2
what size receptor is recommended for use with the bite-wing technique in the pediatric patient with primary dentition?
0
how is the patient’s head positioned before exposing a bite-wing receptor?
positioned such that the maxillary arch is parallel to the floor and the midsagittal (midline) plane is perpendicular to the floor
what condition is detected by the primary use of bite-wing images?
interproximal caries (tooth decay)
what size receptor is used to include all of the posterior teeth in one bite-wing exposure?
2
what type of angulation is determined by the up-and-down movement of the position-indicating device (PID)?
Vertical angulation
what type of angulation is determined by the side to side movement of the PID?
horizontal angulation
when the central ray of the x-ray is not directed through the contact areas of teeth, what is seen on the resulting image?
overlapping
when does a cone-cut result?
if any portion of the receptor should be visible a cone-cut will result
which of the following describes the primary use of the bite-wing radiograph image?
examine the interproximal areas of teeth
which of the following is the correct vertical angulation used with the bite-wing technique and the bite tab?
+10
which of the following describes the relationship of the receptor to maxillary and mandibular teeth in the bite-wing technique?
the receptor and teeth are parallel to each other
which of the following about receptor placement is correct?
anterior bite-wing may be placed vertically
posterior bite-wing may be placed horizontally
posterior bite-wing may be placed vertically
which of the following about the exposure sequence for a CMRS that includes periapical and bite-wing exposures is incorrect?
