To compare (a) enamel carious (EC) and dentin carious (DC) lesions and (b) caries risk, between normal-weight (NW) and overweight/obese (OW) children/adolescents.
In this cross-sectional study, 91 participants aged 6-12 years were classified according to the body mass index (BMI): NW (n = 50) and OW (n = 41). Caries experience was evaluated using the International Caries Detection and Assessment System (ICDAS) with two thresholds: "EC/DC" (ICDAS 1-3/4-6) and "DC" (ICDAS 4-6). Caries risk was determined by the Caries Management by Risk Assessment (CAMBRA) system. A logistic regression analysis was performed to determine the association among OW, caries thresholds, and caries risk.
Caries experience was similar for both groups at the "EC/DC" threshold (P = .477) and higher for the NW group at the "DC" threshold (P = .009). For CAMBRA, caries risk classification was similar for both groups (P = .082). The logistic regression showed the OW group was less likely to exhibit radiographically visible proximal carious lesions (odds ratio [OR] of 0.330, P = .019), thick biofilm visible on the tooth surface (OR = 0.360, P = .019), high caries risk (OR = 0.367, P = .039), and moderate-to-high caries levels (OR = 0.190, P = .022).
OW children/adolescents had lower caries experience, at both ICDAS thresholds, and lower caries risk, compared to NW children/adolescents.
比较（a）正常体重（NW）和超重/肥胖（OW）儿童/青少年的釉质龋（EC）和牙本质龋（DC）病变，以及（b）龋齿风险。
在这项横断面研究中，根据体重指数（BMI）将 91 名 6-12 岁的参与者分为以下两组：NW（n=50）和 OW（n=41）。使用国际龋病检测和评估系统（ICDAS）评估龋病发生情况，采用两个阈值：“EC/DC”（ICDAS 1-3/4-6）和“DC”（ICDAS 4-6）。采用龋病管理风险评估（CAMBRA）系统评估龋病风险。采用逻辑回归分析确定 OW、龋病阈值和龋病风险之间的关系。
在“EC/DC”阈值下，两组的龋病发生情况相似（P=0.477），而 NW 组在“DC”阈值下更高（P=0.009）。对于 CAMBRA，两组的龋病风险分类相似（P=0.082）。逻辑回归显示，OW 组发生放射状可见近中龋病的可能性较小（比值比 [OR]为 0.330，P=0.019），牙面可见厚生物膜的可能性较小（OR 为 0.360，P=0.019），龋病风险较高（OR 为 0.367，P=0.039），以及中高度龋病水平（OR 为 0.190，P=0.022）。
与 NW 儿童/青少年相比，OW 儿童/青少年在两个 ICDAS 阈值下的龋病发生情况较低，龋病风险也较低。
