In paralleling technique, receptor position is described as?

• A. Perpendicular to the Tooth
• B. Parallel to the Long Axis of the Tooth
• C. Perpendicular to the Receptor
• D. Diagonally Across the Tooth

Answer: (B)

In paralleling technique, the receptor is positioned parallel to the long axis of the tooth. This alignment lets the X-ray beam be directed perpendicular to both the tooth and the receptor, which minimizes distortion and magnification so the image accurately reflects the tooth’s size and shape. If the receptor were placed perpendicular to the tooth or at an angle to it, or diagonally across, distortion would occur and the resulting image would be less accurate.
