5. Q5. Which of the following is false • Bone density is different in crestal region and apical region • Higher the no. of Hounsfield units , lower the density. • Periapical radiographs are also reliable sources to measure bone density • Single-tooth or a two-teeth partially edentulous span almost always have D2 bone. • 1 and 2 • 2 and 3 • 3 and 4 • NONE
