What is the recommended technique for minimizing radiation exposure during intraoral radiography?

The recommended technique for minimizing radiation exposure during intraoral radiography is the paralleling technique. This approach allows for the central ray of the radiographic beam to be perpendicular to both the film and the long axis of the tooth. As a result, it helps to achieve minimal distortion and reduces the need for retakes due to improper positioning.

The paralleling technique also results in more accurate images that require less radiation because the beam is directed straight onto the film or sensor, making it more efficient. By ensuring that the film and the tooth are as parallel as possible, this technique maximizes the effectiveness of the radiation and minimizes unnecessary exposure to both patients and operators.

The use of simple and direct geometric relationships in the paralleling technique makes it a preferred method in dental radiography, ultimately enhancing patient safety by adhering to the principles of radiation protection.
