Objectives: The purpose of the study is to identify dental wear risk factors in the population aged 20 to 25, as well as the possibility to correlate this etiology with the localization of wear mainly at the level of specific dental areas. Method: A standardized sample group of subjects is selected, to whom a questionnaire on the main etiological factors of abrasion included in the literature is administered. For each subject, a pair of plaster models is executed; on them, an analysis shall be carried out, according to the Smith-Knight index, relating to the degree of abrasion on the four surfaces; the results shall be summarized in a Microsoft Excel 2007 database. The statistical analysis, carried out in a specialized manner with the PASW 18 software, shall identify the statistically significant associations between etiology and the occurrence of wear on specific dental groups and surfaces. Results: The etiological factors with statistical signification in the presence of wear on specific dental surfaces are represented by gender, fruit juice, carbonated drinks, vitamin C, iron based preparations, unhealthy habits, excessive teeth brushing, bruxism. Conclusions: The most frequently incriminated factor associated with the occurrence of wear lesions in young patients is represented by the consumption of juice fruit followed by bruxism, but in most of the situations, the subjects display at least 2 risk factors. There are dental surfaces whose wear is associated with specific risk factors.
