In-Class Assignment (Critical Thinking
)
1. Jason Marks is a 2-year-old patient in your office, and you are going to take bitewing radiographs on him. What size film do you think you will need?
Answer:
In the office you'll be using a Intraoral film. A child thats under 3 years old will use a size #0 flim. Intraoral film consists of a semiflexible acetate film base that is coated on both sides with an emulsion of silver bromide, silver halide, and silver iodide that is sensitive to radiation.
2. Your dental office has recently transitioned to digital radiography. Mr. Huang, who has not been in the office for almost 3 years, begins to ask you questions about the safety of digital imaging and wants to know why you are using sensors instead of film. How would you respond?
Answer:
I would explain to Mr. Huang that digital radiography eliminates chemical processing and hazardous wastes from chemicals and lead foil. The Images can be electronically transferred to other healthcare providers without loss of the original image quality. I also would explain that it a modern and new way to take x-rays.
3. Nancy is a new dental assistant in your office, and she just finished manually processing some dental radiographs. When you look at the films, you notice that they are very light. You exposed the films, so you are certain that the exposure factors were correct. What could have gone wrong?
Answer: Nancy could have put them in developer for a short time. Even if i continue to do the rest of the steps, they were no longer fixable or didn’t have any solution on them.
