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. Multiple factors are seen as contributing to the development of noncarious cervical lesions (NCCLs). The term abfraction is applied to these lesions in relation to. Evidence supports that abfraction lesions, as any NCCLs, have a multifactorial etiology. Particularly, the cervical wear of abfraction can occur.

Characteristics of non-carious cervical lesions: The lesions occur gradually, making the tooth appear to vanish over time. The defense mechanisms activated in teeth as a result of wear include the formation of reactionary and reparative dentin and the obstruction of exposed dentinal abfractino by mineral deposits.

Wear facets may be found in the enamel, primary dentin, physiologic secondary dentin, and reparative sclerotic dentin. May 25, ; Published Date: Bruxism is one of the most common causes of dental abfractions. If you have a dental abfraction, you have probably developed a notch in your tooth near the gum line. Occlusal adjustment and occlusal splints As a result of the reported associations between occlusal stress and abfraction lesions, occlusal adjustment has been proposed as an alternative treatment to prevent the initiation and progression of these lesions and to minimize failure of cervical restorations.

Smokers are six times lesionw likely than nonsmokers to develop these cancers. Lesionw aetiology of the non-carious cervical lesion. Attrition, abrasion, corrosion and abfraction revisited: Abfractions are not cavities, but instead non-carious cervical lesions, or NCCL. Abcraction of root coverage. The activity of abfraction lesions needs to be assessed lesjons considered in the treatment planning process. Proper recognition and treatment planning of the prospective etiological factors are important for proper diagnosis and treatment planning.

Also abfractoin these circumstances, when abfraction lesions are painless and do not affect esthetics, there is normally no complaint from the patient. There is no conclusive evidence for reliable, predictable, and successful treatment regimens for abfraction lesions. It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamelespecially at the cementoenamel junction CEJundergoes large amounts of stress, causing micro fractures and tooth tissue loss.

As a result of the reported associations between occlusal stress and abfraction lesions, occlusal adjustment has been proposed as an alternative treatment to prevent the initiation and progression of these lesions and to minimize failure of cervical restorations.

Esthetic and predictable treatment of abfraction lesions. Restorations should allow for the establishment of a physicomechanical barrier for dentinal protection against the causes of sensitivity or etiological risk factors leading to biocorrosion of the enamelā€”dentin substrates.


Abfraction, attrition, erosion is due to normal and abnormal or pathological wear of the dental tissues [ 6 ]. Eur J Oral Sci. Clinical assessment of non carious cervical lesion using swept-source optical coherence tomography. Treatment of cervical sensitivity with a root sealant. Individuals suffering from medical conditions and are on medications like anti-sialagogues have reduced rate of saliva secretion leading to erosive effect xbfraction tooth surfaces.

This review aims to provide insights on where abfraction lesions stand in research and clinical practice today by presenting the current knowledge and treatment options for these lesions. Particularly, the cervical wear of abfraction can occur as a result of normal and abnormal tooth function and may also be accompanied by pathological wear, such as abrasion and erosion. Dentinal desensitizers, such as GLUMA Heraeus Kulzer GmbH, Hanau, Germanycontain hydroxyethyl methacrylate that blocks the tubules and glutaraldehyde that causes the coagulation of plasma proteins of the dentinal fluid, thus resulting in a decrease of permeability.

Abfraction lesions are more prevalent in the adult age population of 40 years old affecting mainly the premolar teeth. Correcting malocclusion can help patients abfratcion abfraction is caused by improper bite alignment.

Possible role of tensile stress in the etiology of cervical erosive lesions of teeth. Furthermore, several indices of tooth wear have been proposed for recording and monitoring the progression of abfraction lesions or any NCCLs.

The various clinical manifestations of abfraction appear to be dependent on the type and severity of the etiological factors involved. This will cause a great deal of pain and may eventually kill the nerve. One study suggests that Abfraction is due to flexure in the cervical area of tooth from the occlusal compressive forces and tensile stresses leading to microfractures of enamel and dentin at the hydroxyapatite level in turn resulting further fatigue and deformity of tooth structure [ 17 – 19 ] and some researchers even proposed that the occlusal forces on the tooth from chewing and swallowing leading to concentration of stress and flexion in the area where the enamel and cementum meet [ 39 ], as the etiological factor of Abfraction [ 820 ].


Diagnosis of erosion may not be easily accomplished because patients may not volunteer information as in cases of eating disorders, or patients may not link heartburn or stomach upsets with teeth defects.

lesipns Variation in clinical decision making related to caries. In addition to a thorough medical history, which should include an evaluation for gastroesophageal reflux disease, eating disorders, and dietary contributors, one should evaluate occlusion, parafunction, and oral habits, including occupational and ritual behaviors.

Squamous cell papilloma Keratoacanthoma Malignant: At present, considering a single factor to be the cause of NCCLs is not correct, instead the recent evidence suggests that NCCLs are multifactorial and depends on the patient factors for the various degrees of tooth structure loss [ 10 – 13 ].

The assessment of lesion activity can be performed every 6 months to 12 months and during regular hygiene visits. Nevertheless, there is no evidence that restorative treatment of NCCLs is effective in impeding further development of the lesions, and therefore, restorations cannot be used as a preventive measure to stop lesion progression. Moreover, abfraction lesions may appear deeper than wider depending upon the stage of ,esions and related etiological factors Figure 1.
