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.

Abfraction Lesion: Causes and Treatment
In all the restorative systems available in dentistry, the most preferred is adhesive systems, specifically RBCs due to their esthetic results and more conservative approach [ 57 ].
If there is a need for placement of restoration, NCCLs should be restored as minimally invasive as possible. This could be achieved with complete patient anamnesis accompanied by a careful clinical examination.
Our teeth wear down over time as a result of how hard we brush our teeth, the types of foods and drinks we consume, and more. Restorations of Resin-based composites RBCs and Resin-modified glass ionomer cement RMGIC showed significant reduced dentinal hypersensitivity initially, but reported increased sensitivity of the restored tooth to air and cold when evaluated after 6 months [ 51 ]. In extreme cases of Hypersensitivity unresponsive to non-invasive procedures, a restoration might be required.
Tensile stress from malocclusion and masticatory forces was initially proposed as the primary factor in NCCLs; 3 shortly thereafter, these lesions were termed as abfraction lesions.
The Causes of Abfraction If you suffer from teeth grinding or malocclusion, you may be at risk of developing abfractions.
As with all forms of tooth wear, it is critical to consider the age of the individual and the expected rate of tooth wear. Approaches to determine lesion activity include the use of standardized intra-oral photographs, study models, and measurement of lesion dimensions over time.
However, abfraction develops when the teeth are misaligned, a condition called malocclusion. If sensitivity persists, the exposed dentin may require therapeutic treatment to relieve or eliminate the discomfort.
Other treatment options are reviewed below and include the following: It is also noticed as unusual phenomena in individuals exposed to industrial work environment leading to exposure of industrial acidic fumes or droplets e.
Abfraction – Wikipedia
In some cases the repair or remineralization is insufficient, and the sensitivity persists, in those cases the exposed dentin should be treated to abfrachion discomfort to the patient [ 4546 ]. Please leave this field blank: When looking at abfraction lesions there are generally three shapes in which they appear, appearing as either wedge, saucer or mixed patterns.
Examining tooth flexure effects on cervical restorations: Activity assessment can also be performed by using a scratch test. Periapical, mandibular and maxillary hard tissues — Bones of jaws Agnathia Alveolar osteitis Buccal exostosis Cherubism Idiopathic osteosclerosis Mandibular fracture Microgenia Micrognathia Intraosseous cysts Odontogenic: Abfeaction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay non-carious cervical lesions.
The full leions of this license are abfracton at https: Noncarious cervical lesions NCCLs develop as a result of normal and abnormal or pathological wear and cause abfraction, abrasion, and erosion or chemical degradation of dental tissues.

In most cases of lesions associated with gingival recession, there is a loss of the hard tissues of the tooth crown causing the CEJ to disappear, and root coverage procedures are not effective at treating these crown defects. However, there is no clinical evidence to support this type of clinical interventions to treat cases of abfraction lesions.
A predisposition to failure of restorations placed in NCCL area is observed because of the etiology of the lesions. Dental erosion and medical conditions: The activity of abfraction lesions needs to be assessed and considered in the treatment planning process.

However, the effectiveness of this type of intervention is not supported by evidence. The American Cancer Society reports that: Author information Copyright and License information Disclaimer. Clinical effectiveness of contemporary adhesives for the restoration of non-carious cervical lesions. It has been reported that erosion or biocorrosion can also occur by the frequent use of acidic mouth rinses. Temporomandibular jointsmuscles of lesion and abfarction — Jaw joints, chewing muscles and bite abnormalities.
The major reasoning behind the controversy is the similarity of abfraction to other non carious lesions and the prevalence of multiple theories to potentially explain the lesion. Basal cell adenoma Canalicular adenoma Ductal papilloma Monomorphic adenoma Myoepithelioma Oncocytoma Papillary cystadenoma lymphomatosum Pleomorphic adenoma Sebaceous adenoma Malignant: Abfraction lesions are observed primarily on the buccal surfaces and are typically wedge- or V-shaped lesions with clearly defined internal and external angles.
Some esthetic factors in a smile.
The risk of developing these cancers increases as people smoke or chew more often or for a longer time. Benefits of restorative dentistry in treating NCCLs is debatable [ 42 ]. You are viewing the US English site. Dietary erosion occurs due to high consumption of foods or drinks containing a variety of acids, such as those from citrus and other fruits, fruit juices citric acidsoft drinks, wine, and other carbonated drinks carbonic acid and other acids. So the restorative treatment in case of NCCL are planned only if any of following conditions are met:.
These forces put great stress on the teeth near the gum line, where the enamel and cementum of the teeth meet. Understanding the physiologically dynamic process of changes noticed in the cervical regions of the tooth due to age related factors, unnecessary restorative interventions can be avoided [ 38 ].
