This study assesses the effect on enamel formation of the use of fluoride toothpaste in a fluoridated area. The prevalence of enamel hypoplasia in 251 9-10-year-old children born and raised in a fluoridated city (Birmingham) was compared with that in 319 similar children born and raised in a non-fluoridated city (Leeds). Observer bias was eliminated by the use of a new photographic technique, enabling colour slides of both groups to be assessed together in a random order. Scoring was done using both the Jackson-Al-Alousi (J-A) index, which is designed to record nonspecific hypoplasias and the Tooth Surface Index of Fluorosis (TSIF). Both were compared to the results from conventional clinical recording using the J-A index. The results showed that the photographic method was highly reproducible and more sensitive than conventional recording and showed a higher level of mild fluorosis in the fluoridated area. However, no evidence of an increase in the higher grades of fluorosis was found. It is concluded that the use of fluoride toothpaste by young children in fluoridated areas is unlikely to produce aesthetically unacceptable levels of enamel fluorosis.
本研究评估了在氟化物添加地区使用含氟牙膏对牙釉质形成的影响。比较了在氟化物添加城市（伯明翰）出生并长大的251名9至10岁儿童与在非氟化物添加城市（利兹）出生并长大的319名类似儿童的牙釉质发育不全患病率。通过使用一种新的摄影技术消除了观察者偏差，使两组的彩色幻灯片能够以随机顺序一起评估。使用旨在记录非特异性发育不全的杰克逊 - 阿尔 - 阿卢西（J - A）指数和氟斑牙牙面指数（TSIF）进行评分。将两者与使用J - A指数的传统临床记录结果进行比较。结果表明，摄影方法具有高度可重复性，比传统记录更敏感，并且在氟化物添加地区显示出更高水平的轻度氟斑牙。然而，未发现氟斑牙更高等级增加的证据。得出的结论是，在氟化物添加地区幼儿使用含氟牙膏不太可能产生美学上不可接受的牙釉质氟斑牙水平。
