A safelight with a red filter (GBX2) can be used for which types of films?

The use of a safelight with a red filter, such as the GBX2, is beneficial for both intraoral and extraoral films because it is designed to minimize the exposure of photographic film to white light while allowing the light sensitive to the film’s specific wavelengths to remain unaffected.

Intraoral films, which are commonly used for capturing images of the teeth and surrounding structures, are typically more sensitive to blue and green light. The red filter helps to protect these films from fogging during processing, as red light does not disturb the latent image on these films.

Similarly, extraoral films, which include panoramic and cephalometric radiographs, are also compatible with the use of red safelights. These films are designed to be less sensitive to the longer wavelengths of light emitted by the red filter, ensuring that they can be handled safely in low-light conditions without compromising the quality of the images.

Thus, the effectiveness of the red-filted safelight in protecting both intraoral and extraoral films from undesired exposure supports the conclusion that it can be used for both types of films.
