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 lesions: etiology, diagnosis, and treatment options

A misaligned bite can be treated with orthodontic treatment, which can prevent future damage to the teeth. Bruxism is one of the most common causes of dental abfractions. Altogether, inappropriate occlusal adjustments may lead to caries initiation, occlusal tooth wear and dentinal hypersentivity. Possible role of tensile stress in the etiology of cervical erosive lesions of teeth.

In extreme cases of Hypersensitivity unresponsive to non-invasive procedures, a restoration might be required. Abfraction lesions of different shapes, widths, and depths, characteristic of their different stages of progression.

Moreover, abfraction lesions may appear deeper than wider depending upon the stage of progression and related etiological factors Figure 1. Stresses caused by occlusal forces is the main etiological factor for noncarious cervical 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.

The various clinical manifestations of abfraction appear to be dependent on the type and severity of the etiological factors leions. Bioengineering studies have discovered the association between wear at the cervical region and occlusal stresses by employing finite elemental analysis or photo-elastic methods [ 232526 ]. Some images are of models, not actual patients. The term biocorrosion has also been proposed to include all forms of chemical, biochemical, and electrochemical degradation.

Correcting malocclusion can help patients when abfraction is caused by improper sbfraction alignment. Clinical and anatomical factors limiting treatment outcomes of gingival recession: Temporomandibular jointsmuscles of mastication and malocclusions — Jaw joints, chewing muscles and bite abnormalities Bruxism Condylar resorption Mandibular dislocation Malocclusion Crossbite Open bite Overbite Overeruption Overjet Prognathia Retrognathia Scissor bite Maxillary hypoplasia Temporomandibular joint dysfunction.

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. Variation in clinical decision making related to caries.

These lesions are multifactorial origin and have many contributing factors which change over time and it is necessary that these potential factors should be evaluated while examining a patient with these lesions.

There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. The value of restorative dentistry to treat NCCLs remains a questionable issue in dentistry.

As discussed previously, successful prevention and management of abfraction or any NCCLs requires an understanding of the risk factors and how these risk factors change over time in individual patients. If left untreated, abfraction can lead to root canal infections, severe decay, and even tooth loss.

I shall present one version of CDA, and a trans-disciplinary research methodology associated with it, and illustrate it through a discussion of aspects of the current financial and economic crisis. New Political Economy 6 89 — Faurclough can sustain a consensus for an open global economy where countries can draw on their deep capital markets to finance faster development which benefits us all, but only if we can provide also a means of responding when these markets fail.

A purely normative or moral critique is not enough if the aim is to change social realities for the better, but values, evaluation and moral critique are a necessary part of critical social science Sayer But it follows from what I have said above that the object of such a piece of research should be constructed in a trans-disciplinary chouliaraji.

Some events consist almost entirely of texts e. Discourses which originate in some fairlough social field or institution e.

My library Help Advanced Book Search. Constructing objects of research is a trans- disciplinary process, so we would need to decide which relevant bodies of social science and theory to engage with. Secondly, they relate critical discourse analysis to social theory, by creating a research agenda in contemporary social life on the basis of narratives of late modernity, fairclougj those of Giddens, Habermas, and Harvey as well as feminist and postmodernist approaches.

The modality is important: Chouliiaraki order of discourse is a social structuring of semiotic difference, a particular social ordering of relationships between different ways of making chouoiaraki — different genres, discourses and styles. For instance, from cultural political economy CPE one might take a theory of structuration which focuses on dialectical relations between structures and strategies, and includes a framework for explaining how, from a variety of strategies, certain ones come to be selected and retained and, in CDA terms, recontextualized and operationalized.

Critical discourse analysis () | Norman Fairclough –

The semiotic dimension of networks of social practices which constitute social fields, institutions, organizations etc.

It situates criticaldiscourse analysis Social wrongs we might focus upon couliaraki In this approach to CDA, analysis is focused on two dialectical relations: The version of CDA which I outline below is well placed to bring a focus on these material- semiotic relations into trans-disciplinary critical social research. Stage 3 leads us to consider whether the social wrong in focus is inherent to the social order, whether it can be addressed within it, or only by changing it.

Identify obstacles to addressing the social wrong. Semiosis is viewed here as an element of the social process which is dialectically related to others.

Critical social analysis can be understood as normative and explanatory critique. References to this book Discourse as Data: CPE also includes ways of addressing the processes of systemic and governance failure which link this historical account of neo-liberalism to the current crisis. Lilie ChouliarakiNorman Fairclough. Stage 4 moves the analysis from negative to positive critique: Finally, they discuss the relationship between systemic-functional linguistics and critical discourse analysis, showing how the analytical strength of each can benefit from the other.

Let us focus on the current period. This version of CDA is associated with a general method which I briefly indicated in the final paragraph of the last section, but the specific methods used for a particular piece of research arise from the theoretical process ahd constructing its object.

Discourse in late modernity: rethinking critical discourse analysis – LSE Research Online

Most explanatory accounts directly or indirectly recognize that semiosis, or discourse, needs to figure in explanations. Remember me on this computer. Skip to main content. There is a long tradition within critical social analysis of viewing social reality as conceptually mediated: But this does not mean that any new strategy for replacing neo-liberalism, whatever that may be, would necessarily address the central wrong at issue in its essentials — a new strategy may not overcome the problems of an economic order with unjust effects e.

This is open to normative critique as a false claim in that the analogy does not stand up to serious economic scrutiny, and as ideological in the sense that it is a discourse which can contribute to sustaining an unjust and inequitable socio-economic order. Let me anticipate the example I shall discuss in the next section: Read, highlight, and take notes, across web, tablet, and phone.

This means that dialectical relations between the material and the semiotic are a necessary focus in both normative and explanatory critique.

Illustration – cjouliaraki research on the financial and economic crisis The events of the financial and economic crisis are relatively clear, but its causes are more contentious.

And this is a trend which must be halted if andd are to avoid the risk of a damaging worldwide spiral of deleveraging and then deglobalisation with adverse consequences for all our economies.
