ABSTRACT
The prevalence and interest of dental erosion seems to be rising in children all over the world. Thus, This study was performed to investigate the prevalence and severity of dental erosion in the primary molars at terminal stage nearing exfoliation, and associated risk factors. An examination was performed on 788 children using modified Linkosalo & Markkanen system, and questionnaires were gained. Association between dental erosion and the risk factors were statistically analyzed with chi-squared test and logistic regression analysis at a significance level of p < 0.05. As a result, 213 children (27%) showed dental erosion, and the mandibular left first primary molar was the most influenced tooth. According to the analysis of risk factors, frequent intake of carbonated drinks and fruit juices showed significant development of erosion (p < 0.05), and using straw for drinking fruit juices showed significant a reduction of erosion (p < 0.05).
