ABSTRACT
Objective:
To localize the impacted maxillary canine and to observe the root resorption of adjacent incisor in 3 dimen-sions using cone beam computed tomography(CBCT).Methods:
92 impacted maxillary canines in 63 patients were scanned by CBCT.The three-dimensional images were obtained by multiplanar reconstructions(MPR).The cusp tip of each impacted canine was localized and set to the X,Y and Z planes after the observation of sagittal,coronal and axial views.The root resorption of adjacent in-cisors was observed.Results:
In the X-axis,92% of impactions were mesial by 1 0.4 to 1 5.1 mm,8% distal by 2 to 5 mm;in the Z-axis,60% of impactions were palatal by 1 to 4 mm,40% buccal by 0 to 4 mm.41 .3% of the impacted canines were without root resorption of adjacent incisor,36.5% with slight,1 4.3% with moderate and 7.9% with severe root resorption of the adjacent inci-sor.Conclusion:
The most frequent location of impacted maxillary canine is palatal and mesial with high incidence of root resorption of adjacent incisor.
