<prompt> The best method to screen a 3-year-old with a sound dentition and open proximal contacts would be:No radiographic assessment.Bitewing RadiographsIntraoral periapical radiographOcclusal radiographs  <response>: The American Dental Association ADA, the American Academy for Pediatric Dentistry AAPD, the European Academy for Pediatric Dentistry EAPD, and other organizations have published criteria that are meant to guide the dental professional in decision-making regarding appropriate radiographic imaging Table 2-5. These guidelines clearly state that if the patient cannot cope with the procedure, one should attempt other strategies to handle the situation. The guidelines all acknowledge that, in some cases, radiographs are not possible, in which case, one should balance the benefit against the risk even more carefully. Sometimes it is better to postpone the radiographic exposure until the patient is older or better conditioned. The guidelines also clearly state that if there are no clinical signs of pathology, the need for a radiographic assessment is up to the professionals judgment, and that these decisions have to be made on an individual patient basis. Radiographs are never to be used for economic and screening reasons since they involve a potential health risk for the patient.
