The use of CBCT (Cone Beam Computed Tomography) for internal root resorption is particularly appropriate due to its ability to provide three-dimensional images of dental structures with high precision. This advanced imaging technique allows for a detailed assessment of the root morphology and the extent of resorption, which is crucial for effective diagnosis and treatment planning.

CBCT is uniquely suited for visualizing complex dental issues, as it can isolate specific areas of concern in greater detail than traditional two-dimensional radiographs. This capability is vital when evaluating internal root resorption, where understanding the spatial relationship and the degree of root damage is essential for formulating an appropriate orthodontic or endodontic approach.

Other types of radiographs, while useful in specific circumstances, do not offer the same level of detail or three-dimensional perspective. For instance, a periapical radiograph provides useful information about the roots and surrounding bone but does not deliver the comprehensive views necessary for assessing internal structures. Similarly, panoramic radiographs give a broad overview but lack the resolution needed for detailed analysis of root resorption. Cephalometric radiographs primarily focus on the skeletal framework and dental relationships and are not specifically optimized for root evaluation.

Therefore, CBCT stands out as the preferred option for diagnosing internal
