Both storage phosphor (SP) plates and charge-coupled devices (CCDs) must be wrapped in a protective sleeve before being placed in the patients mouth, and CCDs require a sensor holder. This will help the patient be more compliant as the procedure continues.2.

Look at the large card and try to recall what is on the other side. The identification dot on the film is always placed in the slot of the film holder. Premolar Bitewing Image Using BW Tabs Film: Center horizontally Front edge includes the distal of the canine Place front edge of the film across to the opposite arch anteriors Positioning Indicator Device (PID): The middle of PID is placed at the occlusal surface Central ray directed between first and second premolars . Chronic radiation exposure occurs when __________ doses of radiation are received over a _________ time period. c. fish and eggs The molar image should show the distal of the second premolar and completely include the terminal molars on each side of the patient's mouth. Insufficient vertical angulation causes foreshortening. The premolar image should display the distal surfaces of the maxillary and mandibular canines. Incorrect Vertical Angulation: positioning the central ray so that the vertical angulation is too steep (greater than the optimal +10 degrees) provides an image that is foreshortened, or too short in the vertical dimension.

Prevent Technique Errors - Dimensions of Dental Hygiene | Magazine Con: Unable to see apex. Seat the patient, in an upright position in the dental chair. Fixer cutoff will result in a straight, black border. Incorrect positioning of the film in relation to the teeth produces a BW image that doesnt provide a clear view of some areas of the teeth that are required. more adverse systemic effects than if small, localized areas of the body mount the films in the order of the teeth. Incorrect settings may produce a film that has improper density (too light or dark) or poor contrast (too much or too little) making the interpretation of the image on the film difficult. films exposed, processed, and mounted should be kept in the patients Figure 26 - Bitewing image did not capture Maxillary margins or bone.
