According to the American Association of Oral and Maxillofacial Radiology, how often should an x-ray machine be tested?

• A. Annually
• B. Biannually
• C. Quarterly
• D. Monthly

Answer: (A)

Regular quality assurance checks for dental x-ray units focus on keeping exposure accurate, image quality high, and patient safety intact. The AAOMR recommends that a qualified service technician perform a comprehensive performance evaluation of the machine once a year. This annual testing verifies calibration of exposure factors (like kVp and timer), beam alignment, output reproducibility, and overall performance against established specifications. Daily and monthly checks done by the operator support this process but don’t replace the formal annual evaluation. Testing more frequently (monthly or quarterly) isn’t required by AAOMR guidelines and would be unnecessary for most practices, while biannual testing isn’t the standard interval.
