Which statement accurately describes CBCT imaging compared with conventional CT?

CBCT in dental imaging is designed to give clear, detailed images of hard tissues—teeth and surrounding bone—while keeping radiation exposure relatively low compared with conventional medical CT. The cone-beam setup and targeted field of view let you capture high-resolution 3D data of bone structures with less dose, which is ideal for implants, endodontics, and assessing bone loss. Soft tissue contrast is not as good with CBCT, but that’s acceptable for dental purposes where hard tissue detail is the priority. This is why the statement describing CBCT as providing good hard tissue detail with typically lower radiation dose for dental use is the best description. The other statements don’t fit: CBCT generally uses less radiation than conventional CT, it does not have lower resolution for bone, and it can image bone.
