To investigate the relationship between chewing sugar-free gum (SFG) and dental caries status in China.
A total of 860 teenagers (aged 12 to 15 years) and 490 adults (aged ≥ 18 years) were recruited using a multistage stratified cluster method from economically developed areas (Beijing, Guangdong) and less economically developed areas (Hubei, Xinjiang). Each participant completed a questionnaire including oral health-related knowledge of SFG and chewing habits of SFG and agreed to undertake a clinical assessment. Potential factors associated with chewing conditions were analysed through a chi-square statistical test. A negative binominal regression analysis was performed to quantify the relationship between dental caries and consumption of SFG.
The overall percentage of the survey population who consumed SFG was 43.4%, and SFG-related knowledge and awareness was only 19.4%. For decayed, missing and filled permanent teeth (DMFT), the mean value was 1.63 ± 2.41 and 2.29 ± 3.65 in the chewing group and non-chewing group, respectively. According to the negative binominal regression analysis, the caries status in the SFG chewing group was better than in the non-chewing group (adjusted prevalence rate ratio [PRR] 0.73; 95% confidence interval [CI] 0.62-0.87).
The chewing condition and oral health-related knowledge and awareness of SFG is low. Chewing SFG is related to a better dental caries status, so regular consumption of SFG should be recommended when promoting oral health.
探讨在中国咀嚼无糖口香糖（SFG）与龋齿状况之间的关系。
采用多阶段分层整群抽样方法，从经济发达地区（北京、广东）和经济欠发达地区（湖北、新疆）招募了860名青少年（12至15岁）和490名成年人（≥18岁）。每位参与者完成一份问卷，内容包括与SFG相关的口腔健康知识和SFG的咀嚼习惯，并同意接受临床评估。通过卡方统计检验分析与咀嚼情况相关的潜在因素。进行负二项回归分析以量化龋齿与SFG消费之间的关系。
食用SFG的调查人群总体比例为43.4%，而与SFG相关的知识和意识仅为19.4%。对于恒牙龋失补牙数（DMFT），咀嚼组和非咀嚼组的平均值分别为1.63±2.41和2.29±3.65。根据负二项回归分析，SFG咀嚼组的龋齿状况优于非咀嚼组（调整患病率比[PRR]为0.73；95%置信区间[CI]为0.62 - 0.87）。
SFG的咀嚼情况以及与口腔健康相关的知识和意识较低。咀嚼SFG与较好的龋齿状况相关，因此在促进口腔健康时应建议定期食用SFG。
