This study investigated root caries related findings made in connection with basic clinical dental routines. A total of 410 adults, mean age 42.8 years, seeking dental care in two Slovenian communities, rural Ravne and urban Ljubljana, during a three-month period, were clinically examined for root caries. Primary root caries was defined as a softened yellowish-brown lesion gently penetrable by an explorer and situated principally on a root surface. Past root caries was defined as fillings at a similar location. A subject's oral hygiene was judged clinically as good, fair or poor, based on presence of dental plaque and subgingival calculus. Subjects' background variables included age, gender, and number of teeth. Subjects had on average 23.1 teeth, from which 0.8 teeth had primary root caries and 0.4 had fillings on root surfaces. Primary root caries occurred in 42 per cent of subjects, in 38 per cent of men and 45 per cent of women (P = 0.21), but fillings on root surfaces in only 19 per cent of the subjects, 11 per cent of men and 25 per cent of women (P = 0.001). The strongest factors explaining the presence of root caries, with control for other factors, were poor oral hygiene (odds ratio 3.1), smaller number of teeth (odds ratio 2.3 to 2.7), and older age (odds ratio 2.1). In conclusion, in everyday clinical dental practice, more emphasis should be placed on patients' proper oral hygiene and their encouragement and motivation to achieve it.
本研究调查了与基本牙科临床诊疗程序相关的根龋相关发现。在三个月的时间里，对斯洛文尼亚两个社区（农村的拉夫内和城市的卢布尔雅那）寻求牙科治疗的410名成年人（平均年龄42.8岁）进行了根龋临床检查。原发性根龋被定义为用探针可轻轻探入的软化黄褐色病变，主要位于牙根表面。既往根龋被定义为在类似位置的充填物。根据牙菌斑和龈下牙石的存在情况，临床判断受试者的口腔卫生状况为良好、一般或较差。受试者的背景变量包括年龄、性别和牙齿数量。受试者平均有23.1颗牙齿，其中0.8颗有原发性根龋，0.4颗有牙根表面充填物。42%的受试者发生原发性根龋，男性为38%，女性为45%（P = 0.21），但只有19%的受试者有牙根表面充填物，男性为11%，女性为25%（P = 0.001）。在控制其他因素的情况下，解释根龋存在的最强因素是口腔卫生差（比值比3.1）、牙齿数量较少（比值比2.3至2.7）和年龄较大（比值比2.1）。总之，在日常牙科临床实践中，应更加重视患者保持适当的口腔卫生，并鼓励和激发他们做到这一点。
