The purpose of this study is to obtain opinions from medical doctors about particular problems in dental treatment for medically compromised patients. Questionnaire was administered to 186 medical doctors in 24 hospitals which locate in the middle part of Nagano Prefecture. The answer was obtained from 43 percent of the doctors (n=87). The result revealed the fact that 30 percent of the doctors had experienced a complication of dental treatments. About 60 to 80 percent of the doctors accepted the standards of dental treatments for medically compromised patients which we described in the questionnaire, excepting the matters about timing for tooth extraction in the patients with myocardial infarction and the control level of blood sugar.

Recently, the number of medically compromised patients (MCP) is increasing in dental clinic. When MCP patients are practiced of dental treatments, it is necessary to consider the effect of general condition. This article was described the accommodation of MCP in 5 general private practices during 2 years. 733 MCP that were selected from 4, 884 patients were examined into classification of systemic medically disease and dental treatment with consultation for medicine. The results as follows
1) The ratio of medically compromised patients was 15.0%.
2) The most common medically disease was circulatory organ disease (356), diabetes mellitus (77), hepatic disease (48), cerebrivascular disease (33), hemapathy (8), etc.
3) MCP were treated of scaling (369), prosthodontic treatment (208), restoration (193), pulp extraction (180), denture (173), extraction (148), periodontal surgery (46), etc.
4) 173 cases were consulted for medicine, and the ratio was 23.6%.
Above mentioned, MCP were practiced various dental treatment in general practice. Until now, we did not encountered severe complications. However we should care for general condition with MCP, and must take knowledge and experience for MCP. So, training for general practice will be becoming most important work in dentistry. Therefore, dentist of oral and maxillofacial surgery who had expert knowledge of MCP dentistry should cooperated the training.

Three cases of fracture of the madibular condyle in patients under treatment of epilepsy is reported. All cases were suffered from the trauma due to falling down by epileptic seizure and visited our branch complaining masticatory disturbance. They were treated with nonsurgical management and satisfactory result was produced.
The first case was a 33-year-old male patient (Fig. 1). The CT examination showed that the fracture seperated left condylar head sugitally. As smaller segment, the inner pole was displaced anteriorly with the contraction of left lateral pterygoid muscle. The spasmodic tonic contraction of the muscle by the epileptic seizure was considered as one of the causative factors of the longitudinal fracture of condyle. Because of mental retardation he could not accept tight intermaxillary fixation with metal wire ligamentation even a day, and broke down the arch bars. By means of intermaxillaly elastic traction about two weeks under frequent observations on his occlusion and early training of mouth opening brouht a good result.
The second case was a 32-year-old male patient (Fig. 2). He was suffered from fractures of right mandibular angle and left condyle. The condylar fracture was simple crack with no deviation of fragments, so that the detection of the lesion at first visit was difficult. About four weeks after intermaxillaly fixation, the ligamnets were removed. His occlusion and TMJ function got well. However, inflammation and hypergrowth of gingiva was occured due to insufficient oral hygiene during the intermaxillary fixation. The abnormal state of gingiva was diminished after removal of arch bars and with sufficient tooth brushing. Soon after, he suffered from left TMJ trouble due to epileptic seizure but his occlusion and masticatory function were kept in safety.
The third case was a 54-year-old male patient (Fig. 3). His fracture occured in the right condyle with deviation of fragments. He was treated with intermaxillary fixation. In the clinical process he hit him on his face due to epileptic attack. Despite of such trouble the clinical result was good.
Through management of these three cases it was suggested that nonsurgical management, in compairing with surgical one, has several advanteges in the case of the treatment of condylar fracture in patients under treatment of epilepsy. The largest advantage is easiness of correction of malocclusion brought with epileptic attack during the treatment of fracture.

The Morbidity status of children who were examined at the Department of Oral and Maxillofacial surgery Tokyo women's Medical University School of Medicine in the period of four years from 1994 to 1998 was evaluated.
Among 1, 670 child patients in total there were 566 children identified as morbid and the morbidity rate was 33.9%.
Mean diesease affliction was 1.21 per child. As for other disease prevalence apart from dentistry, the rate of circulatory organ related diseases was most at 30.8% being then followed in order of urinary organs, respiratory organs and neurological disease. At our department about half of all diseases identified were dental diseases at the rate of 60.1%, and then being followed by traumas, and inflammation. Most treatments provided were conservative and prosthetic treatments, then followed by the provision of brushing instruction and scaling.
