G. Mod. 16 Technique Essentials: Subgingival Calculus Removal

Question 1

Subgingival deposits are located

Answer 1

Calculus located apical to gingival margin (below)

Question 2

Distribution of sub deposits may be ____ or _____ through mouth

Answer 2

Localized or generalized

Question 3

Common deposits on root surface (3)

Answer 3

1- apical to CEJ
2- line angles
3- within furcation areas and root concavities

Question 4

What is always covering a calculus deposit

Plays significant role in contributing to periodontal disease

Answer 4

Layer of living bacterial plaque biofilm

Question 5

Insertion
Act of…

Answer 5

Act of gently sliding working end of explorer or curet beneath gingival margin into gingival sulcus or perio pocket

Question 6

Angulation during insertion

____ angle

Answer 6

0-40*

Closed angle (face closed against tooth as much as possible)

Question 7

Steps to prepare for insertion

Establishing…
Selecting…
Preparing by…

Answer 7

Establishing secure finger rest near tooth instrumented

Selecting correct working end of double ended

Preparing for insertion by placing working end on crown in “get ready zone”

Question 8

Periodontal instrumentation

Removal or disruption of

Reestablish

Answer 8

Removal or disruption of plaque biofilm its byproducts and biofilm retentive calclus

Reestablish perio health and restore balance between bacterial flora and hosts immune response

Question 9

Rationale for Subgingival instrumentation
AICIP

Answer 9

1- arrest progress of disease by removing plaque biofilms and plaque retentive calculus deposits
2- induce positive changes in sub bacterial flora (count and content)
3-create good environment. assist in maintaining tissue health and gingival tissue to heal thus eliminating inflammation in periodontium
4- increase effective pt care remove difficult to clean areas
5- prevent recurrence

Question 10

Nonresponsive disease site

Areas in periodontium that show (3)
Despite of
Performed _ month earlier
Identified by

Answer 10

Areas in periodontium that show
-deeper probing depth
-continuing loss of attachment or
-clinical signs of inflammation
in spite of sub instrumentation performed 1 month earlier

Identified by redness, bleeding

Question 11

Multi directional strokes

Pattern created is

Answer 11

V, o, h overlapping series

Crosshatch

Question 12

Angulation of:

Assessment strokes

Calculus removing

Ideal calc removal

Answer 12

Angulation 40*

45-90*

70-80*

Question 13

Root debridement strokes
Removes (3)
Face to root angle

Answer 13

Remove biofilm, calc, surface irregularities from root

Face to root angle 60-70*

Question 14

Steps in calculus removal stroke

Answer 14

1. Assess- stroke away from JE until calculus deposit is encountered
2. Cup- cup calculus deposit with face of curet
3. Stroke- create calculus removal stroke by locking toe third against tooth surface to correct 70-80* Angulation while making short biting strokes away from base of pocket
