A total of 278 children aged 13 years in 1980, who lived in an area where preventive programs and professional attitudes towards restorative treatment had changed over a 10-year period, were dentally examined in 1980, 1981, and 1982. Different preventive treatments were given to the children, to decrease the variation in dental caries. The development of new lesions and the rate of progression of existing lesions were studied by means of bitewing radiographs. Ninety-four per cent of the surfaces remained unchanged. Of the surfaces diagnosed as carious at 13 years of age no progression had occurred in 63%, and 86% of enamel lesions remained within the enamel. Although caries progression was slow in this population, the variation in dental caries was only slightly altered.
1980年对居住在某地区的278名13岁儿童进行了牙科检查，该地区的预防项目和对修复治疗的专业态度在10年期间发生了变化。这些儿童在1980年、1981年和1982年接受了不同的预防治疗，以减少龋齿的差异。通过咬合翼片研究新病变的发展和现有病变的进展速度。94%的表面保持不变。在13岁时被诊断为龋齿的表面中，63%没有进展，86%的釉质病变仍局限于釉质内。尽管该人群中龋齿进展缓慢，但龋齿差异仅略有改变。
