Tooth wear is predominantly the result of a combination of three processes; attrition, abrasion and erosion. [3] These forms of tooth wear can further lead to a condition known as abfraction , [ 3 ] where by tooth tissue is 'fractured' due to stress lesions caused by extrinsic forces on the enamel.
Thus, if erosion and bruxism both exist, surface loss due to attrition is faster. Severe attrition in young patients is usually associated with erosive factors in their diets. [7] The different physiological processes of tooth wear (abrasion, attrition and erosion) usually occur simultaneously and rarely work individually.
Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel , especially at the cementoenamel junction (CEJ), undergoes large amounts of stress ...
The aetiology of dental abrasion can be due to a single stimulus or, as in most cases, multi-factorial. [6] The most common cause of dental abrasion is the combination of mechanical and chemical wear. Tooth brushing is the most common cause of dental abrasion, which is found to develop along the gingival margin, due to vigorous brushing in this ...
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
Traditionally, the believed aetiological causes for NCCL have been erosion and abrasion. [2] However, in the past few decades, abfraction has been implicated as a possible contributing factor of NCCLs as well. Bartlett and Shah propose that NCCLs arise from a combination of all three factors: erosion, abrasion and possibly abfraction as well. [3]
Attrition (dental), loss of tooth structure by mechanical forces from opposing teeth; Attrition (erosion), the wearing away of rocks in rivers or the sea; Attrition, also known as Final Mission, 2018 american film; Imperfect contrition, also known as attrition, in Catholic theology; Customer attrition, loss of business clients or customers
Abfraction is another type of tooth wear that is postulated to occur with bruxism, although some still argue whether this type of tooth wear is a reality. [15] Abfraction cavities are said to occur usually on the facial aspect of teeth, in the cervical region as V-shaped defects caused by flexing of the tooth under occlusal forces.
