FPI 11 instrumentation strokes
test questions already graded
A+
instrumentation stroke
the act of moving the working end of a periodontal instrument against the
tooth surface
junctional epithelium
soft epithelial tissue that forms the base of a gingival sulcus or
periodontal pocket
How should vertical strokes be made?
In a coronal direction away from the soft tissue base of the sulcus or
periodontal pocket
Where are vertical strokes used on anterior teeth?
Facial, lingual, and proximal surfaces
Where are vertical strokes primarily used on posterior teeth?
Medial and distal surfaces
What are oblique strokes?
Strokes made in a diagonal coronal direction away from the soft tissue
base of the sulcus or periodontal pocket.
Where are oblique strokes commonly used?
On the facial and lingual surfaces of posterior teeth.
When are horizontal strokes used in dental hygiene?
Around line angles, in furcation areas, and in deep pockets that are too
narrow for vertical or oblique strokes.
Why is it important to note when using horizontal strokes?
The working-end should not come in contact with the junctional
epithelium.
What are multidirectional strokes?
Combined use of all three stroke directions.
, How are multidirectional strokes used in plaque biofilm removal?
The clinician covers the root surface using one stroke direction followed
by a second different stroke direction and finally uses the third stroke
direction.
Why is the multidirectional technique important?
It assures biofilm is removed from every square millimeter of the root
surface.
What is an assessment stroke?
A type of instrumentation stroke used to locate calculus deposits or other
tooth surface irregularities hidden beneath the gingival margin
How are assessment strokes performed during calculus removal?
With a curet to locate calculus deposits, characterized by fingers relaxed
in modified pen grasp, feather-light strokes against the tooth surface, and
longer strokes compared to calculus removal strokes
What is a calculus removal stroke?
A type of instrumentation stroke used to remove calculus deposits from
the tooth with firm pressure of the cutting edge against the tooth surface.
How is a calculus removal stroke characterized?
By a very short, controlled, biting stroke made with firm pressure of the
cutting edge against the tooth surface.
What is the role of the fulcrum finger in a calculus removal stroke?
To support the hand and instrument during a stroke by pressing it down
against the tooth.
What is the purpose of the assessment stroke in calculus removal?
To determine if the calculus deposit has been completely removed by
using a feather-light stroke after each removal stroke.
What is root surface debridement stroke?
A type of instrumentation stroke used to remove residual calculus
deposits, plaque biofilm, and byproducts from root surfaces exposed due
to gingival recession or within deep periodontal pockets.
How is root debridement stroke characterized?
It is characterized by a shaving stroke made with moderate pressure with
the cutting edge against the tooth cementum, a stroke that is slightly
longer than a calculus removal stroke.
