The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure.
The study included 29 orthodontic patients (mean age, 18.2 ± 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (<15,000 rpm; 10 seconds) on the mandibular anterior teeth. Blood samples were collected by inserting a cannula into the left antecubital fossa. A baseline sample was taken before treatment, and a second sample was taken after the stripping procedure. These samples were inoculated into aerobic and anaerobic blood culture bottles and incubated, and the bacterial cultures were identified; the samples collected before and after the stripping procedure were statistically analyzed.
Transient bacteremia was not detected in any pretreatment blood sample, but it was found in 1 postoperative blood sample; this sample tested positive for Streptococcussanguis.
The bacterial species in the positive postoperative blood sample was S sanguis, which might be associated with infective endocarditis. Clinicians should explain the level of risk to the patient and consult a concerned medical specialist.
本研究旨在评估正畸去釉操作相关菌血症的发生率。
研究纳入了 29 名正畸患者(平均年龄 18.2±3.4 岁)。我们采用标准化的去釉操作流程:使用带有角形机头的带孔去釉片,在低速(<15000rpm;10 秒)下处理下颌前牙。通过在前臂肘窝插入导管采集血样。在治疗前采集基线样本,在去釉操作后采集第二份样本。将这些样本接种到需氧和厌氧血培养瓶中进行孵育,并对细菌培养物进行鉴定;对去釉操作前后采集的样本进行统计学分析。
在任何预处理血样中均未检测到一过性菌血症,但在 1 份术后血样中发现了菌血症;该样本对 Sanguissanguis 呈阳性。
阳性术后血样中的细菌种类为 Sanguissanguis,可能与感染性心内膜炎有关。临床医生应向患者解释风险程度,并咨询相关医学专家。
