RESUMO:

Objective:
To compare the angular changes of the maxillary canines, first and second
premolars with and without palatally displaced canine ( PDC), during their development
and eruptive process. Materials and Methods: A longitudinal and retrospective study,
carried out from the radiographic analysis of the online database of a private
orthodontic clinic. The sample consisted of 39 patients who had at least two sequential
panoramic radiographs, the first one performed i n the mixed dentition phase and the
final one at the minimum age of 10 years. The data were counted by hemiarches and
divided into two groups: WITH and WITHOUT PDC . In the end, 75 hemiarches were
included, in which t he angular measurement of the long axis of the dental elements
involved in relation to the midline and the stage of dental development were performed.
The paired t test was used for the comparison of intragroup angular measurements,
and the t tests and One Way ANOVA for the intergroup comparison . Finally, the linear
regression of the independent variables was analyzed. Values of p ≤ 0.05 were
considered significant . Results: Longitudinally, canines with palatally displaced and
second premolars of both groups did not change the angular mean significantly, while
canines without the eruptive disorder and first premolars of both groups reduced the
angular mean significantly in the observed period. In the intergroup evaluation, c anines
with eruptive disorder presented angular means significantly higher than canines
without the disorder in the final radiograph. In the initial radiograph, maxillary canines
with palatally displaced were more angled than those that do not present alte ration of
trajectory when they were in stage of dental development "E". In addition, the initial
angulation of the upper canines significantly influenced their final angulation.
Conclusion: Palatally displaced canine do not align in the same way as canines
without eruptive disorder. Angular differences between canines with and without
ectopic eruption are noticeable at the "E" stage of dental development.
