There are numerous signs of dental erosion, including changes in appearance and sensitivity.
The Classic 3-STEP Technique, a simplified protocol for ADDITIVE adhesive rehabilitations
Regurgitation erosion refers to tooth wear caused by the regurgitation of hydrochloric acid from the stomach. In an erosion model, these patterns are associated with mineral loss from the enamel. The causes of erosive lesions are varied Table 2.
Thus, in addition to the routine medical history, emphasis must be placed on medical conditions and eating disorders that predispose to regurgitation erosion. Caries tooth decay Attrition Abrasion Erosion Hypercementosis tooth resorption External resorptionInternal resorptionRoot resorption. Shiny facets or wear on the teeth or restorations may also be observed. This method has proven sensitive to 10 minutes of acid etching on tooth enamel, which is a lesion so incipient that is not likely to be detected in clinical practice even by a trained dentist, besides it is also sensitive to the erosion progression.
Based on the optical changes induced in eroded tissue by the lesions, in Koshoji et al. As abfraction is still a controversial theory there are abfarcciones ideas on what causes the lesions.

A Paryag 1 From: Basal cell adenoma Canalicular adenoma Ductal papilloma Monomorphic adenoma Myoepithelioma Oncocytoma Papillary cystadenoma lymphomatosum Pleomorphic adenoma Sebaceous adenoma Malignant: Acid erosionalso known as dental erosionis a type of tooth wear. Extra-oral examination may reveal facial signs of alcoholism such as facial flushing and spider angiomas and enlarged parotid glands which can also be an indicator of autoimmune disease or anorexia.
Drinks vary in their resistance to the buffering effect of saliva.
Amalgam restorations in the mouth may be clean and non-tarnished. One theory of its clinical features suggests that the lesions only form above the cementoenamel junction CEJ which is where abfarcciones enamel and cementum meet on a tooth.
Table 3 shows the acidity of some common foods and beverages. In-vivo studies are advantageous in assessing erosion directly from the patient’s mouth. A variety of drinks contribute to dental erosion due to their low pH level. In other projects Wikimedia Commons.

A Review of the Literature. West Indian Med J. ABSTRACT Tooth wear or tooth surface loss is a normal physiological process and occurs throughout life but is considered pathological when the degree of destruction is excessive or the rate of loss is rapid, causing functional, aesthetic or sensitivity problems.
The most common abfeacciones of tooth wear in the Dentalex population is erosion 4. Abfraction The pathologic loss of hard tooth substance caused by biomechanical loading forces.
Tooth surface loss from abrasion, attrition and erosion.
Environmental extrinsic erosion Acidic environments for work or leisure may expose patients to factors which cause tooth surface loss. External resorption Internal resorption Irreversible pulpitis Reversible pulpitis Pulp necrosis Pink tooth of Mummery.
Intrinsic dental erosion, also known as perimolysis, is the process whereby gastric acid from the stomach comes into contact with the teeth. In the anterior teeth, there is increased incisal translucency, incisal chipping and, in moderate to severe cases, cupping out of the incisal edges Figs. Further research has shown that the normal occlusal forces from chewing and swallowing are not sufficient to cause the stress and flexion required to cause abfraction lesions.
It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. Periodontium gingivaperiodontal ligamentcementumalveolus — Gums and tooth-supporting structures.
