摘　　要：目的比较中国人群不同孕期的妊娠期龈炎严重程度,以及细菌检出率的差异,为妊娠期龈炎的病因及防治研究提供相关依据。方法按照世界卫生组织1987年制定的口腔健康基本调查方法,对2010年10月～2011年3月在四川大学华西第二医院门诊孕检的13名妊娠期龈炎妇女行口腔临床检查及龈下菌斑细菌检测。结果不同孕期的SBI差异有统计学意义(P<0.05),其中以中孕组最高(0.93±0.45);细菌学分析结果发现,葡萄球菌属检出率在中孕组最高(P<0.05),链球菌属检出率在晚孕组最高(P<0.05)。结论由多项研究可知,孕期越长,龈炎患病率越高,但龈炎严重程度并不一定与患病率呈正相关;不同孕期的龈下微环境也会对葡萄球菌属与链球菌属的生长产生影响。Objective To compare the severity of pregnancy gingivitis and microbiological differences among various pregnancy stages,and provide evidence for prevention of pregnancy gingivitis.Methods According to the World Health Organization oral health survey basic method,13 pregnancy gingivitis women who took a pregnancy test between October 2010 and March 2011 were selected for oral clinical examination and subgingival plaque bacterium detection.Results SBI difference among various stages was significant（P〈0.05）,and the highest value（0.93±0.45） occurred in medium term.Bacteriological analysis showed that the prevalence of Staphylococcus was the highest in medium term,while the prevalence of Streptococcus was the highest in late term.Conclusion Many studies indicated that the prevalence of pregnancy gingivitis was positively associated with pregnancy period,but the relation between the severity and prevalence may not be positive.In different pregnancy stage,subgingival microenvironment played diverse roles in bacterium growth.
