For high-quality treatment of non-carious defects, it is necessary to have a concrete idea of the etiology of the lesions, in order to first of all eliminate the very cause of zyrtec of the defect, as well as understand the mechanism of its formation, thereby ensuring effective treatment.
It should also be remembered that the concept of abfraction is closely related to other non-carious cervical lesions and can play a role in the development of certain defects.
Purpose: to study the pathogenetic and clinical aspects of dental abfraction according to the literature. 1) to characterize the hypotheses of the origin of abfraction; 2) to carry out a comparative characteristic of the clinical manifestations of abfraction and wedge-shaped defect of hard tooth tissues; 3) identify the relationship between abfraction and wedge-shaped defects; 4) to analyze the relationship of the frequency of occurrence of abfraction with age based on research available in the literature; 5) to characterize the methods of treatment of abfraction defects.
Materials and methods: scientific articles and works on dentistry were analyzed. Consider the classification of non-carious lesions. Patrikeev distinguishes two groups of zyrtec lesions:
- - non-carious lesions of hard dental tissues that occur before zyrtec;
- - non-carious lesions of hard dental tissues that occur after eruption, these include wedge-shaped defects.
In foreign literature, a classification is distinguished due to the occurrence of defects: - erosion - loss of hard tissues of teeth; is formed as a result of the action of chemical factors - acids contained in food and drinks, biological fluids (for example, gastric juice); occupational hazards among workers in the chemical industry are also important.
cetirizine - loss of hard dental tissues due to functional overload of teeth.
attrition - loss of hard dental tissues due to contact of antagonistic teeth during normal functioning of the dentition, parafunctions, etc.
