title: Prevalence of enamel developmental defects in a group of 11- and 12-year-old children in South Wales.
abstract: The prevalence of enamel developmental defects was assessed in 579 children aged 11 and 12 yr using the DDE Index. The teeth were dried prior to the examination and a normal dental operating light was used for illumination. Teeth with some type of defective enamel were seen in 48.9% of children. White/single opacities were present in 26.4% of children and white/diffuse, patchy opacities in 9.9% of children. The enamel was abnormal in 5.74% of all teeth with white/single opacities and white/diffuse, patchy opacities occurring in 1.89% and 1.18% of teeth respectively. There was a significantly higher number of teeth affected by enamel defects in boys (P less than 0.01) and boys tended to have a higher prevalence of yellow opacities compared to girls.
