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.

As much as possible the restorations of NCCL should be restored with minimally invasive method. It is apparent in clinical abgraction that not all patients with abfraction lesions present occlusal wear bruxism or clenchingand not all patients with occlusal wear exhibit NCCLs.
A typical abfraction lesion in a patient with multiple types of NCCLs. Another index for NCCLs has been proposed which not only includes depth of lesion but also the width and angle between the lesion and the occlusal and cervical walls are quantified from 1 to 3 [ 40 ].
Abfraction lesions: etiology, diagnosis, and treatment options
Reproduced from John Wiley and Sons. These lesions occur in both the dentine and enamel of the tooth. Recent systematic reviews have pointed out that the combination of CAF with connective tissue graft CTG provides the best clinical outcomes for root coverage when appropriately performed.
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 tubules by mineral deposits. This reduces sensitivity and restores the tooth structure. 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.
Baysan A, Lynch E. The Causes of Abfraction If you suffer from teeth grinding or malocclusion, you may be at risk of developing abfractions.
In these cases, CTG prevents the collapse of the flap into the depressions, which could lead to undesirable outcomes of the root coverage procedure. Making sense of sensitivity. Many treatment strategies have been proposed to treat these NCCL lesions.
Elsions you have a dental abfraction, you have probably developed a notch in your tooth near the gum line. In addition to the temporomandibular joint TMJ pain the condition can cause, patients may also suffer tooth loss in the form of abfractions. In cases of abfraction associated with gingival recession, a combined restorative-surgical approach may be performed. Other terms bio-corrosion has also been introduced to include all forms of biochemical and electrochemical degradation As seen in Figure 4 [ 9 ].

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 restoration must recreate not only the contour of the tooth crown abfrxction also the contour of the lost CEJ at the root portion.
The prevalence of NCCLs is greater in incisors and premolars than in canines and molars. This could be achieved with complete patient anamnesis accompanied by a careful clinical examination.
April 4, ; Accepted Date: Examining the prevalence and characteristics of abfractionlike cervical lesions in a population of U. Sometimes the contributing factors leading to erosion or abrasion can also alter the clinical manifestations of these lesions by making the blunt angles and broader outlines and more saucer-shaped lesions. This work is published and licensed by Dove Medical Press Limited.
Overview Abdraction you know that smoking tobacco products can make gum disease get worse faster? Noncarious Cervical Lesions as Abfraction: In cases of asymptomatic teeth, where tooth vitality and function are not compromised, abfraction lesions should be monitored for at least 6 months before any invasive procedure is planned. Effect of lateral excursive movements on the progression of abfraction lesions.
Abfraction lesions are observed primarily on the buccal surfaces and are typically wedge- or V-shaped lesions with clearly defined internal and external angles. Cortellini P, Pini Prato G.
Moreover, very few clinical studies have not provided enough evidence on the relation between Abfraction lesions and occlusal stresses [ 27 – 29 ]. If there is a need for placement of restoration, NCCLs should be restored as minimally invasive as possible.
Support Center Support Center. Dietary erosion results due to high intake of foods or drinks having a variety of acids, from citrus fruits, juices citric acidsoft abfration drinks, wine and other carbonated drinks carbonic acid and other acids. Clinical effectiveness of contemporary adhesives for the restoration of non-carious cervical lesions.
Possible role of tensile stress in the etiology of cervical erosive lesions of teeth.
The clinical relationship between the incidence of occlusal wear and cervical demineralization with NCCL dimensions [ 30 ] has been reported using optical coherence tomography, in which the dentin demineralization promotes the formation of NCCLs from an early stage, whereas occlusal stress is an etiological factor that contributes to the progression of these lesions [ 30 ]. Medical conditions and the use of medications that cause a reduction in salivary flow can aggravate the erosive effect on tooth surfaces.
Abfraction lesions: etiology, diagnosis, and treatment options
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.
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 tubules by mineral deposits.
