目的:评估妊娠期间牙周临床指标的变化,以探讨妊娠对牙周状况的影响。方法:选择30例无牙周炎症的妊娠早期妇女和20例无牙周炎症非妊娠妇女。其中妊娠组分别在妊娠早、中、后期进行3次临床牙周指数检查,包括牙周袋探诊深度(PPD)、出血指数(BI)、附着丧失(AL)、牙龈指数(GI)及菌斑指数(PLI);非妊娠组连续2个月检查牙周指数2次。结果:在维持良好的口腔卫生情况下,妊娠组孕早期的GI和BI明显高于非妊娠组(P<0.05)。同时,妊娠组GI和BI随妊娠时间的增加逐渐增加(P<0.05,P<0.001),但牙周附着水平无改变(P>0.05)。结论:妊娠可对牙龈炎症产生一定影响,但不影响牙周附着水平。
OBJECTIVE: To evaluate the changes of periodontal clinical parameters during pregnancy to explore the effect of pregnancy on periodontal status. Methods: 30 pregnant women with no periodontal inflammation and 20 non-pregnant women with periodontal inflammation were selected. The pregnancy group had 3 clinical periodontal index examinations in early, middle and late pregnancy, including the probing depth (PPD), bleeding index (BI), attachment loss (AL), gingival index (GI) Plaque index (PLI); Non-pregnancy group for 2 consecutive months to check the periodontal index 2 times. Results: GI and BI in pregnancy group were significantly higher than those in non-pregnancy group (P <0.05) while maintaining good oral hygiene. At the same time, GI and BI in pregnancy group increased gradually with the increase of gestation time (P <0.05, P <0.001), but the level of periodontal attachment did not change (P> 0.05). Conclusion: Pregnancy may have some effect on gingival inflammation, but does not affect the level of periodontal attachment.
