What are four properties of area specific curets
- Each curet is designed for adaptation to specific area
- Paired working ends
- Face of the blade is offset at an angle of approximately 70 degrees in relation to the lower shank
- Cutting edge is continuous around the face (toe).
-
a universal curet is different from an area-specific instrument in that it has ______ cutting edges
parallel
-
In an area specific curet the face is _____ in relation to the lower shank
tilted
-
In an area specific curet the lower cutting edge is automatically at a ________ to the tooth surface when the lower shank is ______
-
An Area-Specific Curet is a periodontal instrument used to remove _______ deposits from the crowns and roots of the tooth
light calculus
-
A Universal Curet is a periodontal instrument used to remove ______ calculus deposits from the crowns and roots of the teeth
small- and medium-sized
-
In a universal curet the face of the working-end is ______ to the lower shank
perpendicular
-
In a universal curet positioning the lower shank parallel to the tooth surface creates an __________ of 90-degrees
incorrect face-to-tooth surface angulation
-
In a universal curet correct angulation is achieved by ______
tilting the lower shank to 60 80 degrees toward the tooth surface
-
What is the Insertion & Activation of the Instrument subgingival for area specific curets
- 1. Close blade to “0°” at the line angle
- 2. Maintain a light grasp and explore with the terminal ⅓ of the instrument to locate deposit
- 3. Adapt terminal ⅓ of the instrument
- 4. Apply either horizontal, vertical and/or oblique stroke
-
What are the two characteristics of Calculus Removal Stroke
- Brief, tiny, biting stroke used to snap a calculus deposit from tooth
- Moderate pressure is applied against the tooth during this brief stroke
-
What are the three directions of strokes and describe them
- Vertical
- -parallel to the long axis of the tooth, up and down movement
- Horizontal
- -less control, more apt to injure
- Oblique
- -diagonal across surface
-
Instrumentation Technique for Subgingival Scaling
- insert to the base of the pocket, stay sub, if calculus is present move over it to reach the base of the pocket
- Insert at 0-40 degrees angulation
-
What are the benefits of scaling
- 1. Interrupt progression of disease
- 2.Reduce bacterial count.
- shift from predominance of gram - to gram+
- 3. Promote tissue healing
- 4. Increase plaque removal by patient - by motivation, get the patient to make a commitment to their oral health
-
Radiographs are used to view
- 1.Roots
- 2.Furcations
- 3.Bone level
- 4.Overhangs
- 5.Deficient margins
