ABSTRACT


Aim

To evaluate the association between the mesially displaced maxillary first premolar (MDP) and the early displacement
of the adjacent permanent canine (EDC) before their eruption.

Methods

A sample of 1247 subjects in the
intermediate mixed dentition stage was assessed for the presence of MDP and EDC. All subjects were divided into two groups: MDP
group and noMDP group. For each subject two angular measurements (premolar-occlusal plane and premolar-midline
angles) were analysed on panoramic radiographs. The chi-square test with Yates correction was performed to compare the prevalence
rate of EDC in MDP (MDP-EDC) and noMDP groups. The statistical comparisons for the values of and angles between
MDP vs noMDP, MDP vs MDP-EDC, and noMDP vs MDP-EDC groups were performed by means of ANOVA with Bonferroni correction.

Results

The prevalence rate of EDC in the MDP group was significantly greater than in the noMDP group (66 vs.
12.1). MDP-EDC group showed a significantly larger angle than in the MDP group resulting in an increased mesial
inclination of displaced premolars.

Conclusion

MDP can be considered a dental anomaly associated to maxillary canine
displacement.
