To examine the relationship between the presence of enamel defects, dental caries in primary teeth, and exposure to various fluoride technologies and the presence of dental caries in permanent teeth in children with mixed dentition.
A cross-sectional study was conducted in 713 children aged 6-9 years old in 4 elementary schools in Campeche, Mexico through the use of a questionnaire for the mothers and an oral examination in the children. The dependent variable was the prevalence of caries in permanent dentition.
The mean number of decay, missing or filling teeth in primary dentition (dmft) and in permanent dentition (DMFT) was 2.48 (2.82) (deft > 0 = 58.9%) and 0.40 (0.98) (DMFT > 0 = 18.2%), respectively. The significant caries index (SiC), which is calculated in deciduous dentition, was 5.85 for 6 year-olds. Multivariate logistic regression adjusted for variables related to fluoride exposure revealed that older age (OR = 2.99), a deft of > 0 (OR = 5.46), and lower maternal educational level (OR = 1.57) were significantly associated with a higher number of dental caries in permanent teeth. An interaction between sex and enamel defects was also found.
The number of dental caries in both primary and permanent dentitions was relatively smaller than that found in prior studies performed in Mexican populations. The results confirm that the presence of caries in primary dentition is strongly associated with caries in permanent dentition. No significant relationship was found between fluoride exposure and dental caries in permanent dentition.
研究混合牙列期儿童牙釉质缺陷、乳牙龋齿与接触不同氟化物技术之间的关系，以及恒牙龋齿的患病情况。
在墨西哥坎佩切州的4所小学对713名6至9岁儿童进行了一项横断面研究，通过向母亲发放问卷以及对儿童进行口腔检查来收集数据。因变量为恒牙列龋齿的患病率。
乳牙列（dmft）和恒牙列（DMFT）中龋失补牙的平均数量分别为2.48（2.82）（乳牙有龋 = 58.9%）和0.40（0.98）（恒牙有龋 = 18.2%）。6岁儿童乳牙列的显著龋指数（SiC）为5.85。经对与氟暴露相关的变量进行调整后的多因素逻辑回归分析显示，年龄较大（比值比[OR]=2.99）、乳牙有龋（OR = 5.46）以及母亲教育水平较低（OR = 1.57）与恒牙龋齿数量较多显著相关。此外，还发现了性别与牙釉质缺陷之间的交互作用。
与之前针对墨西哥人群的研究相比，本研究中乳牙列和恒牙列的龋齿数量相对较少。结果证实，乳牙龋齿的存在与恒牙龋齿密切相关。未发现氟暴露与恒牙龋齿之间存在显著关系。
