背景:儿童早期龋齿(ECC)在全球范围内仍然是一个严重的口腔健康问题。在世界某些地区实施的基于风险的龋齿管理(RBCM)已有效地预防了ECC。然而,缺乏对RBCM在中国儿童中应用的前瞻性研究,对它的有效性知之甚少。本研究的目的是评估RBCM在万州区3-5岁儿童龋齿预防中的有效性。重庆市,中国。
方法:随机抽取万州4所幼儿园3~5岁儿童进行基线牙科检查和龋齿风险评估(CRA),并根据幼儿园情况随机分为实验组(EG)或对照组(CG)。EG根据儿童的龋齿风险水平采取不同强度的龋齿预防措施。根据标准预防,CG每年接受两次全口氟化物,不管他们患龋齿的风险。一年后,进行了另一项牙科检查和CRA,为了观察腐烂的变化,失踪,和填充牙齿(dmft)指数和龋齿风险,并分析可能影响新发龋发生率的潜在因素。
结果:收集了291名儿童的完整数据(EG,N=140,84.8%;CG,N=181,83.4%)。共有25.7%的EG和50.3%的CG儿童出现了新的龋齿,新增dmft评分分别为0.54±1.12和1.32±1.72(P<0.05)。多因素Logistic回归表明,生活在农村地区的儿童,分配给CG,在基线时被评为高风险的患者更有可能发生新的龋齿(P<0.05)。EG患儿患龋风险增加的比例明显低于CG患儿(P<0.05)。
结论:RBCM可有效预防3-5岁万州儿童的新龋,降低患龋风险增加的儿童比例。这是一种有效的预防ECC的方法。
背景:该试验已在中国临床试验注册。注册号为ChiCTR230067551(2023年1月11日)。
BACKGROUND: Early childhood caries (ECC) remain a serious oral health problem on a global scale. Risk-based caries management (RBCM) implemented in some parts of the world has been effective in preventing ECC. However, there is a lack of prospective research on the application of RBCM among Chinese children, and little is known about its effectiveness. The purpose of this
study was to evaluate the effectiveness of RBCM in preventing caries among children aged 3-5 years in Wanzhou District, Chongqing Municipality, China.
METHODS: Three- to five-year-old children from four kindergartens in Wanzhou were randomly selected for baseline dental examination and caries risk assessment (CRA) and randomly assigned to the experimental group (EG) or the control group (CG) according to the kindergarten. The EG received caries prevention measures of different intensities based on the child\'s caries risk level. The CG received full-mouth fluoride twice a year according to standard prevention, regardless of their caries risk. One year later, another dental examination and CRA were conducted, to observe changes in the decayed, missing, and filled teeth (dmft) index and caries risk, and to analyze potential factors that may affect the incidence of new caries.
RESULTS: Complete data were collected from 291 children (EG, N = 140, 84.8%; CG, N = 181, 83.4%). A total of 25.7% of the EG and 50.3% of the CG children developed new caries, with newly added dmft scores of 0.54 ± 1.12 and 1.32 ± 1.72, respectively (P < 0.05). Multivariate logistic regression indicated that children living in rural areas, assigned to the CG, and rated as high-risk at baseline were more likely to develop new caries (P < 0.05). The proportion of children with an increased caries risk in the EG was significantly lower than that in the CG (P < 0.05).
CONCLUSIONS: RBCM effectively prevented new caries in 3- to 5-year-old Wanzhou children and reduced the proportion of children at increased risk of caries. It is an effective approach for preventing ECC.
BACKGROUND: This
trial was registered in the Chinese Clinical Trials Register. The registration number was ChiCTR230067551 (11/01/2023).
