Dentin exposure may be the result of attrition, abrasion, erosion or
abfraction. Denudation of root surface due to gingival recession or non-surgical and surgical periodontal treatment can also cause Dentin Hypersensitivity.
Tooth surface loss is a composite terminology which broadly covers non-carious tooth surface loss due to attrition, abrasion,
abfraction and erosion.1,2
There are also a few other possibilities for using the quantitative analysis of the intraoral structures and tissue conditions such as dental enamel and dental caries [86], dental
abfraction and attrition [98], enamel erosion [101], enamel demineralization [109], thickness of dentin layer [121], and soft tissues [173].
Unattended compromised anterior guidance for longer durations can initiate attrition and
abfraction of posterior teeth, periodontal diseases due to trauma from occlusion, and temporomandibular joint disorders.
The role of cuspal flexure in the development of
abfraction lesions: A finite element study.
Attrition, abrasion, corrosion and
abfraction revisited: a new perspective on tooth surface lesions.
Signs of excessive tooth flexure can be excessive enamel crazing, tooth and restoration wear, tooth and restoration fracture, microleakage at restoration margins, recession and
abfraction lesions.
Sleep bruxism can cause severe attrition that leads to exposed dentin,
abfraction, tooth mobility and tooth fracture.

abfraction. Biomed Mater Eng.
Effect of root morphology on biomechanical behavior of premolars associated with
abfraction lesions and different loading types.
This exposure can be the result of numerous etiologic factors that include abrasion, erosion, attrition,
abfraction, and gingival recession.
There are no cavities, dental enamel hypoplasia, erosions, or
abfraction lesions, which reveals a good state of oral health.
