A patient is seated in your dental chair, and during the examination prior to choosing a size of sensor; you see a shallow palate, and narrow maxilla and mandibular areas. You decide to use a #1 sensor. When taking bitewings with a #1 sensor, you cannot get under a deep crown with bitewings. However, the patient’s mouth will not accommodate a #2 film. It is best to take an extra periapical film of the tooth with the deep crown, so the dentist can give a diagnostic examination.

Bitewing radiograph: Parallel technique where the film shows the upper and lower teeth in occlusion.
Blurred image: Decreased detail on a film due to patient, film, or x-ray source movement.
Collimator cutoff: Not centering the x-ray beam on the film, causing …show more content…
The long axis of the molars should be parallel with the long axis of the film. The center of the film should be aligned with the second molar, and be sure to position the film in the palate to include the entire length of the teeth. In the maxillary film, there will not be a superimposition of the zygomatic arch in the paralleling technique because the arch is too high to be seen on the film. After taking the film, be sure to put it in a lead box, as to avoid double-exposed projections.
The size of a pediatric patient’s mouth must be taken in consideration prior to taking radiographs. The child’s age and size of mouth determines the composition of the pediatric FMX. If the paralleling technique will not fully work on a pediatric patient, before using the bisecting angle technique show and tell about the procedure, reassure the patient; demonstrate the behavior and act confident. Sometime a child will surprise you with their good behavior and resiliency for treatment. Gaining trust is the best way to get the patient at their best
