What is the primary color of the tube side of the dental film packet?

The primary color of the tube side of the dental film packet is solid white. This choice is correct because the solid white side is specifically designed to face the x-ray tube during the exposure process. The color helps dental professionals easily identify the correct orientation for optimal results. The white side also often reflects light, enhancing film sensitivity and image quality.

The other choices provide color characteristics that do not accurately describe the tube side of the film packet. Color-coded might imply multiple colors for organization but does not refer to the specific side in question. Translucent or black do not apply to the tube side, which must be solid white to ensure proper function during radiographic procedures.
