Factores radiográficos que predisponen Ia resorción radicular de incisivos superiores causada por Ia retención de caninos maxilares.

Objective. Quantify the risk of the position of the impacted canine that caused the resorption of the upper incisors. Methodology. It was a clincal-analitic study, transversal and retrospective for dimensional variables, was used descriptive statistics, to determine association Xi2, for homogeneity and significance P= 0.05, for correlation was used Correlation of Phi and for estabilize risk was used odds ratio. Results. 33 patients was examined, 10 patients in the group with resorption, and 23 patients in the other group with out resorption, between 9 to 15 years old, in the resorption group was shown a eruption pattern so more vertical than the group whit out resorption. Conclusions. The eruption pattern average of 10 ° more horizontal as proposed Sune Ericson 29.5 ° to alpha angle, and 39.1 ° to beta angle mean not risk of resorption, by the contrary, a pattern of more vertical eruption 'Diaz and Piña" 15.7 ° alpha angle and 21.9 ° beta angle.
