PREVALENCIA DE FACETAS DE DESGASTE.

Objective. To evaluate the prevalence of eroding facets. Material and Methods. A descriptive and cross study was made in patients of the Clinica Especializada of the San Martin de Porres University, during the months of April to June 2012. The sample consisted of 245 patients, to whom was conducted a dental examination and a questionnaire was given to evaluate the following factors: patient age, gender, occupation, number of teeth with eroding facets, factors predisposing to the appearance of eroding surfaces. Results. The values obtained show that 77.55% of patients had eroding facets, with no difference between males and females. The most affected age group was patients from 18 to 33 years old (34.74%) followed by the group from 34 to49 years old(31.05%). The teeth most affected were the incisors (43.26%), followed by the canines (28.11%), which also showed increased sensitivity to touch and air blast. Vigorous brushing was the single predisposing factor of significance that was found. [ABSTRACT FROM AUTHOR]
