What is the benefit of using round collimators versus rectangular collimators?

• A. Round collimators are less expensive
• B. Rectangular collimators reduce patient exposure more effectively
• C. Round collimators provide clearer images
• D. Rectangular collimators are easier to handle

Answer: (B)

The primary benefit of using rectangular collimators is their ability to reduce patient exposure more effectively compared to round collimators. Rectangular collimators align more closely with the shape of the typical dental x-ray image receptor, which helps in limiting the area of the patient's face that is exposed to radiation. This precise collimation minimizes unnecessary radiation exposure to surrounding tissues, thus enhancing safety protocols in dental radiography. It allows for a more targeted beam that captures the necessary diagnostic information while protecting the patient from excess radiation. While round collimators may have advantages in terms of cost or handling, these aspects do not outweigh the significant benefit that rectangular collimators offer in terms of reducing radiation exposure, making them the preferred choice in many dental practices.
