It is an analytical cross-sectional study aimed at assessing the prevalence and risk level of tooth wear using the Basic Erosive Wear Examination Index (BEWE). The BEWE categorizes tooth wear into four levels (0 = no wear, 3 = severe wear), and risk levels are determined by the cumulative score.\n\nPrimary outcome: the prevalence of tooth wear and associated risk levels. Secondary outcomes: identifying predictive risk factors and assessing the Oral Health Impact Profile (OHIP) for patients diagnosed with tooth wear.
