A sample of 111 12-year-old children in Salford, UK was examined in 1988, and the findings compared with those of a survey carried out in 1960 of 12-year-old children in the same city. Between 1960 and 1988, the mean DMFT of the boys fell from 6.04 to 2.34 and that of the girls from 6.54 to 3.40. All types of teeth were affected by caries in 1960 but in 1988 none of the canines and mandibular lateral incisors were affected. In 1960 the permanent first molars contributed 57% of the boys' and 54% of the girls' total DMFT while in 1988 they contributed 87% of the boys' and 73% of the girls' DMFT. Jackson's Treatment Index showed that the dental services were making a greater impact in 1988; for the boys it rose from 29.5 to 63.2 and for the girls from 27.8 to 62.3.
1988年，对英国索尔福德的111名12岁儿童进行了检查，并将检查结果与1960年在同一城市对12岁儿童进行的一项调查结果进行了比较。1960年至1988年期间，男孩的平均龋失补牙数（DMFT）从6.04降至2.34，女孩的则从6.54降至3.40。1960年所有类型的牙齿都受到龋齿影响，但1988年犬齿和下颌侧切牙均未受影响。1960年，恒牙第一磨牙占男孩总DMFT的57%，占女孩总DMFT的54%，而1988年，它们分别占男孩总DMFT的87%和女孩总DMFT的73%。杰克逊治疗指数表明，1988年牙科服务产生了更大影响；男孩的指数从29.5升至63.2，女孩的从27.8升至62.3。
