摘　　要：目的比较分娩早产低出生体重儿(PLBW)的孕妇与足月妊娠正常分娩新生儿(NBW)孕妇的牙周状况及牙周病的发生率,探讨牙周病与PLBW的关系。方法随机选取分娩PLBW的孕妇206例为研究组,选取同期分娩NBW的孕妇209例为对照组,检测两组孕妇的牙周状况,记录菌斑指数(PLI)、探诊深度(PD),临床附着丧失(CAL)和出血指数(BI),并计算牙周炎位点率(PD>3 mm,CAL>2 mm)及牙周病的发生率。结果分娩早产低出生体重儿的孕妇牙周炎位点率(3.3%)和牙周病发生率(81.1%)明显高于对照组(1.4%,35.9%),差异有显著性(P<0.01);牙周炎位点率与孕周和新生儿体重均呈负相关系(P<0.05)。结论牙周病可能是PLBW发生的危险因素。Objective To evaluate periodontal conditions and prevalence of periodontal diseases in pregnant women who had normal-birth- weight （NBV/） and pretenn-low-birth-weight （PLBW） delivery outcomes. Methods 206 women who gave birth to PLBW and 209 women who had normal delivery were recruited postpartum in this case-control study. Periodontal measurements included plaque index （ PI）, probing pocket depth（PD）, clinical attachment loss（CAL）, bleeding index（BI）, the percentage of periodontitis sites（ PD 〉 3 m m, C AL-2mm） and prevalence of periodontal diseases. Results The percentage of periodontitis sites （3.3%） and prevalence of periodontal diseases （81.1%） were significantly higher in the PLBW group than those in the NBW group （ 1.4% ,35.9% ） （P 〈 0. 01）. Significant negative correlations were observed between percentage of periodontitis sites and the gestational age at delivery as well as neonatal body weight （P 〈0.05 ）. Conclu- sions There may be a possible link between periodontal diseases and preterm-low-birth-weight delivery outcomes.
