概括
这项门德尔随机化研究发现牙周炎和大多数不良妊娠结果之间没有因果关系. 然而,慢性牙周炎可能与低出生体重有关,尽管需要进一步的研究.
科学领域:
- 生殖健康 生殖健康
- 牙周病学 牙周病学
- 遗传流行病学遗传流行病学
背景情况:
- 牙周炎是一种常见的口腔感染.
- 负面的妊娠结果 (APO) 对母亲和婴儿的健康构成重大风险.
- 牙周炎和APO之间的潜在因果关系需要严格调查.
研究的目的:
- 调查牙周炎 (急性和慢性) 和不良妊娠结果 (APO) 之间的因果关系.
- 研究的APOs包括低出生体重 (LBW),早产 (PTB),死产,流产和妊娠高血压 (GH).
- 该研究还研究了反向关系:APO影响牙周炎.
主要方法:
- 门德尔随机化 (MR) 研究设计,利用牙周炎的遗传变异.
- 数据来源于欧洲血统的基因组广泛关联研究 (GWAS) 数据库.
- 主要分析采用逆变量加权 (IVW) 方法,使用MR-Egger进行灵敏度分析.
主要成果:
- 牙周炎对PTB,死胎,流产或GH没有显著的因果作用,IVW或MR-Egger没有检测到.
- 使用IVW观察到慢性牙周炎和LBW之间的统计学意义上的关联 (OR1.410,P=0.028) .
- 敏感性分析表明,由于其他方法的结果不显著,在解释慢性牙周炎与LBW联系时要谨慎.
结论:
- 该研究的结果没有确定牙周炎对大多数APO的因果影响,包括LBW,PTB,死产,流产和GH.
- 慢性牙周炎和LBW之间观察到的关联需要进一步调查.
- 由于MR方法的局限性,需要仔细解释结果.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
