Tooth Wear 1 Miss Felix Oral and Dental Sciences Tooth Wear Lectures and Assessments Lectures:  Tooth Wear 1: Pre-recorded + workbook  Tooth Wear 2: Pre-recorded + quiz  Tooth Wear 3: Live + case studies to apply theory Assessments:  Formative: workbook, quiz and case studies  Summative: E-assessment and or cases Intended learning outcomes By the end of the session, students should be able to: Define tooth wear Describe the key aetiological factors of tooth wear Outline the significance of tooth wear for oral health GDC Learning Outcomes: 1.1.2, 1.1.4, 1.1.8, 1.7.7, 1.10.1, 1.10.2, 1.10.3, 1.10.4, 1.10.6 Definition of Tooth Wear (TW) Tooth wear has been defined by the European Federation of Conservative Dentistry as: Tooth wear is the cumulative loss of mineralised tooth tissue (enamel, dentine and cementum) due to physical or chemical-physical processes (Schlueter et al 2020). 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 resorption 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 Tooth surface loss - discourage clinically as other reasons for loss of tooth structure Clinical appearance of Severe Tooth Wear Epidemiology: Prevalence In the UK, 30.4% in 77% of adults 20-45% permanent globally in have some teeth of wear and 2% permanent children and teeth have severe adolescents tooth wear (Schlueter and Luka 2018) (Bartlett et al 2013) (ADHS 2009) These are estimates as it is difficult to determine prevalence (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 Abrasio Erosion n 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 Extrinsi Acids c Acids Acids Ph
