This connection centers around an oral infection called periodontitis.

这种联系围绕着一种叫炎的口腔感染。

In a 2012 study, it was found that 53% of the patients with erectile dysfunction also had severe periodontitis.

在 2012 年的一项研究中发现，53% 的勃起功能障碍患者还患有严重的炎。

And after that, you not brushing your teeth would lead to periodontitis.

而之后，你不刷会导致炎。

But while we wait for results, maintaining good oral hygiene to avoid periodontitis seems to be a great way to reduce risk, too.

但在我们等待结果的同时，保持良好的口腔卫生，避免患炎，似乎也是降低风险的一个好方法。

The idea is that, as periodontitis breaks down cells in the gums, P. gingivalis is able to break into the rest of the body.

其理念是，当炎破坏龈细胞时，龈卟啉菌能侵入身体的其他部位。

So periodontitis is pretty common, with the Centers for Disease Control and Prevention in the United States citing that about 50% of people thirty or over have it to some degree.

因此炎相当普遍，美国疾病控制和预防中心指出，30 岁以人群中有 50% 的人在某种程度患有炎。

When bacteria really starts to build up, you increase your risk of developing something called periodontitis, which is the erosion of tissue, gums and bone that support your teeth.

当细菌真正开始滋生时，就会增加患炎的风险，炎是支撑齿的组织、龈和骨骼的侵蚀。

More importantly, RCT eliminates the pulpal innate immuneresponse and natural biological defense against bacterial invasion, leaving the treated pulpless tooth more susceptible to recurrentcaries, apical periodontitis, and ultimate tooth fracture or loss.

更重要的是, RCT消除了髓先天免疫反应和针对细菌入侵的自然生物防御, 使经过治疗的无髓齿更容易复发, 尖端炎和最终的齿骨折或脱落。

Also, some systemic diseases such as diabetes, rheumatoid arthritis, and systemic lupus erythematosis can enhance inflammation in the periodontium which can lead to a shift in bacterial composition and increase the risk or severity of periodontitis.

此外，某些系统性疾病，例如糖尿病、类风湿关节炎、系统性红斑狼疮，会增加组织炎症，从而改变口腔微生物群中细菌的组成，并增患炎的风险或加重炎。
