Area Specific Anterior Flashcards
How are site specific curets similar to universal curets?
Rounded back
Rounded toe
Semicircular cross section
What are the unique features of site specific curets?
The cutting edges are curved
Universal curet has parallel cutting edges.
How is lower shank and face related in site specific curets?
Face is tilted in relation to the lower shank causing one cutting edge to be lower than the other on each working-end. This is very different to sickle scalers and unversal curets which are 90 degrees..
Which edge is used for calculus removal with site specific curets if their face is angled?
The lower cutting edge only
What is the lower cutting edge called? How is it angled relative to the tooth?
The working cutting edge. It is angled at a 70-degree angle to the tooth surface when the lower shank is parallel
What is the higher cutting edge called? What is its purpose?
The non-working cutting edge. This design feature angles the cutting edge away from the wall of the pocket making it protect soft tissue.
How can the lower edge be identified?
1) Hold instrument so that you are looking directly at the toe
2) Raise or lower the instrument handle until the shank is perpendicular to the floor
3) Look closely at the workign end. One cutting end is lower that the other.
4) The lower edge is used for instrumentation and is the only edge is sharpened.
How should the site specific instrument be tilted relative to the tooth?
The instrument face tilts toward the tooth surface. Face is partially hidden from view.
Where should the working end of site-specific curets be applied relative to the anterior teeth?
One end on the midline to the mesial and the other to the distal. This occurs both facially and distally.
What are the steps to calculus removal in anterior teeth?
Step 1: Place working end in get ready zone near midline of the tooth
Step 2: Insert the curet with the face hugging the tooth surface. Adapt the toe-third. Lock toe-third against the tooth surface.
Step 3: Work across the facial surface
Step 4: Roll the instrument handle as you approach the mesiofacial line angle to maintain adaptation.
Step 5: Work at least halfway across the mesial surface
