- 2. Objective The effect of water fluoridation upon dental erosion/tooth wear in the UK has not been investigated. Compare the prevalence of tooth wear in 14-year-old schoolchildren in non fluoridated district of north west England. Also the influence of deprivation and tooth brushing was also investigated.
- 3. Design A random sample of 10% of the 14- year-old population in NW England was selected Fluoridation status as determined from water autority postcode listings
- 4. Methods Tooth wear was scored on the labial, incisal and palatal/lingual surfaces of the 12 anterior teeth and the occlusal surfaces of the 1st molars. Table 1. Simplified scoring criteria for tooth wear SCORE 0 no wear into dentine 1 dentine just visible (including cupping) or dentine exposed for less than a third of the surface 2 dentine exposure greater than a third of the surface 3 exposure of pulp or secondary dentine

- 9. Conclusion Children in non-fluoridated districts are 1.5 times more likely to have smooth surface wear compared with children in fluoriated districts. Fluoridation and use of fluoridated toothpaste twice a day provide added protection from dental erosion. The risk of tooth wear is greater with increasing affluence.
