Question

For a dental radiograph to be diagnostic, how many millimeters must be visible around each tooth root? a. 3 mm b. 2 mm c. 1 mm d. 0 mm

Answer 1

b. 2 mm

Step-by-step explanation:

In order for a dental x-ray to be useful for diagnosis, it's crucial to have enough space around each tooth root visible on the image. This allows the dentist to get a clear picture of the tooth's position and overall health, as well as the surrounding structures. To ensure accurate assessment, at least 2 mm of visibility is necessary. Having less than 2 mm of visibility can cause important details to be missed, which could lead to misdiagnosis or an incomplete evaluation.
