1
Q

What is gingivitis?

A

Gingivitis results in reversilble damage to the ginginva

There is no damage to periodontal tissue

Q

What are the 4 possible levels of the gingival margins?

A

Margin at CEJ

Margin in health covers 1, 2, 3 mm

Margin significantly covers CEJ

Margin significantly apical to CEJ

Q

Where is the normal gingival margin in health?

A

The natural position of the gingival margin in health

The normal level is slightly above the CEJ

Q

What situation can arise when the gingival margin is too high?

A

The gingival margin significantly covers the CEJ and this is commonly seen in gingivitis

Q

How is recession of the gingiva measured?

A

Measure and record amount of gingival recession. Measure the distance from the gingival margin to the CEJ

Q

What else should be measured to measure the gingival margin position?*

A

It is important to determine how far the gingival margin is coronal to its normal level slightly above the CEJ

Q

How is *

A

Position the tip of the probe at a 45 degree angle to the tooth

Slowly move the probe tip along the tooth until you detect the CEJ

Record the distance between gingival margin and CEJ

Q

What is the difference between probing depth and pocket depth?

A

Normal sulcus is 1 2 or 3 mm anything deeper is a pocket.

Q

What must be done when there is bone loss?

A

If there is bone loss you need to know how much bone has been lost and this cannot be obtained from a radiograph

Q

Is probing depth enough to make a diagnosis?

A

A probing depth reading alone is not enough for a diagnosis.

17
Q

What other sign besides measurement is important to know more about pathology? What does it tell us besides about the periodontal health?

A

Bleeding on probing means there is inflammation.

Bleeding on probing is an indication of potential bone loss. If there is no bleeding there is no bone loss

18
Q

What else must we know besides the bone support of the tooth?

A

In addition to bone support what we really need to know is the location of the periodontal attachment system of the root. Attachment loss is common in people with periodontal disease hence the deeper pockets.

19
Q

What does the periodontal attachment system consist of? (revision)

A

Junctional epithelium

Gingival fibers

Periodontal ligament fibers

Alveolar bone

20
Q

What is clinical attachment level?

A

The estimated positionof the structures that support the tooth as measured witha periodontal probe

21
Q

What are the gingival margin level readins and probing depth readings used for?

A

The gingival margin level readings and probing depth readings are used to calculate the clinical attachment level of a tooth

22
Q

What is the function of the junctional epithelium?

A

Attaches gingiva to the tooth

23
Q

What happens during periodontitis?

A

The periodontal attachment system is destroyed by periodontitis

24
Q

What is a furcation?*

A

The place on a multirooted tooth where the root trunk splits into separate roots

25
Q

What is furcation bone loss?

A

Loss of alveolar bone between the roots

26
Q

What is a furcation probe?

A

A probe that can be put into the furcation to identify it.

It is not straight

27
Q

What should be noted about maxillary first premolar root number?

A

Maxillary first premolars MAY be bifurcated

28
Q

What is a class 1 *

A

Probe tip can enter partially into the furcation extends about one third of the tooth but no able to pass through completely

29
Q

What is tooth mobility and what causes it?

A

Tooth mobility is the loosening of the tooth and is a result of loss of bone and periodontal tissue

30
Q

WHat is horizontal mobility?

A

Horizontal mobility is labial lingual

31
Q

What are the classes of tooth mobility?

A

Class 1 = Up to 1mm of horiznotal movement

Class 2 = Greater than 1 mm in a facial lingual direction

Class 3 =greater than 1mm in a facial lingual and vertical as well
