Application of Kriging Model to Gear Wear Calculation under Mixed Elastohydrodynamic Lubrication
Machines, 2022 The calculation of tooth wear under mixed elastohydrodynamic lubrication is very complex and requires consideration of many conditions such as load distribution in the tooth meshing zone, micro-convex elastoplastic deformation and tooth surface ...

Australian Dental Journal, 2019 AbstractBackgroundIn an ageing population, tooth wear is likely to increase. It is increasing in prevalence in the younger population and a greater number of patients are retaining their teeth into old age.MethodsThis paper is a narrative review of the clinical presentation, the epidemiology and the restorative intervention for erosive tooth wear.

Tooth Wear and Tribological Investigations in Dentistry
Applied Bionics and Biomechanics, 2022 Dental or tooth wear is a physiological process in the life cycle of teeth. Loss of the occlusal surface may cause excessive tooth wear. Several factors may contribute to tooth wear with different intensities and duration in the oral cavity.

Glasnik Antropoloskog drustva Srbije, 2014 Tooth wear is the loss of dental hard tissue that was not caused by decay and represents a common clinical problem of modern man. In the etiology of dental hard tissue lesions there are three dominant mechanisms that may act synergistically or separately:friction (friction), which is caused by abrasion of exogenous, or attrition of endogenous origin ...

Tooth Wear in Relation to Selected Salivary Variables among a Group of Older Adults
Journal of Baghdad College of Dentistry, 2016 Background: Tooth wear is one of the most concerning problems of the current dental practice especially among older subjects. The aim of this study is to determine the severity of tooth wear and its relation with selected salivary variables (salivary pH ...

Clinical measurement of tooth wear: Tooth Wear Indices
Journal of Clinical and Experimental Dentistry, 2012 Attrition, erosion, and abrasion result in alterations to the tooth and manifest as tooth wear. Each classification corresponds to a different process with specific clinical features. Classifications made so far have no accurate prevalence data because the indexes do not necessarily measure a specific etiology, or because the study populations can be ...
