GARCIA, Juan Cardentey et al. Teeth attrition in permanent occlusion. []. , 18, 4, pp. 566-573. ISSN 1561-3194.

Introduction: the development of knowledge concerning trigger mechanisms orB factors that exacerbate mechanical dental attrition resulting from mastication or oral parafunctional habits, its consequences, as well as the interest of its early detection is very important. Objective: to assess the behavior of dental attrition and its relation to the presence of cervical attrition and the alterations of the occlusion guide. Material and Method: an observational, descriptive and cross-sectional research was conducted in patients older than 19 years old with dental attrition attending Dentistry Service of RaC:l SC!nchez University Polyclinic, Pinar del RC-o municipality from January/February 2013; a non-probabilistic sample through criteria was used, 60 patients were chosen, a clinical-oral examination was applied to create an individual clinical chart. Data were collected and analyzed by means of a non-parametric chi square test. Results: degree 2 attrition prevailed; half of patients from this group presented this degree with alteration on functions. Ages from 31 to 40 were the most representative on the sample chosen, where female sex predominated. The majority of patients showed cervical attrition in posterior teeth, while anterior teeth showed no signs. Conclusions: the existence of dental attrition was demonstrated, as well as the relation of this pathology to the alterations of the occlusion guide and the degree of teeth wearing away.
