What is the function of the raised button on a radiograph?

The raised button on a radiograph serves a specific function related to the organization and identification of the radiographs, which is mounting. When radiographs are taken, they need to be properly mounted for analysis and interpretation. The raised button often indicates the orientation or specific area on the radiograph, helping to identify which image belongs to which patient or which specific view of the anatomy is represented. This feature aids the dental professional in efficiently sorting and mounting the films for viewing, thus streamlining the workflow during patient assessment.

In contrast, determining film speed relates to how quickly a film reacts to radiation, while processing involves the chemical steps required to develop the film after exposure. Drying pertains to the final step where the films are dried after processing. None of these functions directly relate to the raised button's primary purpose of aiding in the organization and mounting of radiographs.
