|
Four parts of dental instruments
|
Handle
Shank Terminal Shank Working End |
|
|
Used to measure DEPTH of Gingival Sulcus. Has MM markings- insert into GS to probe and measure depth
|
PERIODONTAL PROBE
|
|
|
HOOK/ PIG TAIL end: Used to examine tooth surface to look for irregularities
|
EXPLORERS
|
|
|
HAS 2 SHARP SIDES and a sharp tip, supragingivally-may damage gingive so USED ON CROWN SURFACE ONLY for scaling calculus, Has a hook shape; 2 diff kinds
|
SCALER
|
|
|
TWO DIFFERENT TYPES OF SCALERS
|
SICKLE SCALER- most common
MORRIS SCALER- smaller teeth |
|
|
HAS 2 SHARP SIDES AND ROUND/ CURVED TOE/ TIP; used to remove calculus BOTH supragingivally and subgingivally
|
CURETTE
|
|
|
POINT OF THE CURETTE
|
TOE
|
|
|
TWO TYPES OF CURETTES
|
UNIVERSAL
GRACEY |
|
|
COMMON DENTAL EXTRACTION INSTRUMENT
|
DENTAL ELEVATORS
|
|
|
REFLECT INSTRUMENTS IN LIGHT TO SEE SHARPNESS IF _______, THEY WILL REFLECT
|
DULL
|
|
|
ULTRASONIC SCALERS convert _______/_______ energy into MECHANICAL VIBRATION- (energy from power, to sound wave- into vibration
|
ELECTRICAL/ PNEUMONIC
|
|
|
HOLDS THE SCALER LIKE A _______; LIGHTLY NOT TIGHTLY
|
PENCIL
|
|
|
HOW MANY CYCLES PER SECOND DO SCALERS RUN
|
6,000- 45,000 CYCLES PER SECOND
|
|
|
SPEND NO MORE THAN _______ SECONDS ON EACH TOOTH
|
7 SECONDS
|
|
|
TYPE OF ULTRASONIC SCALER; used metal strips/ stacks; runs in narrow motion; lower amplitudes cause less damage to tooth
|
MAGNETOSTRICTIVE
|
|
|
TYPE OF ULTRASONIC SCALER; USES CRYSTALS in the hand piece for vibration; WIDE back and forth action; MOST COMMON***
|
PIEZOELECTRIC
|
|
|
TYPE OF ULTRASONIC TIP; flat, moves from side to side; above GUMLINE ONLY
|
BEAVER
|
|
|
TYPE OF ULTRASONIC TIP; moves up and down; (wood pecker) ; goes below gums
|
PERIO PROBE
|
|
|
TYPE OF ULTRASONIC TIP; same as perio probe, but has 2 tips; goes below gums
|
FURCATION
|
|
|
HIGH WATER?
LOW WATER? |
HIGH- subgingival
LOW- supragingival |
|
|
DENTAL UNIT- polishing/drilling
- less expensive - operate at lower speed - convenient |
ELECTRICAL DENTAL UNIT
|
|
|
DENTAL UNIT-polishing/drilling
- pumps directly into dental unit or tank for slower release - higher torque than electrical - needs to be OILED after use - refrain from CONDENSATION |
AIR DENTAL UNIT
|
|
|
DRILLING HANDPIECE
- Used for polishing/scaling - high torque/ slow speed - slow speed burs |
LOW SPEED HANDPIECE
|
|
|
DRILLING HANDPIECE
- used for CUTTING teeth for extractions; high revelutions per minute; remove and replace burs immediately |
HIGH SPEED HANDPIECE
|
|
|
NORMAL SULCUS DEPTH FOR DOG
|
1-4 MM
|
|
|
NORMAL SULCUS DEPTH FOR CATS
|
0.5-1 MM
|
|
|
BURRS ARE CONSIDERED ____ AND SHOULD BE DISCARDED AS SUCH
|
SHARPS
|
|
|
TYPE OF POWER SCALER; ELLIPTIC MOTION, less likely to cause heat related damage to teeth than ULTRASONIC SCALER; compressed air has a cooling effect
|
SONIC SCALERS
|
|
|
TYPE OF POWER SCALER; DISCOURAGED- can easily damage tooth; burrs must be replaced often
|
ROTARY SCALERS
|
|
|
THE ABILITY TO OVERCOME RESISTANCE TO MOVEMENT
|
TORQUE
|
