FACTORS INVOLVED IN CERVICAL EROSIONS

Dental wear is a universal experience. It is accepted today that the phenomena of dental wear knows a significant increase especially in young people. Although the causes are not well defined, it is supposed to act as a category of “predisposing factors” specific to age and civilization as well as a category of causal factors. Dental loss of a different etiology than the caries is a normal physiological process carried out by lifetime. Identifying the causes involved in this process is particularly important in order to predict the long-term behaviour of both teeth and restorative treatments. It is difficult to establish the limit to which tissue loss is considered pathological because the notion of normal is still a source of controversy. Material and Method : The study was conducted between 20162017 on a sample of 56 subjects out of a total of 794 persons with erosions. Results and Discussion: Patients were ranked in relation to the type of odontal lesion and the probable etiology incriminated. To determine the factors that caused erosive lesions, we performed the main paraclinical tests using the Dentobuff kit, the determination of salivary flow and the food survey. Conclusions: Acid erosion, by definition, is caused by the action of alimentary or gastric acids dissolving dental surfaces, which also result from our analysis.
