This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the incidence of non-carious tooth surface loss has also shown a rise. Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging. Advanced and excessive wear and tooth surface loss can be defined as pathological in nature, requiring intervention by a dental practitioner. 2018-05-15 Although there are known situations where only one single process causes tooth wear (e.g. nocturnal teeth grinding produces wear by attrition alone), the clinical presentation often results from a combination of tooth wear processes.
This video explains the various forms of non carious tooth wear i.e Attrition, Abrasion, Abfraction, Erosion which significantly affect the long term dental L’attrition et l’abrasion se produisent sur les surfaces occlusales de la dent tandis que l’abfraction se situe au niveau du collet dentaire et l’érosion est située sur la partie interne ou externe de la dent. Si vous presentez un de ces types d’usure, il est très probable que vous obtiendrez bientot les autres formes. A dentist is the right person to tell you why abfraction is caused. The difference between attrition and abfraction is that the abnormal load impacts the teeth at a different location causing tooth flexure. This leads to tooth flexure which results in flaking of the enamel around the neck of the tooth instead of the biting surface. Attrition, abrasion, corrosion and abfraction revisited: A new perspective on tooth surface lesions Regressive changes in Tooth : Attrition, Abrasion, Erosion and Abfraction Regressive alterations are the group of degradative changes in the teeth which occur due to non-bacterial causes and result in wear and tear of the tooth structure with some impairment of function. Let's see some of the commonest regressive alterations of teeth one by one.
The lesion caused by abfraction are V-shaped and the ones by abrasion and attrition are flat.

Attrition and abrasion affect the occlusal part of the tooth, while abrasion occurs at the neck of the tooth, and erosion on the inner or outer part of the tooth. Tooth wear is the result of three processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact) and erosion (dissolution of hard tissue by acidic substances). A further process (abfraction) might potentiate wear by abrasion and/or erosion. Tooth wear may present as abfraction, abrasion, attrition, and erosion. It is well established that the most common cause of attrition is bruxism. According to only a few clinical studies, cervical

is the progressive loss of hard tooth substances caused by mechanical actions other than mastication or tooth-to tooth contacts.
Early research suggested that the cause of the V-shaped lesion was excessive horizontal toothbrushing. Abfraction is another possible etiology and involves occlusal stress, producing cervical cracks that predispose the surface to erosion and abrasion.

Slide 2 - : Aims and Objectives Aim: to ensure delegates understand how tooth tissue loss can be detrimental to dentine hypersensitivity Objectives: By the end of the session you should be able to: Distinguish between erosion, abrasion, attrition and abfraction Determine the causative factors of tooth tissue loss Describe how to prevent further tooth tissue loss Discuss sensitivity theories This article was the first to establish abfraction as a new form of lesion, differing from abrasion, attrition, and erosion. Tooth tissue is gradually weakened causing tissue loss through fracture and chipping or successively worn away leaving a non-carious lesion on the tooth surface. The etiologies of abfraction, abrasion, attrition, and erosion may be interrelated.
