Q

What are we looking for with the 11/12 explorer

A

Tooth anomlaies
Calculus
Overhangs
Wrong restorations

20
Q

What happens if too much pressure is applied?

A

You feel tooth topography and will continue to take off cementum

21
Q

Why is the explorer thin?

A

To disseminate between tooth and calculus

22
Q

Basic instrumentation of explorer

A

Insertion, angulation, and adaptation is one fluid motion

23
Q

What’s the movement under the gum?

A

Always done w/ motion, follow terminal shank so always adapted

24
Q

What happens if your instruments aren’t sharp?

A

With dull blades comes increased pressure, Not able to remove calculus even though everything else is sound

25
Where does the hypersensitivity come from?
Removing the cementum
26
How do you adapt to the tooth w/ the explorer?
Roll the back of the instrument away from the tooth to maintain adaptation
27
Motion Activation, helps prevent RSD
Handle roll, Wrist knock, Pivot knock
28
Subgingival Assessment w/ 11/12 explorer | Beginning
Adapt 1-2mm of working end at tooth surface and slide under gingival margin, down to JE or base keeping 1-2mm in constant contact w/ root surface
29
Subgingival Assessment w/ 11/12 | Activation
Active stroke w/ wrist activation to move tip forward, apical and oblique w/ overlapping strokes Control stoke w/ 2-3mm to remain in sulcus and maintain 1-2 mm working end in contact
30
Subgingival Assessment w/ 11/12 | End
1-2mm tip will always lead stroke while in contact driven by wrist activation Exploring proximal will require strokes to cover more than 1/2 the interproximal
31
Vertical assessment stroke | Anterior
used on F, L and proximal surface
32
Vertical assessment stoke | Posterior
Used primarily on mesial and distal surfaces
33
Oblique assessment stroke
Strokes across F or B surface | Down, up and over stroke produced at a slight angle
34
Horizontal Stroke
Strokes made in a perpendicular direction to long axis of tooth
35
11/12 Exploring anterior teeth
Need to flip handle to do either surfaces towards or away for each aspect, Sequence follows 1/2 of surfaces towards then surfaces away Overlap at midline each time you enter
36
What does the explorer do to the anterior teeth?
Wrap around each of the surface
37
Sequence of exploring | Posterior
Adapt explorer to mesial to find correct working end Start at distal Enter at DLA and continue w/ vertical and oblique strokes into col area Reenter at DLA and move forward w/ vertical and oblique stokes to mesial col
38
Type 0 Health
No clinical changes from health in gingival color, form, position and surface appearance. No bleeding upon probing. No connective tissue loss. No bone loss, 0-3mm present
39
Type 1 Gingivitis
Gingival inflammation characterized clinically by changes in color, gingival form position and surface appearance. Bleeding upon gentle probing. No connective tissue attachement loss. No bone loss. 0-3 mm sulci present
40
Type 2 Early Periodontitis
Progression of gingival inflammation into deeper perio structures and bone crest. Bleeding upon gentle probing. Slight connective tissue lost. Slight bone loss. 3-4 mm sulci present. (CSN will use this type to classify cases w/ >3mm resulting from inflammation)
41
Type 3 Moderate Periodontitis
More advanced stage of type 2 w/ increased destruction of perio structures. Bleeding upon gentle proving. Moderate connective tissue attachment loss. Moderate bone loss. Possible mobility. Possible furcation involvement. 4-6mm pocket present. Refer to specialist
42
Type 4 Advanced Periodontitis
More advances of type 3 w/ advanced destruction of perio structures.Bleeding upon gentle probing. Advanced connective tissue attachment loss. Advanced bone loss. Mobility. Furcation involvement 7+ pockets. Refer
43
A Light
Grainy and/or light calculus in localized areas in posterior teeth and/or light to moderate calculus on anterior (Type 1 or 2)
44
B Moderate
Moderate deposits readily discernable-auditory click and visible jump of explorer. Minimum of 6 posterior deposits and at least 2 must be molar proximals
45
C Difficult
Heavy deposits that cover the majority of the surface line angle to line angle and may conjoin w/ addition surfaces. Minimum of 9 posterior deposits at least 4 must be molar proximals
46
D Perio maintenance
Light deposits, patient may have had fairly routine supportive care, however presents w/ need for more extensive care that previously provided (Type 3 or 4)
