title: A comparison of normative and subjective assessment of the child prevalence of developmental defects of enamel amongst 12-year-olds living in the North West Region, UK.
abstract: Analysis of data from a 1996-97 cross sectional epidemiological study of the dental health of a sample of 12-y-old children living in Crewe, in north west England was used to compare normative and subjective assessment of developmental defects of enamel. Five hundred and twenty two 12-y-old children from secondary schools in Crewe were examined. One hundred and eighty two children (34.8%), had home post codes within the optimally fluoridated part of Crewe. Using the Developmental Defects of Enamel Index, 178 children (34%) in Crewe were normatively identified as having enamel defects present on their upper incisors. Thirty five children (6.7%), were unhappy with the appearance of their upper incisors because of marks that would not brush off. Neither the normative nor the subjective assessment of enamel defects demonstrated any difference in prevalence between the fluoridated and non-fluoridated areas. In Crewe, one in 20 children normatively diagnosed as being free from enamel defects were unhappy with the appearance of their upper incisors because of marks that would not brush off. There are differences in perception between dental professionals and 12-y-old children over the presence and relevance of developmental defects of enamel. Further research is required if we are to understand the difference in professional and lay perceptions of developmental defects affecting upper incisor teeth.
