What tooth surface(s) is not treated by the Gracey 1/2 for an anterior tooth?

Marta is examining the working-end of a treatment instrument. The instrument has a rounded toe, rounded back, and one cutting edge that is lower than the other lateral surface. What design classification is this instrument?

What tooth surface(s) is not treated by the Gracey 11/12 or Gracey 15/16 curet?

Place the following statements in the appropriate sequential order for the placement of the mirror for #26 DF.  In your answer, please put a comma between the numbers. Place the fulcrum for the mirror to retract the lip Place the light in a perpendicular position The operator sits in the 8:00 position for a right-handed clinician or 12:00 for a left-handed clinician Direct patients head towards the operator Ask patient to open

Assume your instrument set contains the following selection of area-specific curets. Which area-specific curet should not be used on the facial surface of a maxillary molar?

The more posterior the tooth, the more angulated a shank must be. The mesial surface of a molar is less accessible than the distal surface.

What is the operator’s chair position for tooth #7DF (answer question according to your dominant hand)?

Answer the question based on your dominant hand. The mirror fulcrum for tooth #29 MF is placed approximately around the area of: #5/6 for a right-handed operator or #5/6 for a left-handed operator. The operator can select the 11/12 curet and/or the 7/8 curet to remove the calculus on #29 MF supra?

The modified pen grasp for the mirror helps the clinician provide stability and control. The clinician can use a rubber band and/or a ball to strengthen the muscles of the hand and to reduce operator fatigue.

The universal and the area-specific curets have two cutting edges.  More than one Gracey curet would be needed to instrument the posterior teeth.
