Purpose:
To compare the clinic value between dentomaxillary pantomography and periapical radiographs in localization of the impacted teeth.
Methods:
43 impacted teeth were localized with both dentomaxillary pantomography technique and periapical radiographs with horizontal tube shift which is clinically widely used. And a comparison between the two methods was carried out using Chi square test.
Results:
Both dentomaxillary pantomography and periapical radiographs with horizontal tube shift can relatively precisely demonstrate the position of the impacted teeth. The percentage of the cases which the image and the result of surgery was consistent in the two methods was 93.02% and 95.35% (P>0.05) respectively. There was no statistical difference between the two groups.
Conclusions:
Dentomaxillary pantomography can precisely localize the impacted teeth.
