Associated with non-dental objects eg hair grips 9or overly vigorous tooth brushing 8. A comparison of patterns of tooth wear with aetiological factors. Self-induced vomiting increases the risk of dental erosion by a factor of 5.

These lesions occur in both the dentine and enamel of the tooth. However, they lack comprehensiveness as they cannot measure the rate of progression and cannot monitor all teeth affected by ventales.

A Review abfraccciones the Literature. More active restorative treatment involving simple restorations Fig. The description of the dental restorative management is outside the scope of this article. An alternative treatment in cases with advanced localized attrition.

Stomach acid can also enter the oral cavity during vomiting episodes due to alcohol hangovers, chronic alcoholism, morning sickness associated with pregnancy, eating disorders such as anorexia and bulimia nervosa 11 and with voluntary regurgitation or rumination Acidic environments for work or leisure may expose patients to factors which cause tooth surface loss.

Adapted from Kelleher and Bishop; 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.

Clinical features of erosive lesions abfraccions The acid that causes erosive wear may be classified as intrinsic or extrinsic 10 depending on the source of the acid from either the stomach intrinsic or the diet and other environmental sources extrinsic. National Center for Biotechnology InformationU. One theory of its clinical features suggests that the lesions only form above the cementoenamel junction CEJ which is where the enamel and cementum meet on abfraccioens tooth.

The causes of erosive lesions are varied Table 2. A representative image of the samples under white and laser illumination shows that although there are visible stains in the left portion of each sample due the dye from the cola beverage, structural changes are difficult to assess with the naked eye. The loss by wear of tooth substance or a restoration caused by mastication or contact between occluding or approximal surfaces. In statements such as these there is no comment on whether the lesions occur above or below the CEJ.

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.

Drinks vary in their resistance to the buffering effect of saliva. Terms such as erosion, abrasion, attrition 3 and abfraction have traditionally been used to describe pathological loss of tooth tissue, reflecting some aetiological factors associated with such occurrences. Carbonated drink, such as colas and lemonades are also very acidic and hence have significant erosive potential. This occurs because the white enamel has eroded away to reveal the yellowish dentin beneath.

Shiny facets or wear on the teeth or restorations may also be observed. Teeth will begin to appear with a broad rounded concavity, and the gaps between teeth will become larger. West Indian Med J.

From Wikipedia, the free encyclopedia. Management The provision of restorative dental care requires a multi-disciplinary approach and may encompass treatment ranging from simple restorations to comprehensive full mouth rehabilitation. Table 1 Definitions of the aetiological factors in tooth surface loss. When looking at abfraction lesions there are generally three shapes in which they appear, appearing as either wedge, saucer or mixed patterns.

Oral mucosa — Lining of mouth. Chronic periodontitis Localized aggressive periodontitis Generalized aggressive periodontitis Periodontitis as a manifestation of systemic disease Necrotizing periodontal diseases Abscesses of the periodontium Combined periodontic-endodontic lesions.
