Which device assists in the positioning of the position indicator device (PID)?

• A. Beam Alignment Device
• B. Radiopaque
• C. Chronic Radiation Exposure
• D. Bitewing

Answer: (A)

Positioning the X-ray beam accurately is crucial for getting a clear image and avoiding repeats. The device that assists in aligning the position indicator device is the beam alignment device. It helps ensure the X-ray beam is centered on the tooth and travels along the same path as the PID, which improves image quality and reduces the chance of cone cuts or wasted radiation. By guiding both vertical and horizontal angulation, it makes the exposure safer and more consistent. The other options don’t serve this role. Radiopaque describes materials that block X-rays and appear white on images, not a tool for aiming the PID. Chronic radiation exposure is a risk concept, not a positioning aid. Bitewing is a type of dental X-ray image, not a device used to position the PID.
