Statement of Problem : Dental procedures leading to oral tissue injuries may provoke bacterial release to the blood stream causing infective endocarditis (IE) in vulnerable patients. The guideline which was proposed by AHA has been updated 9 times having the last update published in 2007. This study was endeavored to uncover the level of knowledge of general dental practitioners in Shiraz, concerning the 2007 AHA guidelines for endocarditis prophylaxis in patients with cardiac problems receiving dental treatments.
This cross- sectional and descriptive analytical study included 150 dentists as participants. All practitioners were given a self -report questionnaire which consisted of three sections. Questions were designed to assess their knowledge of antibiotic prophylaxis in patients with cardiac disease.
Almost all participants (93%) were aware of antibiotic prophylaxis to be essential for tooth extraction. Most participants did not believe in prophylaxis for noninvasive procedures (such as shedding of primary teeth, impression, intraoral radiography). From all of the respondents, 75% considered Amoxicillin to be the antibiotic of choice and 57% were acquainted with the correct dose of Amoxicillin for high risk patients.
The study identified a potential for under/over prescription of antibiotic prophylaxis under the current guideline. Burden of IE necessitates more accurate knowledge of antibiotic prophylaxis in the undergraduate curriculum and continuing education programs of dentistry.
问题陈述：导致口腔组织损伤的牙科手术可能会促使细菌释放到血流中，从而在易感染患者中引发感染性心内膜炎（IE）。美国心脏协会（AHA）提出的指南已更新9次，最新一次更新于2007年发布。本研究旨在揭示设拉子地区普通牙科医生对2007年AHA关于接受牙科治疗的心脏疾病患者心内膜炎预防指南的了解程度。
这项横断面描述性分析研究纳入了150名牙医作为参与者。所有从业者都收到了一份自我报告问卷，该问卷由三个部分组成。问题旨在评估他们对心脏病患者抗生素预防的了解。
几乎所有参与者（93%）都意识到抗生素预防对于拔牙至关重要。大多数参与者不认为非侵入性手术（如乳牙脱落、取模、口腔内放射摄影）需要预防。在所有受访者中，75%认为阿莫西林是首选抗生素，57%了解高危患者阿莫西林的正确剂量。
该研究发现，根据当前指南，抗生素预防存在处方不足/过量的可能性。感染性心内膜炎的负担使得在牙科本科课程和继续教育项目中更准确地了解抗生素预防成为必要。
