Fatores preditores da inclusão do canino maxilar permanente

Abstract

Objective: The main objective of this study was to evaluate whether impaction of the maxillary permanent canine (IMPC) can be predicted by factors such as sex, class of malocclusion, facial biotype, microdontia/peg-shaped maxillary permanent lateral incisor or congenital missing maxillary permanent lateral incisor. Methods: The initial study sample consisted of 95 children with 9 years old, which were selected from the clinic of the Faculty of Dental Medicine, University of Porto in the period between 2008 and 2010. In April 2014, all participants were asked to return for clinical examination. Agreed to participate in the study 51 children, now with the chronological age of 13-14 years. In the intraoral exam at 2014, the eruption of 13 and 23 was checked. Statistical analyses were performed with the IBM SPSS Statistics 22.0 statistical package. The statistical methods for the associations between each variable and IMPC included chi-square tests.P values less than 0.05 were considered significant. Results: There was no statistically significant differences (p < 0.05) between the studied predictive factors and the eruption of the maxillary permanent canine. Further investigations with large samples should be performed in order to increase our knowledge in this field. Conclusion: No statistically significant differences were found between the predictive variables analyzed and the impaction of the maxillary permanent canine.
