Abstract
Aims: assess the prevalence, extent, severity, and distribution of erosive tooth wear (ETW) in preschoolers of Montevideo. Methods: cross-sectional population-based study of representative sample of public and private educational centers. Sociodemographic, biological, and behavioral aspects were investigated with a self-reported questionnaire to parents / guardians. The examinations were performed by two examiners (Kappa ≥ 0.7). The ETW was registered with modified O´Brien index, reported in percentage and average, confidence interval (CI) 95%. Analysis of association with sex and socio-economic level were carried out. Results: 614 preschoolers were examined. Prevalence: 57.6% [95%CI=52.7-62.5]. Severe ETW: 8.2% [95%CI 5.5-10.9]. ETW extension: 4.8 [95%CI=4.3-5.3]. The most affected surfaces were palatal upper incisors. Preschoolers of high socioeconomic level presented higher ETW than those of low level; 73.1% (95% CI: 61.9-84.2) and 48.4% (95% CI: 39.2-57.7) respectively (≤0.01). Conclusion: ETW prevalence and extent was high. These data can contribute to the modification of measures that aim to control ETW prevalence.
