Radiology Practice Test

How often should x-rays be taken?

1. As often as the dentist deems necessary

2. Every month

3. Yearly

4. Every 5 years

The correct answer is: As often as the dentist deems necessary

X-rays should not be taken on a regular basis, unless absolutely necessary. The other options suggest taking x-rays too frequently, which can expose the body to unnecessary radiation. A patient's x-ray schedule should be determined by their dentist based on their individual dental health and risk factors. Yearly or every 5 years may be appropriate for some patients, but it is ultimately up to the dentist's discretion.
