Universal Curets Anterior Flashcards
What is a universal curet?
A periodontal instrument used to remove small and medium sized calculus deposits from the crowns and roots of teeth. Both supra and subgingivally.
Why is a universal curet “universal”?
Because it can be used on both anterior and posterior teeth.
What are the unique design characteristics of a universal curet?
A rounded back
A rounded toe
2 cutting edges per working end
Semicircular in cross section
The face is perpendicular to the lower shank so the 2 cutting edges are level with one another
How do different designs of universal curets differ?
There are many different designs of universal curets:
Shorter vs longer lower shank + working end
Why would a shorter universal curet be used?
It can only be used within normal sulci or shallow pockets.
Why would a longer curet be used?
For deep pockets
Working end is long so it can also be used for mesial and distal surfaces of molar teeth
Which curets are most ideal for posterior teeth?
Curets with a longer lower shank and longer working-ends
How is a universal curet chosen to be used for anterior teeth?
The lower shank of a universal curet is across the tooth surface; this is a visual clue used to select the correct working-end.
Which cutting edges are used when using universal curets on anterior teeth?
The outer edges
Which edge is the outer edge of a universal curet?
the furthest cutting edge from the handle
How should calculus be removed from anterior teeth with a universal curet?
Step 1: From midline of tooth to distal surface
Step 2: Place working end in the get ready zone, toe of working-end points towards the mesial surface.
Step 3: Establish 0 degree angulation with face hugging the tooth surface. Gently insert beneath the gingival margin.
Step 4: Adapt the toe-third to the root surface and instrument from the midline of the facial towards the mesial surface.
Step 5: Roll the instrument handle as you approach the mesiofacial line angle to maintain adaptation.
Step 6: Continue strokes at least halfway across the mesial surface.
What order should everything be prepared?
Me, my patient, my light, my mirror, my grasp, my finger rest, my adaptation.
How should the universal curet look relative to the anterior teeth?
Anterior teeth should go across the facial or lingual surface.
What are the advantages of the complex shank design?
The complex shank design of a universal curet sometimes facilitates access to the lingual root surfaces of mandibular anterior teeth.
