1

What is a basic exam set-up composed of

A mouth mirror, a regular probe, furcation probe, and explorers

2

3 parts of the mirror

Handle
Shank
Working end

3

Purposes and uses of the mouth mirror

Indirect vision, indirect illumination, transillumination, retraction

4

Indirect vision

Needed in surfaces where direct vision is not possible (EX. distals of posterior teeth and lingual anteriors)

5

Indirect illumination

Reflect light from dental light to an area in the oral cavity

6

Transillumination

A reflection of light through the teeth

7

Retraction

Mirror used to protect or prevent interference by the cheeks, tongue, or lips

8

Grasp and rest (mirror)

Use modified pen grasp with finger rest wherever possible
To provide stability and control
To assist in retraction

9

How to maintain clear visions with mirrors

Warm mirror w/ water, rub buccal muscosa to coat mirror w/ saliva, and request pt. to breathe through nose to prevent condensation of moisture on mirror.
Discard scratched mirrors

10

Why would you use air during a dental procedure

To improve and facilitate exam procedures

11

How does air improve and facilitate exam procedures

Make thorough, more accurate examination
Dry supra gingival calculus to facilitate exploring and scaling. Deposits may not be visible until dried. Dried calculus will appear chalky and there is contast in color
Deflect free gingiva tissue for observation into the subginigval area
Make identification of area of demineralization and caries easier
Recognize location and condition of restorations

12

Prepare teeth and gingiva for cetain procedures (air)

Application of sealants
Make impression for study cast
Apply topical anesthetic

13

Precautions when using air

Avoid sharp blasts of air on sensitive cervical areas of teeth or open carious lesions. Can use gauze to dry instead to avoid pt. discomfort
Avoid applying directly into pocket. Sub gingival biofilm can be forced into tissue and cause bacteremia

14

Probe

Used in determining diease status of the periodontal tissues

15

Types of probes

Traditional and automated (florida probe)

16

Probe used to

Assess periodontal status for preparation of treatment plan
Make a sulcus and pocket survey
Determine clinical attachment level
Make a mucogingival examination
Make other gingival determinations
Evaluate success and completeness of treatment
Evaluation at maintenance appointments

17

Assess periodontal status for preparation of treatment plan

Classify is it gingivitis or periodontal
Determine if there is bleeding upon probing

18

Difference between ginigvitis and periodontis

Gingivitis is reversible and no bone loss
Periodontis is not reversible and has bone loss

19

Make a sulcus and pocket survey

Examine shape, topography, and dimensions of sulk
Measure and record depths
Evaluate tooth surface pocket wall
Chart calculus location and severity
Record other root surface irregularities

20

Make a mucogingival examination

Detemine relationship to gingival margin, attachhment level, mucogingival junction

21

Make other gingival determinations

Evaluate gingival bleeding on probing, prepare bleeding index
Measure recession
Determine consistency of tissue

22

Evaluate success and completeness of treatment

Evaluate post-treatment tissue response intially and at periodic maintenance exams
Identify signs of continued health

23

Evaluation at maintenance appointments

A re-evaluation with complete probing is needed at each maintenance appointment (every 3 months)

24

Probes have what kind of tips

rounded

25

Straight working end probe

Has smooth rounded end
Calibrated in millimeters

26

Curved working end probes

Nabors probe
For investigation of topography and anatomy of roots in furcation

27

Pocket

A diseased gingival sulcus. The use of a probe is the only accurate dependable, method to evaluate pockets

28

Pocket characteristics

A pocket is measure from the base of the pocket to the gingival margin
The pocket is continuous around the entire tooth
The depth varies around individual tooth
Proximal surfaces are approached by entering from the facial and lingual aspects of the tooth
Anatomic features of the tooth surface influence the direction of probing

29

What stroke do you use when probing and why

Walking stroke because the depth of the sulcus varies around the tooth

30

Factors that influence probing

The general objectives of probing are accuracy and consistency
Recordings are dependable for comparison with future probing
Patient discomfort and trauma must be minimal
