Abstract: Objective To survey on periodontal status of pregnant women and pregnant outcome,and to explore its possible relationship between periodontal infection and preterm birth.Methods 674 pregnant women were selected in Wuxi Maternal and Child HealthCare Hospital during 2012 JanuaryDecember.Women were given periodontal examination.OHIS,SBI,PD and CAL were recorded and pregnant outcome was tracked.The result was analyzed with chisquare test,t test and Spearman correlation analysis.Results ①Periodontitis prevalence of preterm women (36.1%) was higher than that of fullterm pregnant women (21.4%).There was a significant difference in gestational age and birth weight between the two groups (P<0.01); ②OHIS,SBI,PD,CAL of preterm group were higher than fullterm pregnancy group (P<0.05); ③Maternal periodontal index of OHIS,PD,CAL and gestational age was negatively correlated (P<0.05).Conclusions There is a correlation between maternal periodontal infection and preterm birth.Periodontitis among pregnant women is a risk factor for preterm birth.We must pay more attention to oral health care of these pregnant women.
