Radiographic TechniqueCâu 47 / 100
The dentist orders a posterior bitewing survey on an adult with all posterior teeth present and closed contacts. How many images are typically taken?
a.One image centered on the midline
b.Two images, one per arch
c.Four images, premolar and molar on each side
d.Twelve images covering every posterior tooth individually
Giải thích
A standard adult posterior bitewing survey consists of four images: a premolar and a molar view on each side, which together show interproximal surfaces and crestal bone. A single midline image cannot open posterior contacts. One image per arch is not how bitewings work, since each bitewing records both arches, and twelve images would deliver unnecessary radiation.
