To investigate the incidence of bacteremia in the bloodstream immediately after orthodontic mini-implant insertion, which can be an invasive procedure.
Blood samples (10 mL) were taken before and after mini-implant insertion from 40 patients (18 males, 22 females; mean age 21.3 ± 7.7 years). These samples were inoculated into BacT/Alert aerobic and anaerobic blood culture bottles and processed in a BacT/Alert 9240 Blood Culture System. The findings were analyzed with the McNemar test.
No bacteremia was detected in the pretreatment samples, but it was in one of the postprocedure samples. The respective bacteria was Streptococcus sanguinis, which is strongly associated with bacterial endocarditis.
Orthodontic mini-implant placement might possibly be correlated to transitory bacteremia. Therefore, a very careful approach seems indicated when dealing with patients who are at risk for cardiopathic complications.
研究正畸微型种植体植入后即刻在血液中发生菌血症的发生率，正畸微型种植体植入是一种侵入性操作。
从40例患者（18例男性，22例女性；平均年龄21.3±7.7岁）身上在微型种植体植入前后采集血样（10 mL）。将这些血样接种到BacT/Alert需氧和厌氧血培养瓶中，并在BacT/Alert 9240血培养系统中进行处理。采用McNemar检验分析结果。
预处理样本中未检测到菌血症，但术后样本中有一份检测到菌血症。分离出的细菌为血链球菌，它与细菌性心内膜炎密切相关。
正畸微型种植体植入可能与短暂性菌血症有关。因此，在处理有心脏并发症风险的患者时，似乎需要采取非常谨慎的方法。
