312例经皮冠状动脉介入治疗的冠心病患者的心电监护拔牙的临床回顾研究

目的:观察分析经皮冠状动脉介入治疗(PCI)的冠心病患者局部麻醉和拔牙过程中的血压、心率、心电图的变化以及并发症的处理,为此类患者安全施行拔牙手术提供参考。方法:全程心电监护312例PCI术后的冠心病患者的拔牙,术前、术中根据心率、血压、心电图等情况给予相关的治疗,记录麻醉术前、中、后和拔牙术前、中、后的血压、心率的变化,进行对比分析。结果:303例患者完成手术,其中62例术中出现需要处置的心肌缺血、血压升高及心率失常等改变。9例因并发症停止拔牙治疗。麻醉前、中、后及拔牙前、中、后收缩压、舒张压和心率的变化有显著性差异,P<0.05;拔牙后10分钟的收缩压、舒张压和心率较麻醉前显著下降,P<0.01。结论:在术前积极准备及沟通、术中严密心电监护下,大多数经皮冠状动脉介入治疗的冠心病患者可以安全地完成牙齿拔除术。     

Oral microorganisms and cardiovascular disease

The list of etiological factors for cardiovascular disease is long, complicated, intertwined, and yet to be completed. This paper will evaluate the current evidence for the pathogenic role of certain microorganisms, including those of the oral cavity, in the etiology of cardiovascular disease.     

Oral health and cardiovascular disease in Sweden

OBJECTIVE: The purpose of the present study was to assess the relation between dental health and cardiovascular disease in an adult Swedish population. MATERIAL AND METHOD: A questionnaire was sent to 4811 randomly selected Swedes. It contained 52 questions about dental care habits, oral health, cardiovascular disease and their socio-economic situation. Odd ratios for all cardiovascular diseases (CVD) and the subgroup myocardial infarction, stroke and high blood pressure were calculated with a logistic regression model adjusted for age, gender, smoking, income, civil status and education. These ratios were calculated for subjects > or =41 years since few people suffer from CVD before this. RESULTS: The national questionnaire was answered by 2839 (59%) people between 20-84 years of age and, of them, 1577 were 41 years of age or more. We found a significant association between self-reported bleeding gums (odds ratio 1.60, p=0.0017), presence of dentures (odds ratio 1.57, p=0.0076) and known CVD, which has also been reported in international studies. However, no association between loose teeth, deep pockets and known CVD was detected. CONCLUSION: The results indicate that oral health and, especially gingival inflammation is associated with CVD.     

Reasons for extraction of permanent teeth in Jordan

This investigation was carried out to determine the reasons for extraction of permanent teeth in Jordan. A random sample of 200 Jordanian Dentists (1:10) were asked to record reasons for the extraction of permanent teeth during a two week period. Of the 139 dentists responding, only 97 dentists extracted teeth during the study period. A total of 934 teeth were extracted from 582 patients, of these 33.4 per cent were extracted for periodontal disease, and 27.6 per cent because of caries and its sequelae. The study suggests caries and its consequences affected tooth loss throughout life while the rate of tooth loss due to periodontal disease increases with age.     

Traditional orthodontic treatment, orthodontic appliances, and extraction for orthodontic treatment do not appear to cause TMD

Oral cancer and sex, Why do females do better?

Analysis of a group of 194 patients with squamous cell carcinoma of the oral cavity has shown that the survival figures for females is significantly better than that for males. The material has been analyzed in an attempt to explain this difference. The females in this series did not attend at an earlier stage, at a younger age or with more highly differentiated tumours. The site distribution was similar for the two sexes but the improved survival for females was found particularly with tumours of the cheek and commissure region and the lower alveolus. Various possible explanations are discussed and it is suggested that the host response of females to intra-oral cancer is different to that of males.
