The aim of this study is to detect the prevalence of tooth wear (All forms of cumulative surface loss of mineralized tooth substance loss due to physical and chemico-mechanical process according to the definition of the European Organization for Caries Research (ORCA) and the International Cariology Research Group for Dental Research (IADR) i.e.: attrition, erosion and abrasion) among middle aged adult patients attending educational hospital at the Faculty of Dentistry, Cairo University and to analyze the distribution of lesions by gender and age, frequency of acidic foods and drinks consumption, medicine usage, chewing habits, systemic diseases, tooth brushing habits, and family socio economic status. Moreover, to evaluate the quality of life among middle aged elderly patients in relation to existence of tooth wear.
The study focuses on middle-aged adult patients (31-45 years) attending the Faculty of Dentistry at Cairo University during 2025-2026. 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.
Primary 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. All participants will be examined, and those with a BEWE score above 0 will be considered affected. Risk levels will be stratified as no risk, low, medium, or high.

| Prevalence and risk level of tooth wear | Prevalence of wear will be tested using Basic erosive wear examination index (BEWE) 0 =no tooth wear
To calculate prevalence Examined participants with score 0 will represent unaffected population % Examined participants with scores above 0 will represent the affected population % Stratification of risk levels will be done for affected population according to BEWE risk levels. The sum of the scores is calculated to provide the BEWE risk level (0-14) 0-2 = no risk 3-8= low risk 9-13= medium risk 14= high risk | 1 year |

| Oral Health-Related Quality of Life (OHRQoL) using a questionnaire | OHRQoL will be measured using Oral Health Index Profile (OHIP-14) questionnaire OHIP-14 is a 14-item questionnaire that measures : Functional limitation Physical pain Phycological discomfort Physical disability Social disability Phycological disability Handicap It measures responses on a Likert scale (0-4) with the following values: Never (0) Hardly ever (1) Occasionally (2) Frequently (3) Very frequently (4) Points for each response are summed so that each patient can score a minimum of 0 points and a maximum of 56 points. Low scores indicate better self-perceived quality of life, and high scores indicate worse self-perception of oral quality of life Participants diagnosed with tooth wear | 1 year |
