G 21 Flashcards
Maxillary lateral incisor
Palatal groove
Mandibular canine
Deep linear root concavity on proximal surface
Mesial and distal surfaces
Mandibular molar
Wide shallow root concavity on mesial surface
Maxillary first premolar
Deep concavity
Proximal surface
Mandibular molar
Facial surface
Deep depression on root trunk and furcation
Maxillary molar
Concavity from furcation to CEJ
Proximal surface
Mandibular first molar buccal
CEJ to furcation length
Mandibular first molar lingual
CEJ to furcation length
3mm
4mm
Maxillary first premolar
mesial distal
CEJ to furcation length
M 7mm
D 7mm
Maxillary first molar
Buccal mesial distal
B 4mm (boys drool… shortest length)
M 7mm (MJ can jump the highest…longest length)
D 5mm (Diaper duty, 5 kids max)
Tip direction when exploring
How many mm of constant contact
Maxillary upward
Mandibular downward
2mm constant contact with tooth
Most effective manner to position explorer for max 1st premolar. What strokes?
Tip up and horizontal strokes
Direction to explore a concavity
M to D
What instrument is recd to instrument roots of multi rooted teeth ?
Mini area specific gracey curet
Treat each root branch as a single rooted tooth?
Yes distal to mesial
Which instrument is furcation area cleaned by?
Mesial gracey
(Possible board question)
What strokes are used to remove deposits from root concavities and depressions
____ strokes are not effective bc the working end “spans across” root concavity, missing the deposit
Horizontal
Vertical not effective
Can the gracey 11 be used for horizontal strokes?
No just vertical
What position for gracey 12? Toe, fulcrum
Toe down , fulcrum down
Is the correct working end to make a vertical stroke on the mesial surface the same working end to make a horizontal stroke on that same surface ?
NO
Distal surfaces
G13 used for vertical what is used for horizontal?
Mesial surfaces
If G11 used for vertical strokes what is used for horizontal
G 14
G12
Is the same working end used to make vertical and horizontal strokes on FACIAL AND LINGUAL?
Ex. G 12 on both f and l
Yes
The standard fulcrum places the least amount of strain on clinicians fingers and should not be replaced by advanced techniques
T or F
True
When should advanced fulcrums be used ?
Narrow deep perio pockets (distal 3rd molar )
Intraoral fulcrum with an altered point of contact between middle and ring fingers in grasp
NOT same as split fulcrum where ring finger does not touch middle finger
Point of contact is lower against middle finger
Modified Intraoral Fulcrum
Intraoral finger rest in which the finger rest is established on opposite side of arch from the treatment area
Ex: clinician fulcrums on left posteriors while working on right posterior teeth
Cross Arch
Intraoral fulcrum established on opposite arch from tx area
Ex. Fulcrum on mand teeth while working on max
(Deep pockets or hard to reach area)
Opposite Arch
Intraoral fulcrum in which finger of non dominant hand serves as resting point for dominant hand
(Possibly mand anterior for bigger sized pt)
Finger on Finger
Extra oral fulcrums are grasped farther from working end
Yes
Extraoral
Finger of non dominant hand used to concentrate lateral pressure against shank of instrument
-Right handed use left index finger to apply pressure
-Lateral pressure pushed working end forward against the distal/mesial surface
Finger Assist
Extraoral fulcrum “palm out”
Vertical and oblique strokes
This is used to assist in
Maxillary right posterior distal and mesial surfaces
Extraoral fulcrum
Vertical strokes
Can be used for
Max anteriors
Cross arch fulcrum
Working end toe up
Short horizontal strokes
Max mesial root concavities
Mandibular anterior facial surfaces
Finger assist
Palm down
