This paper uses baseline data from a randomized clinical trial to evaluate cross-sectional indicators of root caries in caries-active adults.
Adults (21-80 years) having at least 12 erupted teeth and between one and ten caries lesions were enrolled. Participants (n = 437) received caries exams by trained, calibrated examiners and responded to baseline demographic and medical-dental questionnaires. We examined associations between baseline characteristics and (1) the presence of any root caries using Mantel-Haenszel hypothesis tests and odds ratio (OR) estimators and (2) the number of root surfaces with caries among study participants with exposed root surfaces (n = 349) using Mantel-Haenszel mean score tests and Mann-Whitney estimators.
RESULTS/CONCLUSIONS: Adjusting for study site and age, male gender [OR, 1.72; 95% confidence interval (CI), 1.08, 2.78], white race (OR, 2.39; 95% CI, 1.43, 3.98), recent dental visit (OR, 1.98; 95% CI, 1.07, 3.66), poor self-described oral health (OR, 2.65; 95% CI, 1.10, 6.39), and recent professional fluoride treatment (OR, 1.85; 95% CI, 1.06, 3.25) were significantly associated with increased odds to have any root caries, and study participants with exposed root surfaces characterized by male gender [Mann-Whitney probability estimate (MW) = 0.57; 95% CI, 0.51, 0.63), white race (MW, 0.61; 0.55, 0.68), recent dental visit (MW, 0.58; 0.50, 0.67), poor self-described oral health (MW, 0.61; 0.53, 0.69), and flossing at least once per day (MW, 0.57; 95% CI, 0.51, 0.62) were significantly more likely to have a greater number of root surfaces with caries than a randomly selected study participant from their respective complementary subgroups (female gender, non-white, etc.).
Our findings may help identify individuals at higher root caries risk.
本研究使用一项随机临床试验的基线数据，评估活跃性龋成年人的根龋横断面指标。
纳入至少有 12 颗萌出牙且有 1 至 10 个龋损的 21-80 岁成年人。参与者（n=437）接受了经过培训和校准的检查者的龋病检查，并对基线人口统计学和医学-牙科问卷进行了回复。我们使用 Mantel-Haenszel 假设检验和比值比（OR）估计值，检查了基线特征与（1）任何根龋的存在之间的关联，以及（2）暴露根面的研究参与者中根面龋的数量之间的关联（n=349），使用 Mantel-Haenszel 平均得分检验和 Mann-Whitney 估计值。
结果/结论：在调整研究地点和年龄后，男性（OR，1.72；95%置信区间（CI），1.08，2.78）、白种人（OR，2.39；95%CI，1.43，3.98）、最近看牙（OR，1.98；95%CI，1.07，3.66）、自述口腔健康状况不佳（OR，2.65；95%CI，1.10，6.39）和最近接受专业氟化物治疗（OR，1.85；95%CI，1.06，3.25）与增加发生任何根龋的几率显著相关，且具有暴露根面特征的研究参与者为男性（Mann-Whitney 概率估计值（MW）=0.57；95%CI，0.51，0.63）、白种人（MW，0.61；95%CI，0.55，0.68）、最近看牙（MW，0.58；95%CI，0.50，0.67）、自述口腔健康状况不佳（MW，0.61；95%CI，0.53，0.69）和每天至少用牙线洁牙一次（MW，0.57；95%CI，0.51，0.62），与各自互补亚组中随机选择的研究参与者相比，他们更有可能有更多的根面发生龋病。
我们的研究结果可能有助于识别更高根龋风险的个体。
