The wedge-shaped defect

wedge-shaped defects

The wedge-shaped defect wedge-shaped defects - non-carious lesions occurring in the solid tissues of the teeth and is localized at the necks of the teeth, as well as labial and buccal surfaces, often canines and first premolars.Visually, this manifests itself as a defeat stair shaped like a wedge (hence the wedge-shaped defects), which is formed in the cervical area.Such defects are expressed by small enamel defects, to cleave the whole coronal part.In most cases, a wedge-shaped defect occurs in middle / elderly


Today the main cause of the wedge-shaped defect until the end and not found out.However, most experts inclined to think that this defect is due to various mechanical factors (including toothbrush).There is speculation that irregular horizontal teeth cleaning toothbrush with stiff bristles leads to abrasion of hard tissues of the tooth, as well as the premolars and canines (the most protruding incisors in the dentition) frequently suffer from diseases wedge-shaped defect - th

is assumption is most likely.In addition, the factors influencing the emergence of this disease include periodontitis and retsissiyu gums.Was seen correlation wedge-shaped defects with certain medical conditions and diseases of the psyche (schizophrenia, depression, neuroses, etc..)


Development wedge-shaped defect occurs very slowly over the years, and in most cases the pain is completely absent(patients only indicate a slight defect at the neck of the tooth).In rare cases, it may be shown sensitivity to sweet, warm, cold, touch the toothbrush and other irritants.

At a later stage, a wedge-shaped defect may grow to 3 mm, and the tooth necks are more sensitive.In case of severe lesions of teeth wedge-shaped defects (about 5 mm), affected already the deepest layers of dentin, and sometimes the pulp chamber that when even the minimum load leads to chipping of the tooth crown


Treatment wedgedefect in its early manifestations aimed at stabilizing process (application of 2% solution of sodium fluoride, 10% solution of calcium gluconate, 75% of fluoride toothpaste) and the removal of traumatic factors (except abrasive toothpastes and powders, scrubbing brushes, refusalreadings from the horizontal teeth).

If wedge-shaped defects clearly expressed, made their filling, preferably composite filling materials, since they can close the wedge-shaped defects without prior preparation.With deep defects as possible broke off a tooth crown, it is recommended prosthetics.
