Adaptation
Is the positioning of the first 1 to 2 mm of the working-ends lateral surface in contact with the tooth
What are the 3 imaginary sections of the working-end
Leading third
Middle third
Heel third
What is the leading third of a curet
Toe-third
Leading third of a sickle
Tip third
What is not adapted to the tooth surface
The heel third
Angulation
Is the relation between the face of the working end and the tooth surface
Study page 249
Insertion
Is the action of moving the working-end beneath the gingival margin into the sulcus or periodontal pocket
It’s going to between 0 and 40 degrees very important to remember the numbers
Tactile sensitivity
Middle finger and shank are most important in tactile sensitivity. Feel vibrations indicating irregularities through quivers from the explorer
Adaptation
How the explorer is touching the tooth
Which part touches the tooth
Only the leading third or the lateral surface are touching the tooth
What is an assessment stroke
Is to detect deposits and tooth irregularities requires light controlled strokes with light pressure against the working end, it is longer stroke Light Long stroke Overlapping Many/overlapping stroke
What are the three types of strokes
Assessment stroke
Calculus
Where should the functional shank be for correct working end in posterior
Right over the tooth
What are the 4 types of stoke directions
Vertical, oblique, horizontal, multidirectional. Stroke
Where do you usually you an oblique direction stroke
Mainly on lingual facial surfaces on posterior
Study page 249
When would you usually use a vertical direction stroke
On the anterior.
Study page 249
When would you use vertical stroke on posteriors
When you are working in distal and mesial. Interproximal
Study page 249
When would you use a horizontal direction stroke
Primarily on the line angle.
Biggest reason clinician don’t find calculus on the line angle is because they are not using horizontal direction
On page 249
What are all the explorers used for caries detection
Cow horn, pigtail, straight, or Shepard
Page 290
Sulcus
Space between tooth and gum use this term when it’s healthy if it’s not healthy you will use the term periodontal pocket
What is the angulation for calculus removal
60 and 80 very important to remember
The most ideal position 70 to 80
What are the two types of motion activation
Wrist motion activation, digital motion activation
Wrist activation
Rotating he hand and wrist as a unit to create and instrument stroke
Wrist motion activation
Moving the instrument by flexing the thumb index and middle fingers used primarily with ultrasonic.
Not recommended bad ergonomics
