目的：分析学龄前儿童监护人(简称“家长”)对局部用氟预防口腔龋齿认知度及其影响因素,为制定针对性口腔健康教育策略提供依据。方法：采用多阶段、随机抽样法,以2022年1-12月来我院儿童口腔科就诊的160名学龄前儿童家长为研究对象,对其进行相关问卷调查,采用Logistic回归方程分析影响家长对局部用氟预防口腔龋齿认知度的干预因素。结果：调查对象局部用氟预防口腔龋齿认知度较差,口腔健康知识不系统。问卷评估后,160名家长中有108名≥9分,纳入对照组,有52名＜9分纳入观察组。两组性别、月收入水平、对口腔健康态度、龋齿经历、婚姻状况比较,差异有统计学意义(P＜0.05)。性别、月收入水平、对口腔健康态度、龋齿经历、婚姻状况是影响家长局部用氟预防口腔龋齿认知度的因素。结论：调查地区家长局部用氟预防口腔龋齿认知度较差,主要与性别、月收入水平、对口腔健康态度、龋齿经历、婚姻状况有关,应根据上述影响因素对家长有针对性的开展健康教育,提高家长认知水平,对降低患龋风险及促进儿童养成健康口腔习惯具有积极意义。

Objective: To analyze the awareness of preschool children"s guardians ("parents") about the prevention of oral caries with topical fluoride and its influencing factors, so as to provide a basis for formulating targeted oral health education strategies. Methods: Using a multi-stage, random sampling method, 160 parents of preschool children who came to our dental department for physical examination from January to December 2022 were studied, and a relevant questionnaire was administered to them, and a logistic regression equation was used to analyze the intervention factors affecting parents" awareness of topical fluoride for oral caries prevention. Results: The survey respondents had poor knowledge of topical fluoride for oral caries prevention and unsystematic oral health knowledge. After questionnaire assessment, 108 out of 160 parents with ≥9 points were included in the control group, and 52 with <9 points were included in the observation group. The differences were statistically significant (P < 0.05) when comparing gender, monthly income level, attitude toward oral health, dental caries experience, and marital status between the two groups. Gender, monthly income level, attitude toward oral health, caries experience, and marital status were the factors affecting parents" awareness of topical fluoride for oral caries prevention. Conclusion: Parents" awareness of topical fluoride for oral caries prevention in the survey area is poor, mainly related to gender, monthly income level, attitude towards oral health, caries experience and marital status. Targeted health education should be provided to parents according to the above influencing factors to improve parents" awareness level, which has positive significance to reduce the risk of caries and promote children to develop healthy oral habits.
