National Dental Assisting Examining Board © 2001 – 2025 National Dental Assisting Examining Board 15 suction. Candidates must demonstrate their knowledge of removing the excess anti-cariogenic agent after the trays are removed from the mouth, but there is not an expectation that candidates will be able to remove all of the excess fluoride from the plastic teeth. Applying Pit and Fissure Sealant The pit and fissure sealant will be applied to the prescribed tooth using cotton roll isolation. Although the manikin does not salivate, candidates must demonstrate their knowledge of adequate isolation and re-isolation without saliva contamination. Applying Topical Anesthetic On the manikin, the muccobuccal fold is located where the gingival tissues meet the hard plastic. Evaluation Form: Professional Practice This section describes what candidates should know about the “Professional Practice” criteria for performing the skills, in the context of manikins as patients at the CPE. It addresses how the CPE will unfold using manikins. Infection Prevention Candidates will not be required to wash their hands prior to placing their mask and putting on their gloves. No over gloves or barriers will be used to cover equipment. All equipment and supply items are for your manikin (patient). Regardless of the style of uniform/scrubs/lab coat, gloves must be worn in compliance with standard aseptic protocols. Gloves must be over top of long sleeves. Gloves must be worn throughout the prescribed treatment. Glove changes may be requested by the candidate as often as required. Glove changes are off-time. Wrist watches, medical alert bracelets, bracelets, bangles or rings worn at the wrist must be covered with a barrier. Barrier tape will be provided by the site. Masks must be worn throughout the prescribed treatment. Masks must be placed fully covering the nose and mouth at all times. Mask changes may be requested by the candidate as often as required. Mask changes are off-time. All aspects of infection prevention must be adhered to during the prescribed procedure while the timer is running. Before the timer is started or after the timer is stopped, infection prevention is not evaluated. If an instrument or supply item is dropped on the floor, the timer will be stopped while the evaluator replaces it. If any other break in asepsis occurs during the prescribed procedure at any time while the timer is running, it is the responsibility of the candidate to correct the error. If an instrument comes in contact with the candidate’s hair or uniform/scrubs/lab coat, breaking the chain of asepsis, during the prescribed procedure at any time while the timer is running, the candidate must request a new instrument. The timer will be stopped while the correction of the asepsis error takes place. If a new instrument is not requested and the candidate continues to work intra-orally, causing cross contamination, the candidate will receive a “U” grade for the critical criterion “Maintains aseptic technique during the timed procedure” and “Performs the skill safely and with care,” resulting in failure of the skill.
