Over the last two decades, the prevalence of dental caries in children has decreased and the prevalence of dental fluorosis has increased. Knowledge on the epidemiologic conditions of a population is fundamental for the planning of health programs.
To determine the prevalence of dental caries and dental fluorosis among schoolchildren, in Catalão, Goiás, Brazil.
A random sample of 432 schoolchildren aged 7-12-years old was obtained. WHO (1997) criteria for dental caries and fluorosis diagnosis were used.
The DMFT indexes were 0.97; 1.20; 1.80; 1.62; 2.40 and 2.51 for 7, 8, 9, 10, 11 and 12 years old, respectively. Analysis of dental fluorosis for the same ages presented higher prevalence at 12 years old and for the female gender. The percentage of questionable dental fluorosis (Dean's classification) was 34.0%. Only 3% of the sample presented dental fluorosis with scores very mild, mild and moderate.
The prevalence of caries in schoolchildren of Catalão, Goiás, Brazil, was low. In average, private schools showed better results than public schools; however, all schools presented a low DMFT index. In this study, dental fluorosis is not a public health problem and has not damaged dental esthetics.
在过去的二十年中，儿童龋齿的患病率有所下降，而氟斑牙的患病率有所上升。了解人群的流行病学状况对于规划卫生计划至关重要。
确定巴西戈亚斯州卡塔劳市学龄儿童的龋齿和氟斑牙患病率。
采用随机抽样方法，抽取了 432 名 7-12 岁的在校儿童。采用世界卫生组织（1997 年）的龋齿和氟斑牙诊断标准。
DMFT 指数分别为 7、8、9、10、11 和 12 岁儿童的 0.97、1.20、1.80、1.62、2.40 和 2.51。同样年龄的氟斑牙分析显示，12 岁和女性的患病率更高。可疑氟斑牙（迪恩分类）的百分比为 34.0%。只有 3%的样本出现极轻度、轻度和中度氟斑牙。
巴西戈亚斯州卡塔劳市学龄儿童的龋齿患病率较低。平均而言，私立学校的表现优于公立学校，但所有学校的 DMFT 指数均较低。在本研究中，氟斑牙不是公共卫生问题，也没有损害牙齿美观。
