The majority of problems in radiography can be traced to improper film pro-cessing procedures. There are many types of dental X-rays, but bitewing, periapical, and panoramic radiographs are the most common ones. The goal in dental radiology is to use techniques that require the least amount ofradiation exposure to produce imageswith the right amount of density and contrast.To better understand density and contrast, let'slook at some dental radiographs. Their right side will correspond to your left. CBCT in dentistry is the major single contributor of diagnostic radiation, and recent publications have expressed concerns regarding the safety of this imaging procedure in children.11 A 2012 advisory statement from the ADA Council on Scientific Affairs states: As with other radiographic modalities, CBCT imaging should be used only after a review of the patients health and imaging history and the completion of a thorough clinical examination, and Dental practitioners should prescribe CBCT imaging only when they expect that the diagnostic yield will benefit patient care, enhance patient safety or improve clinical outcomes significantly.4 Recommendations from regulatory agencies such as the FDA18provide guidance regarding strategies to maximize safety and efficacy.

This can be achieved by moving the film away from the crowns of the teeth. To gain the most useful image of a canine tooth, the operator must ensure that the mesial of the canine is separated from the lateral incisor, or that the central beam goes through the embrasure between the canine and lateral (Figure 9).
