目的：探讨菌斑指数（PLI）、龈沟出血指数（SBI）、牙周病变程度与妊娠的关系。方法：孕妇41例，同期未怀孕的健康女性40例（对照组）为对象。孕妇组孕3—5个月，对照组年龄与孕妇组匹配，检查记录PLI、SBI。结果：孕妇组的PLI、SBI均明显高于对照组（P〈0．05）。结论：妊娠是牙周疾病加剧的原因之一。

Objective： To explore the relationship between plaque index （PLI）, gingival sulcus bleeding index （SBI）, grades of periodontal lesions and pregnancy.
