Infective endocarditis (IE) is a serious disease that affects the surface of the endocardium. The spread of microorganisms from the oral cavity has been associated with the occurrence of IE.
To analyze whether dental treatment before cardiac valve surgery (CVS) influenced the occurrence of IE.
We performed a retrospective analysis of the medical and dental histories of patients undergoing CVS from 2004 to 2014. The sample consisted of 481 patients who underwent CVS divided into two groups: patients submitted to dental treatment prior to CVS (n = 110) and patients undergoing CVS without dental treatment (n = 371).
Of the total sample, 38 patients (8%) were diagnosed with IE. No significant difference was detected (p = 0.496) in comparing the occurrence of IE in the group with dental preparation (6.4%) and without dental preparation (8.4%). The logistic regression model confirmed that dental treatment did not change the IE risk (p = 0.504) and indicated that age (p < 0.003) and gender (p = 0.013) were significant risk factors for IE. There was a high demand for dental procedures in the group receiving dental preparation, with no significant differences between the patients with or without IE. Hemoculture indicated qualitative differences in comparing patients with and without dental treatment, especially in the frequency of and .
The results did not allow for the determination of the impact of dental treatment before CVS on IE outcomes. However, it was not possible to exclude the potential beneficial effects of dental treatment in the prevention of IE.
感染性心内膜炎（IE）是一种影响心内膜表面的严重疾病。口腔微生物的传播与IE的发生有关。
分析心脏瓣膜手术（CVS）前的牙科治疗是否会影响IE的发生。
我们对2004年至2014年接受CVS治疗的患者的医疗和牙科病史进行了回顾性分析。样本包括481例接受CVS治疗的患者，分为两组：CVS治疗前接受牙科治疗的患者（n = 110）和未接受牙科治疗的CVS患者（n = 371）。
在总样本中，38例患者（8%）被诊断为IE。比较进行牙科准备的组（6.4%）和未进行牙科准备的组（8.4%）中IE的发生率，未发现显著差异（p = 0.496）。逻辑回归模型证实牙科治疗不会改变IE风险（p = 0.504），并表明年龄（p < 0.003）和性别（p = 0.013）是IE的显著风险因素。接受牙科准备的组对牙科手术的需求很高，有IE和无IE的患者之间没有显著差异。血培养表明，比较接受和未接受牙科治疗的患者存在质量差异，尤其是在 和 的频率方面。
结果无法确定CVS前的牙科治疗对IE结局的影响。然而，无法排除牙科治疗在预防IE方面的潜在有益作用。
