牙周疾病作为一种亚临床和持续的感染源,可以造成系统性的炎症反应,增加不良妊娠结局。目前很多研究表明,牙周疾病的严重程度与胎儿早产、低出生体质量呈正相关,与死胎及围生儿死亡显著相关,牙周疾病的存在和严重程度显著增加了子痫前期和妊娠期糖尿病的发生风险,积极合理的治疗不会增加胎儿的不良结局,并可能在一定程度上改善母儿预后。 Periodontal disease as a subclinical and persistent source of infection can cause a systemic inflammatory response and increase adverse pregnancy outcomes. At present, many studies have shown that the severity of periodontal disease is positively correlated with fetal preterm birth and low birth weight, significantly associated with stillbirth and perinatal mortality, and the presence and severity of periodontal disease significantly increases preeclampsia and gestational diabetes The risk of active and reasonable treatment will not increase the adverse fetal outcomes, and may to some extent improve the prognosis of maternal and child.
