DANB Radiation Health and Safety (RHS) Practice Exam

The preferred film size for small children in radiographic assessments is typically?

1. Size 1

2. Size 2

3. Size 3

4. Size 4

The correct answer is: Size 1

In radiographic assessments for small children, size 1 film is preferred primarily because of its appropriate dimensions that fit the smaller oral cavity of pediatric patients. Smaller films ensure that the entire area of interest can be captured without the need for excessive manipulation or discomfort for the child. Using a larger film can lead to difficulty in positioning and increase the likelihood of motion artifacts, as young patients may find it challenging to stay still during the exposure. The smaller size also allows for better exposure control and more focused images, which are crucial when assessing the developing dentition in young patients. This consideration of patient comfort and image clarity makes size 1 the optimal choice for radiographic examinations in pediatric dentistry.
