| 摘要 目的：观察口腔种植体周围细菌感染病原菌分布特点，分析细菌感染的危险因素。方法：选择360例于2018年7月~2021年5月在我院行口腔种植术的患者。根据是否发生口腔种植体周围细菌感染将患者分为感染组和未感染组。分离鉴定感染组病原菌种类。收集患者的临床资料，引起口腔种植体周围细菌感染的影响因素采用单因素及多因素Logistic回归分析。结果：360例患者中共有35例发生口腔种植体周围细菌感染，发生率为9.72%。共分离出49株病原菌，其中需氧菌14株（28.57%）、厌氧菌32株（65.31%）、有益菌3株（6.12%）；厌氧菌中又以口腔链球菌11株（22.45%）、牙龈卟啉单胞菌9株（18.37%）、产黑色素普雷沃菌7株（14.29%）为主。单因素分析结果显示：口腔种植体周围细菌感染的发生与吸烟史、慢性牙周炎病史、饮酒史、是否合并糖尿病、种植体周围牙槽骨情况以及口腔健康习惯有关（P＜0.05）；多因素Logistic回归分析显示口腔种植体周围细菌感染的危险因素是口腔健康习惯不良、种植体周围牙槽骨不良、合并糖尿病、有饮酒史、有慢性牙周炎病史、有吸烟史（P＜0.05）。结论：口腔种植体周围细菌感染的病原菌以厌氧菌为主，种植体周围牙槽骨不良、有慢性牙周炎病史、有吸烟史、合并糖尿病、饮酒史、口腔健康习惯不良是感染发生的危险因素，应针对上述因素进行适当干预。 |

| ABSTRACT Objective: To observe the distribution characteristics of pathogens of bacterial infection around oral implants, and to analyze the risk factors of bacterial infection. Methods: 360 patients undergoing oral implants in our hospital from July 2018 to May 2021 were selected. Patients were divided into infected group and uninfected group according to the occurrence of bacterial infection around oral implants. Isolate and identify the pathogen species of infection group. The clinical data of patients were collected, the influence factors of bacterial infection around oral implants were analyzed by univariate and multivariate Logistic regression. Results: There were 35 cases of bacterial infection around oral implants in 360 patients, and the incidence was 9.72%. A total of 49 strains of pathogenic bacteria were isolated, including aerobic bacteria 14 strains (28.57%), anaerobic bacteria 32 strains (65.31%), beneficial bacteria 3 strains (6.12%). Among anaerobic bacteria, 11 strains of oral streptococcus(22.45%), 9 strains of porphyromonas gingivalis(18.37%) and 7 strains of Melanin-producing Prevos (14.29%) were the main ones. Univariate analysis showed that the incidence of bacterial infection around dental implants was related to the history of smoking history, chronic periodontitis, drinking history, whether diabetes mellitus, alveolar bone around implants condition and oral health habits (P＜0.05). Multivariate Logistic regression analysis showed that the risk factors for bacterial infections around dental implants were poor oral health habits, poor alveolar bone around implants, with diabetes mellitus, drinking history, chronic periodontitis and smoking history(P＜0.05). Conclusion: The main pathogenic bacteria of oral implant infection are anaerobic bacteria. Poor alveolar bone around implant, history of chronic periodontitis, smoking history, with diabetes mellitus, drinking history and bad oral health habit are the risk factors of infection, and appropriate intervention should be carried out according to the above factors. |
