flap. Excellent results were obtained by palatal connective tissue island flap and split thickness pedicle flap. Healing of defect occured rapidly. There were no postoperative complications except dull pain.

하악골에 발생한 동정맥 기형의 혈관 색전술에 의한 치험례

Abstract: Mandibular arteriovenous malformations(AVM) are relatively rare and potentially life threatening lesions. Surgical treatment consists of wide resection of the mandible, which is difficult and potentially hazardous due to significant blood loss during surgery. Therefore, some authors advocate that transvenous embolization may be a safer and more effective method in the treatment of mandibular AVM. We report a treatment case of mandibular AVM in a 9-year-old-girl for episodes of spontaneous bleeding for 6 days using by selective transarterial embolization ,direct puncture embolization and microcoil embolization.
