Tooth brushing with fluoridated toothpaste has become the most important way to provide the anti-caries effect of fluoride around the world. China has promoted the use of fluoridated toothpaste since 1989. However, there are few studies on the national profile of use of fluoridated toothpaste and related factors in Chinese adolescents. We carried out this study to investigate oral hygiene behaviours, especially the status of tooth brushing with fluoridated toothpaste and its correlates among adolescents, based on data from the latest Nation Oral Health Survey in mainland China.
This cross-sectional study recruited 118,601 participants aged 12-15 years using multistage stratified sampling. Questionnaires were completed by students at school. Data employed in analyses were extracted from the questionnaire, including information on tooth brushing, fluoridated toothpaste, dental floss, sociodemographic factors, fluoride knowledge and attitude towards regular dental check-ups. A binary logistic regression was performed to compute the odds ratios (OR). Tooth brushing twice daily with fluoridated toothpaste was the dependent variable. Sociodemographic factors, fluoride knowledge, attitude towards regular dental check-ups, dental visit experience and perceived oral health were the independent variables. P < 0.05 was considered statistically significant.
A total of 32.6% of participants brushed their teeth twice daily, 7.4% used fluoridated toothpaste, and 3.9% cleaned their teeth twice daily with fluoridated toothpaste. The logistic regression showed the probability of twice-a-day tooth brushing with fluoridated toothpaste was higher among these groups: females (OR: 1.141; 95%CI: 1.072-1.214), 15-year-olds (OR: 1.786; 95%CI: 1.634-1.952), from urban areas (OR: 1.389; 95%CI: 1.288-1.497), without siblings (OR: 1.351; 95%CI: 1.259-1.450), with an educated father (OR: 1. 605; 95%CI: 1.442-1.788) and mother (OR: 1.706; 95%CI: 1.530-1.903), having dental visit experiences (OR: 1.702; 95%CI: 1.589-1.823), rating one's oral health as good (OR: 2.341; 95%CI: 2.083-2.631), having fluoride knowledge (OR: 4.345; 95%CI: 4.034-4.678) and having a positive attitude towards regular dental check-ups (OR: 1.589; 95%CI: 1.460-1.729).
The oral hygiene behaviours of Chinese adolescents were undesirable. Twice daily tooth brushing with fluoridated toothpaste was significantly associated with sociodemographic factors, fluoride knowledge, and attitudes towards regular dental check-ups.
用含氟牙膏刷牙已经成为全世界提供氟化物防龋作用的最重要方法。中国自 1989 年以来就一直在推广使用含氟牙膏。然而，关于中国青少年使用含氟牙膏的全国概况和相关因素的研究很少。我们开展了这项研究，基于中国大陆最新的全国口腔健康调查数据，调查了青少年的口腔卫生行为，特别是用含氟牙膏刷牙的情况及其相关因素。
本横断面研究采用多阶段分层抽样方法，招募了 118601 名 12-15 岁的参与者。学生在学校完成问卷。分析中使用的数据是从问卷中提取的，包括信息关于刷牙、含氟牙膏、牙线、社会人口因素、氟化物知识和定期看牙医的态度。使用二项逻辑回归计算优势比（OR）。每日刷牙两次并用含氟牙膏刷牙是因变量。社会人口因素、氟化物知识、定期看牙医的态度、看牙医的经历和自我感觉的口腔健康是自变量。P 值<0.05 被认为具有统计学意义。
共有 32.6%的参与者每天刷牙两次，7.4%的人使用含氟牙膏，3.9%的人每天用含氟牙膏刷牙两次。逻辑回归显示，以下人群每天用含氟牙膏刷牙两次的概率更高：女性（OR：1.141；95%CI：1.072-1.214）、15 岁（OR：1.786；95%CI：1.634-1.952）、城市地区（OR：1.389；95%CI：1.288-1.497）、没有兄弟姐妹（OR：1.351；95%CI：1.259-1.450）、父亲受过教育（OR：1.605；95%CI：1.442-1.788）和母亲（OR：1.706；95%CI：1.530-1.903）、有看牙医的经历（OR：1.702；95%CI：1.589-1.823）、自我感觉口腔健康良好（OR：2.341；95%CI：2.083-2.631）、有氟化物知识（OR：4.345；95%CI：4.034-4.678）和对定期看牙医持积极态度（OR：1.589；95%CI：1.460-1.729）。
中国青少年的口腔卫生行为不理想。每天刷牙两次并用含氟牙膏刷牙与社会人口因素、氟化物知识和定期看牙医的态度显著相关。
