What is the consequence of incorrect horizontal angulation in radiographic imaging?

Incorrect horizontal angulation in radiographic imaging primarily leads to overlapping images. When the X-ray beam is not directed horizontally, the resultant image can cause structures in the teeth or bones to overlap. This overlap reduces the clarity of the individual structures being examined, making it difficult to accurately assess conditions such as cavities or periodontal disease. Proper horizontal angulation is crucial to ensure that the X-ray captures each tooth and surrounding anatomy distinctly, allowing for an effective diagnosis.

Other potential consequences of improper techniques in radiographic imaging can include artifact creation or misinterpretation of the images, but the direct result of incorrect horizontal angulation specifically manifests as overlapping images, which is why this option is the most accurate choice in this context.
