Therefore, tooth wear is NOT The result of biofilm-induced diseases such as caries A consequence where tooth tissue is lost due to trauma or Alternative terms Other terms for Tooth Wear that you may come across in the literature, see clinically or have heard of before include: Erosive tooth wear (chemical-physical) A combination of erosion (chemical) attrition (physical), abrasion (physical) Accelerated tooth wear – where the rate of wear is significant for a patients age Severe tooth wear – tooth wear that has significant impacts on a patients life ie. self-esteem, limited chewing, sensitivity Clinical appearance of Severe Tooth Wear Epidemiology: Prevalence In the UK, 30.4% in 77% of 20-45% permanen globally adults have t teeth of some wear in children permanen and 2% and have t teeth adolesce severe (Schlueter and Luka nts (Bartlett et al tooth 2018) These are estimates as it is difficult 2013) to determine prevalence wear (ADHS 2009) (proportion of population with condition at point in time) due to inconsistency in recording – different tools used, not systematically monitored, varying definitions. Aetiology of Tooth Wear Attrition Erosion Abrasion Tooth Wear Erosion Dental Erosion Dental erosion, also known as Erosive Tooth Wear (ETW), is defined by the European Federation of Conservative Dentistry as: The chemical loss of mineralised tooth tissue caused by exposure to acids not derived from oral bacteria (Schlueter et al 2020). Sources of acids that can contribute to dental erosion: Intrinsic Extrinsic Acids Acids Acids Ph
