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
Q

Where does the hypersensitivity come from?

A

Removing the cementum

26
Q

How do you adapt to the tooth w/ the explorer?

A

Roll the back of the instrument away from the tooth to maintain adaptation

27
Q

Motion Activation, helps prevent RSD

A

Handle roll, Wrist knock, Pivot knock

28
Q

Subgingival Assessment w/ 11/12 explorer

Beginning

A

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
Q

Subgingival Assessment w/ 11/12

Activation

A

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
Q

Subgingival Assessment w/ 11/12

End

A

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
Q

Vertical assessment stroke

Anterior

A

used on F, L and proximal surface

32
Q

Vertical assessment stoke

Posterior

A

Used primarily on mesial and distal surfaces

33
Q

Oblique assessment stroke

A

Strokes across F or B surface

Down, up and over stroke produced at a slight angle

34
Q

Horizontal Stroke

A

Strokes made in a perpendicular direction to long axis of tooth

35
Q

11/12 Exploring anterior teeth

A

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
Q

What does the explorer do to the anterior teeth?

A

Wrap around each of the surface

37
Q

Sequence of exploring

Posterior

A

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
Q

Type 0 Health

A

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
Q

Type 1 Gingivitis

A

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
Q

Type 2 Early Periodontitis

A

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
Q

Type 3 Moderate Periodontitis

A

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
Q

Type 4 Advanced Periodontitis

A

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
Q

A Light

A

Grainy and/or light calculus in localized areas in posterior teeth and/or light to moderate calculus on anterior (Type 1 or 2)

44
Q

B Moderate

A

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
Q

C Difficult

A

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
Q

D Perio maintenance

A

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)
