Le résumé fourni par la source

Abstract: Background/Objectives: This study aims to study the prevalence of tooth wear (TW) in a sample of patients seeking the Screening and Urgency appointment at Egas Moniz Dental Clinic (EMDC) and correlate TW with risk factors. Methods: The database created with the collected information was used for descriptive and inferential statistical analysis. Data from 2266 patients, collected between 2021 and 2023, was analyzed for the presence of tooth wear, its different types and its correlation with risk factors. Results: The prevalence of dental wear was found to be 54.7%, with attrition (24.1%) being the most prevalent lesion, and erosion (2.7%) the least prevalent. Concerning risk predictors for tooth wear, age, decreased DVO, antacids, mastigation difficulties, drugs and use of mouthwash were positively associated. Conclusions: It was concluded that TW is prev-alent and increases with age, underscoring the necessity for timely and accurate diagnosis to minimise its progression. Additionally, it is crucial to conduct a thorough evaluation of the risk factors involved, to implement effective preventive measures and treatment strategies.
