To investigate factors associated with the development of root caries in dentition without root caries experience and interactive relationships between risk factors.
We conducted surveys, consisting of an oral examination (oral hygiene, assessment of the number of teeth, coronal and root caries) and a self-reported questionnaire, among employees of a company in Tokyo, Japan in 2016 and 2018. Questionnaires collected data on smoking status, oral hygiene habits, sugar intake, and frequency of dental visits. Multiple logistic regression and decision tree analyses were used to determine factors associated with the development of root caries.
A total of 299 participants aged 25-63 years were included in the analysis. Males, older adults, smokers/past smokers had a significantly greater risk of developing root caries. The risk of developing root caries was significantly associated with the number of teeth with gingival recession at baseline (6-9 teeth, odds ratio [OR]: 7.69, 95 % confidence interval [CI]: 2.31-25.56; 10+ teeth, OR: 9.19, 95 % CI: 2.73-30.95, relative to ≤5 teeth); and with the number of coronal decayed and filled (DF) teeth (11-13 teeth, OR: 3.21, 95 % CI: 1.12-9.24; and ≥14 teeth, OR: 3.60, 95 % CI: 1.27-10.20, relative to ≤10 teeth). Other factors associated with root caries development differed according to the number of teeth with gingival recession and included drinking sugar-sweetened beverages, and the amount of toothpaste used.
Gingival recession and number of coronal DF teeth were associated with the development of root caries.
Multiple factors are associated with root caries development. The effect of risk factors such as drinking sweetened beverages and less toothpaste use is greater in individuals with greater gingival recession and more coronal decayed and filled teeth. Dental practitioners should focus on modifiable risk factors to prevent root caries.
调查无根龋史的牙列中根龋发生的相关因素及危险因素之间的相互关系。
我们于 2016 年和 2018 年在日本东京的一家公司对员工进行了口腔检查（口腔卫生、牙齿数量、冠龋和根龋评估）和自我报告问卷调查。问卷调查收集了吸烟状况、口腔卫生习惯、糖摄入量和就诊频率等数据。采用多因素逻辑回归和决策树分析确定与根龋发生相关的因素。
共纳入 299 名 25-63 岁的参与者。男性、年龄较大者、吸烟者/曾经吸烟者患根龋的风险显著增加。根龋发生的风险与基线时牙龈退缩的牙齿数量显著相关（6-9 颗牙，比值比 [OR]：7.69，95%置信区间 [CI]：2.31-25.56；10 颗以上牙，OR：9.19，95%CI：2.73-30.95，与≤5 颗牙相比）；与冠部龋齿和填充（DF）牙齿的数量也显著相关（11-13 颗牙，OR：3.21，95%CI：1.12-9.24；≥14 颗牙，OR：3.60，95%CI：1.27-10.20，与≤10 颗牙相比）。与根龋发生相关的其他因素也因牙龈退缩牙齿数量而异，包括饮用含糖饮料和牙膏使用量。
牙龈退缩和冠部 DF 牙齿数量与根龋的发生有关。
多种因素与根龋的发生有关。在牙龈退缩程度较大和冠部龋齿和填充牙齿较多的患者中，饮用含糖饮料和使用较少牙膏等危险因素的影响更大。牙科医生应关注可改变的危险因素，以预防根龋。
