To assess the prevalence and severity of dental fluorosis in children aged 7 to 12.
The study population comprised 266 children aged 7 to 12 years, enrolled in a public school in the city of Rio de Janeiro, Brazil, selected using a simple random sample method. All examinations were carried out between August and December 1999 by a single trained and calibrated examiner (Kappa = 0.92). After obtaining their parents' consent the children had their upper permanent incisors examined under natural light. Their teeth were previously cleaned and dried with cotton rolls. The differential diagnosis between milder forms of dental fluorosis and nonfluoride enamel opacities was made according to Russel's diagnostic criteria. The severity of fluorosis was assessed by the Thylstrup and Fejerskov Index (TF).
The prevalence of dental fluorosis was 7.9% (CI 95%, 5.0-11.8). The severity ranged from 1 to 3 and 77% of the affected teeth had a TF score of 1.
These results suggest that dental fluorosis does not represent a public health problem in this population.
评估7至12岁儿童氟斑牙的患病率及严重程度。
研究对象包括266名7至12岁的儿童，他们就读于巴西里约热内卢市的一所公立学校，采用简单随机抽样方法选取。所有检查均在1999年8月至12月期间由一名经过培训且校准合格的检查者进行（卡帕值=0.92）。在获得家长同意后，让孩子们在自然光下检查其上颌恒切牙。检查前先用棉卷清洁并擦干牙齿。根据拉塞尔诊断标准对较轻形式的氟斑牙与非氟化物釉质浑浊进行鉴别诊断。氟斑牙的严重程度通过蒂尔斯楚普和费耶斯科夫指数（TF）进行评估。
氟斑牙的患病率为7.9%（95%置信区间，5.0 - 11.8）。严重程度范围为1至3级，77%的患牙TF评分为1。
这些结果表明，氟斑牙在该人群中不构成公共卫生问题。
