摘要
目的：了解重症老年卧床肺感染伴牙周病病人龈下菌斑中需氧致病菌的定植情况及其与肺感染致病菌的关系。方法：选我院重症卧床老年肺感染伴牙周病病人50名，记录其牙周状况、全身状况、痰培养结果，并选牙周炎症最重的1～2个观测牙进行龈下菌斑需氧菌培养和细菌分类计数，观察其龈下菌斑中需氧致病菌的定植情况及其与呼吸道致病菌的一致性，并分析其危险因素。结果：实验组龈下菌斑需氧致病菌检出率达23．96％，显著高于对照组（检出率7．45％，P=0．001），导致致病菌定植的危险因素主要包括：性别因素、住院天数、抗生素使用时间、体温、社区牙周指数（CPI）记分。实验组老年病人龈下菌斑与肺感染致病菌一致率为24％，其危险因素包括：性别因素、住院天数、抗生素的使用时间、体温、中性粒细胞分类、CPI记分、龈下菌斑中杆菌的百分比。结论：重症卧床老年病人的龈下菌斑较普通老年人更易定植需氧致病菌，且易被吸入导致呼吸道感染。这种细菌的定植和口腔肺脏细菌一致性与牙周炎症程度相关，也与性别、卧床时间、抗生素的使用、全身炎症程度相关。
AIM ：To observe the existence of aerobe in the subgingival plaque of aged sick in bed for a long time with lung infection and periodontitis, and find out the relationship between the existence of aerobe and lung infection. METHODS：Fifty patients who were in bed for a long time with lung infection and periodontitis were chosen. Their periodontal conditions, general conditions and the results of sputum culture were recorded. One or 2 teeth with the heaviest periodontal inflammation were chosen and the existence of aerobe in the subgingival plaque and the aerobic coherence between the subgingival plaque and lung infection were observed, and the risk factors were determined. RESULTS：The rate of aerobic existence of the trial people was 23.96%, which was higher than the control group （ 7.45 % , P = 0.00 1 ） , and the risk factors were gender, living time in the hospital, the time using antibiotic, and the score of community periodontal index（CPI）. There were 24% of the patients had the same aerobic in their subgingival plaque as in their lung tissue. The risk factors of aerobic coherence were gender, living time in the hospital, the time using antibiotic, proportion of neutrophil cell, score of CPI and the proportion of bacillus. CONCLUSION ： The aged sick who are in bed for a long time have more tendency to have aerobe in their subgingival plaque,and are more dangerous to get aspiration pneumonia. The existence and coherence of aerobe is correlated to the extent of periodontitis, gender,living time in the hospital,the time using antibiotic and the extent of general inflammation.
