Instrument Design & Identification
What size calculus is the 17/18 used to remove?
Small/medium size
Cell that provide the 1st line of defense
Neutrophils/PMN's
Type of image it produces
How many visits minimum should a patient with an obturator have?
Three
What is advanced instrumentation?
advanced protective scaling techniques that use both hands while scaling
Is this instrument used supra or subgingivally?
Both. supra and subgingivally
bone consuming cells that destroy alveolar bone
Osteoclasts
Main advantage of CAM/CAD
Faster turnaround time
What clock position is used for maxillary arch posterior region?
8-9 o'clock
What are two characteristics of the 17/18?
A rounded back, rounded toe
Two cutting edges per working end
A semicircular cross-section
How to measure CAL
pocket depth + recession = CAL
What does CAM/CAD stand for
Computer-aided design
Computer-aided manufacturing
What technique (stroke) is used for the lingual aspect of reinforcement?
Vertical pull strokes
What is the degree of the face to the lower shank?
the face is at 90-degree angle
2 major risk factors associated with periodontal disease
Smoking and Diabetes
List 2 disadvantages for CAM/CAD dentistry
Cost of equipment
Special training required
Software compatibility issues
Maintenance required
Describe how to hold the instrument for reinforcement
Instrument needs to bisect & rest between thumb and forefinger (stability/power)
Thumb needs to be slightly convex
Both hands must work together as a unit to establish more power
Where can this instrument be used?
Can be applied both anterior and posterior teeth, works universally.
3 main bacteria associated with periodontitis
P. gingivalis, T. forsythia, T. denticola
Most important factor when prepping the tooth
Conserving enamel
Name 5 advantages of reinforcement
Enhances the balance of both hands
Increases control of instrument blade
Increases lateral pressure
Improves scaling efficiency
Increases power
Helps prevent musculoskeletal injuries
