15th millimeter
C. University of Michigan “O” probe: with William markings at 1, 2, 3, 5, 7, 8, 9 and 10 millimeters
D. Michigan “O” probe: with markings at 3, 6, and 8 millimeters.
E. WHO Probe: which has 0.5 mm ball at the tip and mm markings at 3.5, 8.5 and 11.5 mm and
color coding from 3.5 to 5.5

 Nabers probe: for furcation detection it has color coded markings at 3, 6, 9 and 12 mm
2. Explorers

A. #17
B. # 23
C. EXD 11-12
D. #3
E. # 3 CH pigtail
3. Scaling and curettage instruments
A. Sickle scalers
 Have a flat surface and two cutting edges that converge in a sharply pointed tip.
 Primarily it is used to remove supragingival calculus.
 It’s used with a pull stroke.
 Sickle scalers with anterior shank are designed for anterior teeth up to the premolars.
 Sickle scalers with contra-angled shank are designed for posterior teeth.

B. Curettes
 For deep subgingival calculus, root planning, altered Cementum and soft tissue lining of the
pocket
 The basic shapes of curettes are spoon shaped blade with cutting edges on both sides and
rounded tip.

Basic shape of curettes

I. Universal curettes: have cutting edges that maybe inserted in many areas of the dentition.
 When seen in cross-section from the tip, the face of the blade is at a
900 angle to the lower shank.

a. Universal curette A. Columbia #4R-4L


b. Gracey curette B. Younger-Good #7-8, McCall’s #17-18, Indiana University #17-
18
II. Area Specific Curettes: Gracey curettes are the best example of this group
 They are best for subgingival scaling and root planning because they
provide the best adaptation to complex root anatomies.
Gracey Curettes #s-6, #7-8, #11-12, #13-14

Double ended Gracey Curettes are paired like this

Gracey #1-2 and 3-4: Anterior teeth


Gracey #5-6: Anterior teeth and premolars
Gracey #7-8 and 9-10: Posterior teeth: facial and lingual
Gracey #11-12: Posterior teeth: mesial
Gracey #13-14: Posterior teeth: distal

C. Hoe Scaler
 Used for ledge or rings of calculus. The blade is bent at a 990 angle, the cutting edge is
formed by the junction of the flattened terminal surfaces with the inner aspects of the
blade.

D. File Scalers
 Have a series of blades on the base. Their primary function is to crush large deposits of
tenacious calculus.
E. Chisel Scalers
 For proximal surfaces. It is a double ended instrument with a curved shank at
one end and a straight shank at the other. It is placed from the facial side. The instrument
is activated with a pushing motion.
