Abstract
GONZALEZ MARTINEZ, Farith et al. Inflamatory root resorption in orthodontic treatment subjects. Cartagena (Colombia). Salud, Barranquilla [online]. 2012, vol.28, n.3, pp.382-390. ISSN 0120-5552.
Objective: To determine the occurrence of root resorption in subjects undergoing tooth movement with orthodontic four techniques. Materials and method: A cohort study with up to one year, evaluating root resorption in orthodontic four techniques. The measurements were made on 176 teeth, using the scale of reabsorption of Levander and rots. Periapical radiographs using three in each individual, which were taken every three months. The data were analyzed using proportions of incidence. To compare the results obtained in each of the techniques are used the risk ratio (RR) with confidence intervals 95 %, the Kruskal Wallis, Mc-Nemar and Fischer"s test. We performed a multivariable logistic regression analysis. Results: The incidence of inflammatory resorption was 68.2, appearing at nine and twelve months, showing contour changes in the first grade in 8.5 % and second grade in 2.8 %. In the teeth subjected to edgewise technique was found 3.3 times higher risk of root resorption compared with other techniques. Conclusions: There is evidence of inflammatory resorption in the contour of the root in teeth subjected to tooth movement during orthodontic treatment, however, these are considered mild and depend on each technique used mechanotherapy.
