A comparison of various conventional radiographic solutions for localization of impacted tooth / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the reliability of localization of the impacted teeth by assessing various conventional radiographies. Methods:32 patients with impacted teeth were included. The impacted teeth were localized by conventional roentgenographic techniques including panoramic radiography (PR) and linear tomography (LT).Results:Dentomaxillary orthopantomographic solution (PR,LT and PR combined with LT) clearly presented the position of the impacted teeth. Serial cross-section linear tomography also ensured the shape and axis of the impacted teeth captured on the radiograph. The accuracy of the localization was further verified by the surgical exposure in 5 cases. Conclusion:Orthopantomographic assessing can directly and precisely localize the buccal and lingual position of the impacted teeth.
