Abstract

Background. Both positive and negative associations between developmental enamel defects (DED) and dental caries have been reported in the literature.
Objectives. The aim of this study was to assess the prevalence of DED of permanent dentition and its association with dental caries in schoolchildren living in Poznań (Wielkopolskie Voivodeship, Poland).
Material and Methods. A total of 2,522 6th grade children and 3,112 1st grade children were examined. Developmental enamel defects were described using the modified Developmental Defects of Enamel Index. Dental caries experience was assessed in accordance with the number of decayed, missing and filled teeth (DMFT).
Results. The study revealed 475 children (9.6%) to have at least 1 enamel defect of permanent dentition. In 6th-graders, statistical analysis confirmed significant differences between DMFT, DT (decayed teeth) and FT (filled teeth) numbers of various DED groups with subjects affected by diffuse opacities having generally the lowest caries indices and subjects with enamel hypoplasia and/or demarcated opacities having the highest caries indices. In both age groups, dental caries prevalence was statistically significantly higher in subjects with hypoplasia and/or demarcated opacities as compared to subjects without DED or with diffuse opacities (p < 0.05).
Conclusion. The prevalence of DED in the examined population was low and comparable to those reported in regions without fluoridated water. The study confirmed that children affected by diffuse enamel opacities were less susceptible to dental caries, while demarcated opacities and hypoplasia should be considered important dental caries risk factors.
