Universal Curets Posterior Flashcards
Which cutting edge of a universal is closer to the handle?
Inner is closer
Outer is further
Where is the inner cutting edge used?
Distal surfaces
Where is the outer cutting edge used?
Facial, lingual, and mesial surfaces
Memory aid for inner vs outer cutting edge:
I start IN on the distal surface then move out to the facial and mesial surfaces
What angle should the universal curet be with the tooth?
70 - 80 degree face-to-tooth angulation
What angle is the face of the working end compared to the lower end? What does this mean?
90 degrees which means positioning the lower shank parallel to the tooth surface creates an incorrect face-to-tooth surface angulation of 90 degrees
How should the lower shank be in a universal curet compared to the tooth?
It should have its lower shank tilted in the direction of the tooth surface
How should universal curet be applied to posterior sextant?
For distal surface use inner edges; half the distal surface is done with one edge and then the instrument is flipped for the other edge.
For the rest of the surfaces the same is done.
What are the steps of using a universal curet for calculus removal from posterior mandibular sextant?
Step 1: Place curet in the get ready zone. Toe of the working end must point towards the distal surface
Step 2: Enter the gingival margin ensuring that face is hugging the tooth surface
Step 3: Establish angulation and lock toe-third to tooth surface. Make strokes around the line angle and halfway across the distal surface
Step 4: Place the working-end in the get ready zone near the line angle of the facial surface (toe points forward)
Step 5: Make sure that the face hugs the tooth surface and gently insert working-end beneath the gingival margin
Step 6: Work across the facial surface, roll the handle as you approach the mesiofacial line angle
What are the steps of using a universal curet for calculus removal from posterior maxillary sextant?
Step 1: Turn toe towards distal surface. Establish 0-degree angulation and insert
Step 2: Establish angulation,, lock the toe third and make strokes around the line angle halfway across the distal surface
Step 3: instrument for the distofacial line angle to the midline of the distal surface
Step 4: Place working end in the get ready zone near the line angle on facial surface. Toe points forward
Step 5: Work across the facial surface and roll the handle as you approach the mesiofacial line angle.
Step 6: Work from the mesiofacial line angle to the midline of the mesial surface
