The aims of the study were to investigate dental erosion prevalence, distribution and severity in Greek preschool children attending public kindergartens in the prefecture of Attica, Greece and to determine the effect of dental caries, oral hygiene level, socio-economic factors, dental behavior, erosion related medication and chronic illness.
Material and methods
A random and stratified sample of 605 Greek preschool children was clinically examined for dental erosion using the Basic Erosive Wear Examination Index (ΒΕWE). Dental caries (dmfs) and Simplified Debris Index were also recorded. The data concerning possible risk indicators were derived by a questionnaire. Zero-inflated Poisson regression was generated to test the predictive effects of the independent variables on dental erosion.
The prevalence of dental erosion was 78.8 %, and the mean and SE of BEWE index was 3.64 ± 0.15. High monthly family income was positively related to ΒΕWE cumulative scores [RR = 1.204 (1.016–1.427)], while high maternal education level [RR = 0.872 (0.771–0.986)] and poor oral hygiene level [DI-s, RR = 0.584 (0.450–0.756)] showed a negative association.
Dental erosion is a common oral disease in Greek preschool children in Attica, related to oral hygiene and socio-economic factors.
Programs aimed at erosion prevention should begin at an early age for all children.
