Abstract

The caries inhibitory effect of optimally fluoridated drinking water is well documented. Communities are often exposed to naturally fluoridated water with F content exceeding the optimal level. The purpose of this study was to determine the relationship between enamel fluoride, degree of fluorosis (DEGF) and caries incidence (DMFT) in an endemic fluoride area. Eighty-five 14- to 16-year-old children (37 males and 48 females) who were born and had been living continually in the town of Kenhardt in South Africa were selected for this study. The fluoride content of the common water supply is 3.2 ppm F. The DMFT and DEGF were determined clinically. Acid etch biopsies were carried out on both maxillary central incisors of each subject. Ca and F analysis were carried out and mass enamel expressed in microgram and mass F in pg. Data transformations to loge mass F (1nF), loge mass En (1nEn) and square root DMFT were made. The 1nF values were corrected to a standardized depth of 10 micrometer (208.6 microgram enamel equivalent mass) by covariance analysis. Correlations between the parameters square root DMFT, 1nF ad DEGF were calculated, adjusting for the sex of the individual. The correlations were as follows: (formula: see text). A positive association among the three parameters was established.

摘要

最佳氟化饮用水的防龋效果已有充分记录。社区常常接触到氟含量超过最佳水平的天然含氟水。本研究的目的是确定地方性氟病区牙釉质氟、氟斑牙程度（DEGF）与龋病发病率（DMFT）之间的关系。本研究选取了85名14至16岁的儿童（37名男性和48名女性），他们出生并一直生活在南非肯哈特镇。公共供水的氟含量为3.2 ppm F。通过临床检查确定DMFT和DEGF。对每位受试者的上颌中切牙进行酸蚀活检。进行钙和氟分析，牙釉质质量以微克表示，氟质量以皮克表示。对数据进行对数转换，得到对数氟质量（1nF）、对数牙釉质质量（1nEn）和DMFT的平方根。通过协方差分析将1nF值校正到标准化深度10微米（208.6微克牙釉质当量质量）。计算平方根DMFT、1nF和DEGF参数之间的相关性，并根据个体性别进行调整。相关性如下：（公式：见原文）。确定了这三个参数之间存在正相关关系。
