| dc.description.abstract | Objective: to identify the risk factors of severe dental attrition in patients who
attended public and private dental care institutions in the city of Cuenca-Ecuador.
Materials and methods: were analyzed 237 adult patients, 79 cases, with dental
attrition grades 2, 3 and 4 according to the Smith and Knight index and 158 controls
with attrition grades 0 and 1. A clinical and photographic examination was carried out
to determine the relationship between dental attrition and factors such as age, sex,
origin, number of residual teeth, salivary pH and bruxism. Results: after a bivariate
analysis, it was evident that patients older than 25 years (OR= 2,47; IC= 1,41 – 4,35;
X2= 10,21; p= 0,001), with less than 20 teeth in the mouth ((OR= 4,95; IC= 1,47 – 16,62;
X2= 7,97; p= 0,004 ) and with bruxism (OR= 2,64; IC= 1,45 – 4,81; X2= 10,49; p= 0,001)
are more likely to have severe tooth attrition. After a binary logistic regression this
relationship was confirmed: patients older than 25 years (OR= 2,03; IC= 1,08 – 3,818)
with less than 20 teeth in the mouth (OR= 3,90; IC= 1,07 – 14,19) and with bruxism (OR=
3,22; IC= 1,70 – 6,10), however a very low predictive capacity of the adjusted variables
was observed according to R-square of Cox and Snell (0.123) and Nagelkerke’s R-square
(0.172). Conclusions: advanced age, minor quantity of teeth in mouth and bruxism
increased the possibility of presenting dental severe attrition in the analyzed patients.
While the masculine sex, the rural origin and the salivary critical pH (less than 6) do not
behave as factors of risk. | |
