Prevalence and associated factors of dental erosion in children and adolescents of a private dental practice.

International Journal of Paediatric Dentistry 2011 Background.  The prevalence of dental erosion seems to be rising in young populations, particularly among individuals of higher socioeconomic status. Aim.  To assess the prevalence and associated factors of dental erosion in children and adolescents of a private dental practice. Design.  A total of 232 participants, aged 2-20 years, were examined. Dietary habits, oral hygiene, and medical data were collected from dental records. Logistic regression analyses were conducted. Results.  Dental erosion prevalence was of 25.43% and was highest on the occlusal surfaces (76%). Associated factors were: frequent consumption of soft drinks (OR = 2.33; 95% CI = 1.01-5.38) and candies (OR = 3.23; 95% CI = 1.25-8.32); and interaction between these two factors (OR = 3.95; 95% CI = 1.60-9.75). On anterior teeth, associated factors were: frequent consumption of fruits (OR = 2.53; 95% CI = 1.09-5.91); and age (OR = 1.07 95% CI = 1.01-1.14). Milk consumption was associated with a lower prevalence of dental erosion (OR = 0.40; 95% CI = 0.17-0.94). Conclusions.  A relatively high prevalence of erosion was found in association with frequent intake of soft drinks, candies, and fruits. The consumption of milk seemed to protect against dental erosion on anterior teeth.
