What is the role of a collimator in dental radiography?

• A. To increase radiation intensity
• B. To focus the X-ray beam
• C. To limit the size of the X-ray beam and reduce patient exposure
• D. To provide a shield for the operator

Answer: (C)

The role of a collimator in dental radiography is primarily to limit the size of the X-ray beam and reduce patient exposure. This component is crucial for enhancing the safety of both patients and dental practitioners. By restricting the area that is irradiated, collimators help in minimizing unnecessary radiation exposure to surrounding tissues. This is important not only for reducing the potential risks associated with radiation, such as cancer or tissue damage, but also for improving the quality of the diagnostic images by preventing scatter radiation that can obscure details. Collimators achieve this by adjusting the shape and size of the X-ray beam, ensuring that it conforms closely to the area of interest. This concentrated beam not only cuts down on excess radiation but also enhances the clarity and quality of the images produced. By ensuring that the X-ray beam is as precise as possible, collimators play a vital role in maintaining safety standards in dental practices.
