Abstract：
Despite the increase in the root caries prevalence, little is still known about how dentists manage this condition. The present study aimed to evaluate the knowledge of dentists on diagnosing and recording root caries lesions (RCL).
The survey consisted of three domains: (1) dentists\' knowledge on diagnosing, recording and managing RCL; (2) information about their current general clinical routines; and (3) their demographics. The four Swiss Universities distributed the survey via e-mail lists for alumni or professionals participating in continuing education. The data was quality checked. Construct validity, internal reliability and intraclass correlation (ICC) were assessed.
The survey was answered by 383 dentists from 25(out of 26) cantons [mean(SD) working experience: 22.5(12) years]. The majority replied that they see less than 5 patients with RCL per week, whereas 41 have at least 5 per week, and 40 % (157 dentists) do not distinguish RCL from coronal caries in their patients\' medical records. When diagnosing active RCL, tactile sensation was the most predominant criterion (n = 380), whereas color (n = 224) and visual appearance (n = 129) of the lesion were less often selected. The most often chosen risk factors for RCL were poor oral hygiene and presence of biofilm.The responses were significantly influenced by the participants\' place of education, their age and working area.
The present survey highlights the huge diversity in diagnosing, recording and assessing risk factors of RCL. The benefits of an appropriate diagnosis, recording and management of risk factors of RCL should be highlighted in under- and postgraduate dental education.
A great diversity in diagnosing, recording and assessing risk factors of RCL was observed, which migh strongly impact how dentists manage RCL. The study emphasizes the necessity for intensive efforts to bridge the gap between guideline recommendations and their implementation in private dental practices.

摘要：
目标：尽管根龋患病率增加，人们对牙医如何管理这种情况知之甚少。本研究旨在评估牙医在诊断和记录根龋病变（RCL）方面的知识。
方法：调查包括三个领域：（1）牙医诊断知识，记录和管理RCL;(2)关于他们当前的一般临床常规的信息;和(3)他们的人口统计学。.四所瑞士大学通过电子邮件列表为参加继续教育的校友或专业人士分发了调查。对数据进行质量检查。构造效度，评估了内部可靠性和组内相关性(ICC).
结果：来自25个（26个）州的383名牙医回答了该调查[平均（SD）工作经验：22.5（12）年]。大多数人回答说，他们每周看到不到5名RCL患者，而41人每周至少有5人，40％（157名牙医）在其患者的医疗记录中没有区分RCL和冠状龋齿。诊断活动RCL时,触觉是最主要的标准(n=380)，而病变的颜色（n=224）和视觉外观（n=129）的选择较少。最常选择的RCL风险因素是口腔卫生差和生物膜的存在。回答受到参与者受教育地点的显著影响，他们的年龄和工作区域。
结论：本调查突出了诊断的巨大多样性，记录和评估RCL的危险因素。适当诊断的好处，RCL危险因素的记录和管理应突出在下和研究生牙科教育中。
结论：诊断的多样性很大，记录和评估RXL的危险因素，这极大地影响了牙医如何管理RCL。该研究强调必须加紧努力，以弥合指南建议与其在私人牙科实践中的实施之间的差距。
