National Dental Assisting Examining Board © 2001 – 2025 National Dental Assisting Examining Board 14 Evaluation Form: Procedure As described previously, skill evaluation forms are divided into two sections – “Procedure” and “Professional Practice”. This section describes what candidates should know about the “Procedure” criteria for performing the skills, in the context of manikins as patients at the CPE. It addresses how the CPE will unfold using manikins. Exposing Digital Radiographic Images All sites use a combination thyroid collar/lead apron. Radiographic images will be exposed on a Dexter using the paralleling technique for periapical images and the RINN bitewing equipment or tab for the bitewing, with phosphor storage plates (PSPs). Information specific to opening and closing the Dexter and activating the exposure button will be provided. Candidates will NOT be given instruction or a demonstration on how to assemble the RINN XCP equipment for image exposure. Candidates must assemble their own RINN XCP paralleling equipment and place the PSPs into the biteblock for the periapical and bitewing images. If the candidate chooses to use the tab instead of the RINN XCP bitewing holder for the bitewing, they must place their own bitewing tab on the plate.
