Name three common radiographic artifact types and how to prevent them.

Name three common radiographic artifact types and how to prevent them.

• A. Motion blur (stabilize patient, shorten exposure time), fogging from stray light or chemical residues in the darkroom (control lighting, proper storage), sensor bending or damage (handle gently, barrier sleeves).
• B. Motion blur only
• C. Fogging only
• D. Sensor bending only

Answer: (A)

The main idea here is recognizing the kinds of radiographic artifacts that commonly appear in dental imaging and how to prevent them to keep images diagnostic. Three frequent issues are motion blur, fogging, and sensor damage from bending. Motion blur happens when the patient moves during exposure, or when the image receptor isn’t kept steady. The result is a blurred, smeared look that obscures fine details. Preventing this relies on keeping the patient still and the receptor securely positioned. Use stabilizing aids like bite blocks or rests, give clear instructions, and opt for the shortest practical exposure time with appropriate technique to minimize the chance of movement. Fogging arises from stray light leaking into the darkroom or from chemical residues in processing, which elevates overall density and reduces image contrast. To prevent this, control lighting in the processing area with a proper safelight and filters, store film and sensors in light-tight containers, and maintain clean, fresh processing solutions. Proper handling and timely processing also help keep fogging at bay. Sensor bending or damage is a result of improper handling or placing the receptor under stress, leading to warped images or distortion. Prevention centers on gentle handling and correct equipment use. Always support and protect the sensor with barrier sleeves, avoid sharp bends, and use proper positioning devices to keep the receptor aligned and secure during imaging. Other choices that mention only one artifact type don’t cover the range needed for this question, since the goal is naming several common artifacts and how to prevent them.
