Prevalence of Dental Erosive Wear and Possible Risk Factors among Adolescents and Adults in Poland - A National Survey.

Purpose: To investigate the prevalence and severity of erosive tooth wear (ETW) and evaluate the determinants of ETW among adolescents and adults in Poland.

Materials and methods: The study covered three age groups of patients: 15 years old, 18 years old, and adults aged 35-44 years. Calibrated examiners measured ETW according to the Basic Erosive Wear Examination (BEWE) scoring system in 6091 patients. The clinical examination of patients was preceded by a socio-medical study based on a questionnaire consisting of items identifying potential risk factors for ETW.

Results: In all age groups, erosive lesions were most common in the form of initial enamel damage; more advanced lesions (BEWE 2 and 3) were rarely observed among 15-year-olds, while in the group of older adolescents and adults, the percentages were 13% and 20%, respectively. Acidic diet, gender, level of education, and medical conditions were statistically significantly associated with ETW in the examined population. The analysis showed that, depending on age, multiple and statistically significant risk factors for ETW become most apparent in the 35-44 age group, especially with regard to general health. This suggests that the long-term impact of factors and their cumulative effects are critical to the development of ETW.

Conclusions: This is the first large, representative study of ETW in Central and Eastern Europe among adolescents and adults, which indicates the relatively rare occurrence and severity of erosive lesions. The present findings support other longitudinal studies supporting the use of the BEWE system as a valuable standard for assessing erosive lesions and related risk factors among different populations at different ages.
