Question

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?
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?
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 1

1. Use a size 0 film for bitewings on a 2-year-old — it’s the pediatric size designed to fit small primary dentition and posterior anatomy comfortably.
2. Reassure Mr. Huang that digital sensors are safe and in fact reduce patient radiation exposure (often by 50% or more compared with conventional film), provide instant images, and eliminate chemical processing. They’re solid-state electronic devices with no ionizing emissions beyond the x‑ray beam and also cut down on environmental waste from developer/fixer.
3. Very light films after manual processing most commonly mean underdevelopment — the developer may be exhausted, too cold, overly diluted, or the films were not left in developer long enough. Check developer temperature and concentration, processing time, and replace depleted chemicals to correct the problem.
