To investigate whether children with obesity experienced more erosion and caries than children with normal weight.
This study involved children aged 7-15 years. The study and control group comprised 32 children with BMI > 98th centile and 32 healthy children with normal BMI-for-age, respectively. O'Sullivan Erosion Index and WHO Caries Index were used in the examination of erosion and caries, respectively. Stimulated salivary flow rate, buffering capacity, Streptococcus mutans and lactobacilli counts (CFU/ml) were evaluated. A cross-sectional questionnaire survey was employed to collect information on participant's demographic background, oral health history and habits, and utilisation of dental care services.
Children with obesity were more likely to have erosion than healthy children (p < 0.001), and had more erosion in terms of severity (p < 0.0001) and area affected (p < 0.0001), but not in the number of surfaces affected (p = 0.167). Posterior teeth were less likely than anterior teeth to be affected by erosion (OR 0.32, 95 % CI 0.012-0.082). Gender had no effect on erosion. There were no statistically significant differences in the DMFT, saliva profiles or questionnaire responses between the groups.
Children with obesity may have high risk of dental erosion, but do not necessarily have higher risk of dental caries than children with normal weight.
研究肥胖儿童比正常体重儿童是否经历更多的牙釉质侵蚀和龋齿。
本研究纳入7至15岁儿童。研究组和对照组分别包括32名BMI>第98百分位数的儿童和32名年龄别BMI正常的健康儿童。分别使用奥沙利文牙釉质侵蚀指数和世界卫生组织龋齿指数检查牙釉质侵蚀和龋齿情况。评估刺激唾液流速、缓冲能力、变形链球菌和乳酸杆菌计数（CFU/ml）。采用横断面问卷调查收集参与者的人口统计学背景、口腔健康史和习惯以及牙科护理服务利用情况的信息。
肥胖儿童比健康儿童更易发生牙釉质侵蚀（p<0.001），在严重程度（p<0.0001）和受影响面积（p<0.0001）方面有更多的牙釉质侵蚀，但在受影响表面数量方面无差异（p=0.167）。后牙比前牙受牙釉质侵蚀的可能性小（OR 0.32，95%CI 0.012 - 0.082）。性别对牙釉质侵蚀无影响。两组之间的DMFT、唾液指标或问卷调查结果无统计学显著差异。
肥胖儿童可能有较高的牙釉质侵蚀风险，但与正常体重儿童相比，不一定有更高的龋齿风险。
