The progress of dental erosion is largely inferred from cross-sectional data. A random sample of 1753 12-year-olds from all state schools in Leicestershire was examined, and 2 years later 1308 were located and re-examined. The second sample had similar demographic characteristics to the first. All longitudinal comparisons were made within the second sample at the 2 examinations.

Erosion was found in 56% at age 12, increasing to 64% at 14; those with deep enamel exposure increased from 4.9% to 13.1%, and those with dentine exposure, from 2.4% to 8.7%. There was significantly more erosion in boys than girls. Over the 2 years, 27% developed new or more advanced erosion. The lowest increases were seen in Asian girls. Overall, there were greater increases in the most deprived children, and in white males.
