To investigate the possible association between mother's periodontal status and preterm low birth weight (PLBW) in Beijing.
The periodontal status of 83 women who bore a preterm low birth weight infant (PLBW group) and 44 women who bore a normal birth weight infant (NBW group) within two years in four hospitals in Beijing were evaluated. These women were all generally healthy. The clinical periodontal parameters including plaque index (PLI), probing depth (PD), attachment loss (AL) and bleeding index (BI) recorded.
The percentages of PD > or = 4 mm sites, AL > or = 2 mm sites and BOP(+) sites in two groups were 8.1% vs 6.9%, 12.8% vs 6.1% and 70.4% vs 66.9%, respectively, which showed significantly higher in PLBW group than in NBW group(P < 0.01, P < 0.001, P < 0.01).
There was possible association between mother's periodontal status and preterm low birth weight in the investigated area. Poor periodontal status may be one of the risk factors of PLBW.
调查北京地区母亲的牙周状况与早产低体重之间的可能关联。
对北京四家医院两年内分娩早产低体重儿的83名妇女（早产低体重组）和分娩正常体重儿的44名妇女（正常体重组）的牙周状况进行评估。这些妇女总体健康。记录临床牙周参数，包括菌斑指数（PLI）、探诊深度（PD）、附着丧失（AL）和出血指数（BI）。
两组中探诊深度≥4mm部位、附着丧失≥2mm部位和探诊出血阳性（BOP(+)）部位的百分比分别为8.1%对6.9%、12.8%对6.1%和70.4%对66.9%，早产低体重组显著高于正常体重组（P<0.01，P<0.001，P<0.01）。
在调查地区，母亲的牙周状况与早产低体重之间可能存在关联。牙周状况不佳可能是早产低体重的危险因素之一。
