Comparison of Cone Beam CT and Periapical Film in Diagnosis of Tooth Root Fracture

Abstract

Abstract: Objective: To compare the diagnostic value of cone beam CT (CBCT) and periapical film in tooth root fracture. Methods: Thirty-seven teeth from 35 patients were included in this study whose roots were fracture confirmed after extraction or surgical exploration. All teeth were examined by both CBCT and periapical film. Radiological images were analyzed and compared. Results: Of the 37 fractured teeth, CBCT detected 35 teeth and periapical film detected 16 teeth. Conclusion: The accuracy of CBCT in detection of tooth root fracture was significantly higher than that of periapical film. The CBCT clearly showed the location and type of root fracture. The CBCT held important clinical value in the treatment planning of tooth root fracture.
