Concepts of tooth wear have changed dramatically in recent times. Although its prevalence in contemporary populations has not been thoroughly studied, it is increasingly recognized as a significant clinical finding among both older and younger people today. In older people, the longer times for which they remain dentate, as well as their increasing lifespan, would appear to be a risk for advanced tooth wear and a possible need for rehabilitation. There are indications too that tooth wear, especially in children and adolescents, may mainly be a consequence of dental erosion. In this case, the literature points to the global rise in soft drink consumption as a significant etiologic factor. Lifestyle changes, a greater sense of consumerism in society including greater aesthetic demands, chronic diseases, and medications that can result in regurgitation and/or dry mouth, amongst others, are possible reasons to explain the clinical perception of an increasing prevalence of tooth wear in modern society. We invite investigators to contribute original research articles as well as review articles that will foster better understanding of the broad scope of the subject of tooth wear. Potential topics include, but are not limited to:

• Multifacetted nature of tooth wear
• Epidemiology of tooth wear across different populations
• Diagnosis of tooth wear
• Etiology and host-related factors in tooth wear
• Pathogenesis and characteristics of wear experienced under different living conditions, and its natural history
• Preventive strategies for tooth wear at the individual and population levels
• Restorative and rehabilitative strategies, including materials and occlusal implications
