Diagnostic Imaging for Root Resorption Risk

Imaging Recommendations

• Level I radiographic investigations, such as panoramic radiography, are not adequate for identification and characterization of external root resorption, with a detection rate of only 5.31% compared to 22.88% detected by CBCT 1, 2, 3
• Orthopantomography should be the first diagnostic examination for suspected impaction, but CBCT should be reserved for cases where level I investigations cannot provide adequate information 1, 2
• CBCT is essential for assessing relationships between third molars and critical structures, including the mandibular canal and maxillary sinus floor, and should be indicated when direct contact between second and third molars is observed on panoramic radiographs 1, 3
