概括

在牙斑中发现的寄生虫Entamoeba gingivalis在患有牙周病的个体中更为普遍. 糟糕的口腔卫生,比如不用牙线,会增加感染的风险.

科学领域:

口腔微生物学口腔微生物学
寄生虫学的寄生虫学
牙周病学牙周病学

背景情况:

牙周虫 (Entamoeba gingivalis) 是一种在人类口腔中发现的原生虫寄生虫.
它与牙周疾病的关联需要进一步调查.

研究的目的:

为了确定牙斑中Entamoeba gingivalis ST1和ST2-Kamaktli亚型的患病率.
评估Entamoeba gingivalis感染与牙周状况之间的关联.

主要方法:

一项涉及159名参与者的病例控制研究 (牙周炎,牙周炎,健康).
使用嵌套PCR和DNA测序分析的牙斑样本.
风险因素通过问卷进行评估.

主要成果:

总体上,Entamoeba gingivalis的患病率为17.6%,在牙周炎患者 (28.3%) 中显著高于健康对照组 (7.5%).
ST1是主要的亚型 (75%),其次是ST2-Kamaktli (25%).
较低的教育程度和缺乏牙线使用是显著的危险因素.

结论:

牙周病中更为普遍的Entamoeba gingivalis,这表明它可能在口腔病理学中发挥作用.
识别和解决诸如口腔卫生不良等风险因素对于预防和治疗至关重要.

关键词:

牙炎是一种炎症.嵌套的PCR可以使用.牙周炎是指牙周炎的一种疾病.患病率的流行情况.

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
