The purpose of this study was to gather base-line data of mottling in 15-year-old children. The survey was carried out in low-fluoride Barnsley Area (F = 0.1 parts/10(6)) in December, 1976. In a random convenience sample, 270 children were examined. The mouth prevalence of mottling was 36.3% and the tooth prevalence was 8.8%. There was no sex difference in the prevalence of mottling. Over 83% of mottling was white (types A and B). Mottling occurred most frequently in the maxillary incisors and was most common in the incisal third of all incisors examined. The results are compared with data from six other studies where the same classification of mottling was used.
本研究的目的是收集15岁儿童氟斑牙的基线数据。该调查于1976年12月在低氟的巴恩斯利地区（氟含量 = 0.1 ppm）进行。在一个随机便利样本中，检查了270名儿童。氟斑牙的口腔患病率为36.3%，牙齿患病率为8.8%。氟斑牙患病率不存在性别差异。超过83%的氟斑牙为白色（A类和B类）。氟斑牙最常发生在上颌切牙，在所检查的所有切牙的切缘三分之一处最为常见。将结果与其他六项使用相同氟斑牙分类的研究数据进行了比较。
