title: Dental caries in 12-year-old children in Salford, UK: changes over 28 years.
abstract: 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.
