33
When scaling the angle of the universal curets should be positioned what degree angle to the terminal shank?
90 degree
34
Moving the hoe in the indirect and horizontal manner can cause injury to the
epithelium tissue of the oral cavity.
35
When sharpening Gracey Curets you should hold the sharpening stone\_\_\_\_\_\_\_\_\_\_ to the floor.
perpendicular
36
The Gracey curet has only _______ cutting edge?
one
37
When sharpening Gracey Curets adjust the angle of the stone to more obtuse at about _____ to _____ degrees.
10;20 The angle of the blade's face towards the sharpening stone may be 100 to 110 degrees
38
To maintain the exceptional curvature of the Gracey curet, track the instrument's
contour while sharpening
39
To sharpen the curet blade's face, apply a cone-shaped sharpening stone toward the
curet blade's face in a slight back-and-forth stroke manner.
40
How many strokes should you perform while sharpening the face of the blade?
4 to 6 strokes
41
To estimate the sharpness of the utilized appliance use the
acrylic stick test
42
To protect the curet's toe from getting a cuspate look sharpen the curet's blade completely from
its shank end to its toe. Sharpen all around the toe to maintain its sharp form
43
After finishing the first blade of the universal curet, move to the ________ end and sharpen it using the same principles.
opposite
44
A sharp curet has a fine line at the cutting edge that will not reflect light. T/F
True
45
A dull cutting edge is like a small surface and reflects light as shown. T/F
True
46
Over time, the steam autoclave may dry out an Arkansas stone and lead to chipping or breakage. T/F
True
47
Dry Stone Advantage
The problems related to maintaining a sterile stone and preventing contamination when oil, tap water, or a lubricant is applied are eliminated.
48
A dry stone :sharpens the cutting edge without
nicks in the blade; nicks can be created from particles of metal suspended in a lubricant.
49
A dry stone allows the stone to be completely sterilized without the problem of interference by the
oil left in and on the stone.
50
Water on Stone is used not only for lubrication of ceramic stone, but they may also be used
dry
51
Oil lubrication is recommended with certain quarried stones such as the
Arkansas stone to prevent drying out.
52
Instruments are autoclaved before sharpening, and the stone and instruments are sterilized again after nonsterile
lubricant is used.
53
The lubricant can facilitate the movement of the instrument blade over the stone to prevent
scratching of the stone.
54
Benefits of lubricating a sharpening stone
- Suspend the metallic particles removed during sharpening. - Help to prevent clogging of the pores of the stone (glazing) .
55
The objectives during sharpening are twofold:
▶▶ To produce a sharp cutting edge. ▶▶ To preserve the original shape of the instrument.
56
Instrument shape is also known as
contour
57
The contour of a curet toe is
a smooth, continuous curvature with no points or flat edges.
58
When instruments become grossly dulled, recontouring
wastes the instrument.
59
Restoring original contour to a grossly dull instrument often leaves a blade that is
not functional and therefore useless.
60
Tests for Instrument Sharpness
- Visual or Glare Test - Plastic test stick
61
A solid, consistent bevel results from:
* Instrument and stone positioned at the correct angle. * Movement occurring in a single plane.
62
Irregular bevel is revealed by:
• Breaks in the fine line of the blade edge. • Varying facets indicating the improper stone placement/movement.
63
Newly sharpened instruments are finished by carefully inspecting the edges for a clean consistent bevel with no particles or "wire edge" remaining. T/F
True
64
How is the wire edge produced during sharpening?
- metal particles removed during grinding remain attached to the edge of the instrument and create the wire edge
65
By sharpening into, toward, or against the cutting edge, the production of a wire edge is minimized. T/F
True
66
A two-step sharpening procedure is used for
Universal Curets
67
A three-step sharpening procedure is used.
Area specific Curets
68
Diamond-coated files are not sharpened. T/F
True
69
Two or three passes with the tanged file are usually sufficient to bring each edge back to sharpness. T/F
True
70
When sharpening the Hoe scaler rounded corners help to prevent
laceration of soft tissue or grooving of tooth surface.
71
When sharpening a hoe scaler the hoe needs to be adapted to the surface of a stationary flat stone at the original bevel of _____ degrees?
45
72
To round the sharp corners of the hoe scaler, a flat stone is rubbed over the instrument with a gentle
rolling motion. The sharp corners of a chisel are rounded in the same way.
73
Use ammonia, gasoline, or kerosene when stone becomes
discolored
74
If the stone becomes "glazed" by metal particles ground into the surface, rub the stone over
emery paper placed on a flat, solid surface.
75
Care of the Tanged File
- Corrodes easily, wipe it with isopropyl alcohol soaked gauze - Manufacturer's directions
76
INSTRUMENT SHARPENING:
The process of grinding away metal between two surfaces to remove a rounded junction- without changing the original shape of the instrument
77
CUTTING EDGE:
A line where two surfaces meet at an angle- has length but no thickness when sharp
78
HONING:
Also means sharpening, but is often used to refer to the removal of the wire edge that is raised onto the face of the blade during sharpening
79
BEVEL:
The inclination one line makes with another when they are not at right angles
80
What are the four factors that determine the level of an instrument sharpness?
- patient load - frequency of use - degree of patient difficulty - procedure to be used with instrument
81
