To select the correct working end for use on the distal surface of a molar tooth, the clinician should do which of the following?
a. Tilt the lower shank and the face of the curet slightly away from the distal surface b. Place the lower shank so that it goes "down and around" the facial surface of the tooth. c. Observe the relationship between the distal surface of the molar and the lower shank of the instrument, the lower shank should be perpendicular to the distal surface. d. Observe the relationship between the distal surface of the molar and the lower shank of the instrument; the lower shank should be parallel to the distal surface. |
