摘　　要：目的:观察青春期牙龈炎患者龈下菌斑中牙周致病菌的变化特点,并分析其相关因素。方法:选取2014年3月至2015年9月在我科接受治疗的80例青春期牙龈炎患者为研究对象(观察组),同时抽取50例某校初中生作为对照组。比较两组受检者牙周状况和龈下菌斑致病菌的检出率,并分析影响青春期龈炎患者龈下菌斑检出率的相关因素。结果:1、2和3级青春期龈炎患者的牙龈指数、菌斑指数和龈沟出血指数均高于对照组(P<0.05),且3级龈炎患者的上述指标高于2级龈炎患者,2级患者上述指标高于1级患者,差异具有统计学意义;各级青春期龈炎患者龈下菌斑中致病菌牙龈卜啉单胞菌(Pg)、中间普氏菌(Pi)、福赛斯坦纳菌(Tf)和齿垢密螺旋体(Td)的检出率均高于对照组,2、3级龈炎患者上述致病菌的检出率均高于1级龈炎患者,而2、3级龈炎患者间差异无统计学意义;各组患者致病菌含量由高到低分别为3级龈炎组、2级龈炎组、1级龈炎组和对照组;龈炎患者的年龄、龈炎程度、吸烟、牙龈指数、菌斑指数、龈沟出血指数与Pg、Pi、Tf和Td的检出率显著正相关,而性别与上述致病菌的检出率无明显相关性。结论:青春期牙龈炎患者牙周状况较差,与龈炎程度相关;中重度龈炎患者龈下菌斑检出率较高,致病菌检出率与年龄、龈炎程度、吸烟、牙龈指数、菌斑指数、龈沟出血指数显著正相关。Objective： To observe the changes characteristics of periodontal pathogens in puberty gingivitis subgingival plaque, and analyze its related factors. Methods： 80 puberty gingivitis patients treated in our department from March 2014 to September 2015 were selected as study group,and 50 cases drawn Junior School students were selected as control group. The periodontal status and the subgingival plaque bacteria detection rate of the two groups were compared,and the relevant factors influencing puberty gingivitis subgingival plaque detection rate were analyzed. Results： The puberty gingivitis gingival index,plaque index and bleeding index of grade 1,2,3 patients were higher（ P〈0. 05）,and the indexes of grade 3 patients were higher than those of grade 2 patients,the gingivitis indicators of grade 2 patients were higher than grade 1 patient,the difference was statistically significant. The Pg,Pi,Tf and Td detection rates of pathogenic bacteria in puberty gingivitis patients were higher than those in the control group. The bacteria content of the patients from high to low： grade 3 gingivitis group,grade2 gingivitis group,grade 1 gingivitis group and control group. The above pathogens of grade 2,3 gingivitis patients were higher than those of grade 1 gingivitis patients,and there were no significant differences between grade 2 and grade 3 patients. Gingivitis patient＇s age,gingivitis,smoking,gingival index,plaque index,bleeding index were significantly positively correlated with the detection rate of Pg,Pi,Tf and Td,but gender had no significant correlation with the above pathogens detection rate. Conclusion： Puberty gingivitis patients with poor periodontal condition,which is correlated with gingivitis. The subgingival plaque detection rate of moderate-severe gingivitis patients is higher,pathogen detection rate is significantly positively correlated with age,gingivitis,smoking,gingival index,plaque index,bleeding index.
