Abstract

The aim of this study was to compare the frequency of enamel hypoplasia in children with renal disease and healthy children, all of whom live in a fluoridated area. A cross-sectional study was made in 42 children divided into 2 groups. To describe enamel changes, 3 diagnostic criteria were applied: TSIF Index to describe dental fluorosis, Jackson-Al-Alousi Index to describe enamel hypoplasia, and Russell criteria to differentiate mild forms of dental fluorosis and enamel hypoplasia. The frequency of enamel hypoplasia in patients with renal disease was 38.09%. This frequency is smaller than that seen in other studies. There was no difference in the frequency of dental fluorosis between patients with renal disease and patients without renal disease. However the patients with renal disease presented more severe dental fluorosis than children without renal disease.
