A. Upper incisor
B. Upper canine
C. Upper premolar
D. Upper molar
The correct answer is D. Upper molar.
- Elevators should not be used to remove the palatal root of an upper molar.
- The buccal wall of socket does not form satisfactory fulcrum and can be crushed by the elevating force.
- Furthermore, there is always the danger of forcing the root into antrum.
- The palatal root must be seen clearly, which usually implies the removal of both buccal roots and if necessary some surrounding bone, which can be done with a bur.
- Gentle dislocation with a narrow coupland chisel or rotation with upper root forceps should deliver the root.
