Apical radiographs can be challenging to interpret due to the two-dimensional depiction of complicated anatomy that combines [[Bones - Anatomy & Physiology#Organisation of Bone|trabecular (spongy) bone, compact bone]], soft tissue, and air spaces all projected at various angles and configurations. Other confusing lucencies and opacities can be created by the summation effect of superimposed structures, projecting overlying anatomy in a way that makes it appear to be associated with a tooth root or its supporting bone. These can include bony foraminae, bony fissures, bony canals, and trabeculae. Many non-pathological lucencies, opacities, and apparent deviations from normal can be distinguished from true lesions by comparison with a radiograph of the contralateral tooth.
