This study aimed to evaluate the prevalence and factors associated with dental fluorosis in permanent incisors among children aged 8-10 years in Bangkok, Thailand. We studied 707 children selected by stratified randomization and examined each of them to determine their Dean’s fluorosis index. Parents of the studied children were asked to fill out a questionnaire. The study was conducted from July to October 2014. Chi-square test and multiple logistic regression analysis were used to study the association between various factors and fluorosis among study subjects. Dental fluorosis was found in 18.4% of subjects. Sixteen point one percent and 2.3% of 707 subjects had very mild fluorosis and mild fluorosis, respectively. Factors significantly associated with dental fluorosis were family income (aOR=1.77; 95% CI: 1.10-2.86, p=0.02) and history of taking fluoride supplements (aOR=1.66; 95% CI: 1.07-2.61, p=0.03). This study indicated that the prevalence of fluorosis had increased in Bangkok, but the majority was very mild level.
本研究旨在评估泰国曼谷8至10岁儿童恒牙中氟斑牙的患病率及其相关因素。我们通过分层随机抽样选取了707名儿童，并对他们每个人进行检查以确定其迪恩氟斑牙指数。研究对象的父母被要求填写一份问卷。该研究于2014年7月至10月进行。采用卡方检验和多元逻辑回归分析来研究各因素与研究对象氟斑牙之间的关联。18.4%的研究对象患有氟斑牙。在707名研究对象中，分别有16.1%和2.3%患有非常轻度氟斑牙和轻度氟斑牙。与氟斑牙显著相关的因素是家庭收入（调整后比值比=1.77；95%置信区间：1.10 - 2.86，p = 0.02）和服用氟补充剂的历史（调整后比值比=1.66；95%置信区间：1.07 - 2.61，p = 0.03）。本研究表明，曼谷氟斑牙的患病率有所上升，但大多数处于非常轻度水平。
