The processing of dental radiological films is constantly evolving technologically, and is having less and less impact on the environment. However, there are places that use manual development, where chemical solutions are needed for the process. For this reason, it is essential to know how all the procedures work correctly, and to properly dispose of the waste generated in order to have as little impact on the environment as possible. The aim of this book is to inform, raise awareness and help professionals and students about the processes and procedures that exist in dental practices and clinics that use a manual process for developing intraoral radiographic examinations.
