Introduction  \nTooth wear (TW) is a common dental health problem with a low rate of public awareness in this regard. Although certain superficial changes in dental hard tissues may be considered part of normal physiological processes [1–3], scientifically, the TW occurs due to the demineralization caused by oral fermentation of carbohydrates [5]. TW is a broad dental term which encompasses various forms of non-carious loss of dental hard tissue with four main subclassifications according to distinct underlying mechanisms, including Erosion, Attrition, Abrasion, and Abfraction [6,7].  \nTW is a clinically observable phenomenon which often poses significant diagnostic and therapeutic challenges, requiring comprehensive assessment and tailored management strategies to address the  \nassociated multifactorial etiology and prevent further deterioration. Historical and contemporary epidemiological studies indicate that early signs of tooth attrition are observed in the vast majority of adults [3–7], but there are also more severe forms which probably affect approximately 10 % of the population. Identification of the underlying cause, determination of the optimal timing to initiate preventive measures, and precise decision-making regarding the necessity for surgical intervention are essential components for effectively planning the long-term management of patients with tooth attrition. These steps ensure tailored care which addresses disease progression and preserves dental functio","cbCaik1wtVP2j5nB","https://ap.wps.com/l/cbCaik1wtVP2j5nB","pdf",3450575,12,"English","# Introduction\n## Background and definitions of tooth wear\n## Clinical relevance and diagnostic/management challenges\n## Mechanisms: attrition, erosion, abrasion, abfraction\n# Methods\n## Systematic search strategy and databases\n## Heterogeneity and meta-analysis approach\n# Results\n## Included studies and global prevalence estimate\n# Conclusion\n## Implications for healthcare prevention and control","[{\"question\":\"What does tooth wear (TW) refer to in this study?\",\"answer\":\"TW is the loss of dental tissue occurring through four mechanisms: attrition, erosion, abrasion, and abfraction.\"},{\"question\":\"How was the global prevalence of tooth wear estimated?\",\"answer\":\"The study used a systematic review and meta-analysis, searching PubMed, WoS, ScienceDirect, Scopus, Embase, and Google Scholar up to November 2024, then applying I2 for heterogeneity and a random-effects model in CMA v2.\"},{\"question\":\"What was the main global prevalence finding?\",\"answer\":\"Across 133 eligible studies (92,153 individuals), the global prevalence of TW was 40.8% (95%CI 36.7–45; I2 99.1).\"},{\"question\":\"Why do the authors emphasize healthcare strategy implementation?\",\"answer\":\"Because TW shows high global prevalence, comprehensive strategies are needed to control TW occurrence and prevent associated complications.\"}]","The global prevalence of tooth wear in general population - a systematic review and meta-analysis | PDF",1790706849]
