ABSTRACT
PURPOSE:
To investigate the association between palatally displaced canines and cervical skeletal abnormalities by lateral cephalometric, panoramic radiographs and cone-beam CT.METHODS:
One hundred and three patients with palatally displaced canines were chosen as the experimental group, and 103 patients with Class I and normal canines eruption were as the control group.The data of the first four cervical fusions and posterior arch defects were measured on the lateral cephalometrics. The relationship of the cervical skeletal abnormalities and palatally displaced canines was analyzed with SPSS 21.0 software package for Chi-square test.RESULTS:
The incidence of cervical fusion in the experimental group was 71.84%(74 cases), while 15.53% (16 cases) in the control group; the difference between the experimental group and the control group was significant (P<0.001); the incidence of posterior arch defects in the experimental group was 10.68% (11 cases) and 4.85%ï¼5 casesï¼ in the control group; the difference between the experimental group and the control group was not significant.CONCLUSIONS:
There is an obviously increasing occurrence rate of cervical skeletal abnormalities in patients with palatally displaced canines, and cervical vertebra bone abnormalities can be combined with other diagnostic parameters to confirm the situation of impacted canines.
