Question 2

How do we move with probe ?

Answer 2

to the bottom of the pocket and gently moved laterally along the pocket wall.

Question 3

What should we do in probing in 6 points ?

Answer 3

• Teeth number should be recorded
• Total number of Teeth surfaces should be counted
• Brobing in 6 points should be done for all teeth
• Bleeding areas should be identified and recorded
Mesio and disto buccal and buccal lingual the same done at the embrasure

Question 4

How to culculate ?

Answer 4

Total Number of bleeding areas / number of examined surfaces * 100%
70/120 * 100% = 58%

IV degree >60-up to80%
V degree >80-up to 100%

Question 7

How to assess furication ?

Answer 7

probing with Naber’s probe
radiograph of this area

Question 8

What’s F0 and F1 ?

Answer 8

F0- No furcation involvement
F1- probe enters furcation area by 1 mm

Question 9

What’s F2 and F3 ?

Answer 9

• F2-probe enters furcation area by more than 1 mm, reaching the up to half of the crown not exeeding the opposite side of the furcation

• F3-. probe entirely enters furcation area , which is seen in the oral cavity or is covered with gingiva

Question 10

How to measure gingival recession ?

Answer 10

By Perio probe&raquo_space; from the CEJ to the gingival crest.

Question 11

What’s GR risk factors ?

Answer 11

• Aggressive brushing
• Hard brush
• Incorrect technique
• Frequency and duration of brushing • Frequency of brush replacement

Question 12

What’s biological pocket depth ?

Answer 12

distance between the gingival margin and the base of the pocket (the coronal end of the junctional epithelium)

Question 13

What’s probing depth ?

Answer 13

is the distance to which the instrument (probe) penetrates into the pocket.
The depth of penetration depends on:
size of the probe,
force with which it is introduced, direction of penetration,
resistance of the tissues, convexity of the crown.

Question 14

What’s probing technique ?

Answer 14

• . The probe should be inserted
• parallel to the vertical axis of the tooth and
• “walked” circumferentially around each surface of each tooth to detect the areas of deepest penetration

• special attention should be directed to detecting
• the presence of interdental craters and furcation involvements.

Question 15

What should we do to detect an interdental crater ?

Answer 15

the probe should be placed obliquely from both the facial and lingual surfaces so as to explore the deepest point of the pocket located beneath the contact point

Question 16

What’s Pocket depth ?

Answer 16

is the distance between the base of the pocket and the gingival margin

Question 17

What’s CAL ?

Answer 17

distance between the base of the pocket and a fixed point on the crown, such as the cementoenamel junction
In normal cases 0

Question 18

In which cases loss of attachment is zero ?

Answer 18

When the gingival margin is located on the anatomic crown, the level of attachment is determined by subtracting from the depth of the pocket the distance from the gingival margin to the cementoenamel junction.

If both are the same ( equal 2-2=0 )its 0

Question 19

When the loss of attachment equals the pocket depth ?

Answer 19

When the gingival margin coincides with ( on the ) the cementoenamel junction,

Question 20

When loss more than the pocket ?

Answer 20

When the gingival margin is located apical to the cementoenamel junction, the loss of attachment is greater than the pocket depth,

and therefore the distance between the cementoenamel junction and the gingival margin should
be added to the pocket depth

Question 21

How probing participate in bone loss assessment?

Answer 21

1) the height and contour of the facial and lingual bones obscured on the radiograph by the dense roots and
(2) the architecture of the interdental bone.

Transgingival probing, performed after the area is anesthetized, is a more accurate method of evaluation
and provides additional information on bone

Question 22

What’s Intrabony Pocket ?

Answer 22

The bone destructive pattern is vertical transseptal fibers are oblique rather
than horizontal

Question 23

Suprabony pocket ?

Answer 23

Horizontal bone loss

Question 24

How ostroblasts work ?

Answer 24

the synthesis of the bone matrix, which subsequently undergoes calcification.
• Initially, uncalcified matrix, called osteoid, is formed and this is mineralized as a result of deposition of crystals of hydroxyapatite.

Question 25

What’s happen in osteoclasts in Perio disease ?

Answer 25

• Bone destruction in periodontal disease is caused by local factors and systemic factors.
• Bone destruction in periodontal disease is not a process of bone necrosis.
• It involves the activity of the live cells along the viable bone

Question 26

• Local factors of osseous defect ?

Answer 26

• a. Chronic gingival inflammation
• b. Trauma from occlusion
• c. Combination of both

Question 27

What’s systemic factors predispose bone loss in periodontitis ?

Answer 27

• Osteoporosis is a physiologic condition of postmenopausal women, resulting in loss of bone mineral content and microstructural bone changes.

• generalized skeletal disturbances e.g. hyperparathyroidism, leukemia, etc.)

Question 28

What’s the anatomic features affect the bone destructive pattern in periodontal disease ?

Answer 28

1. Thickness, width and crestal angulation of the interdental septa
2. Thickness of facial and lingual alveolar plates
3. The presence of fenestrations and dehiscences

Question 29

What’s Osseous Craters ?

Answer 29

They are concavities in the crest of the interdental bone confined within the facial and lingual walls.
• It is found to make up two-thirds of all mandibular defects, can be
• diagnosed by transgingival probing.

Question 30

Does rdiograph help us in determine or see characteristics of bone in periodontist?

Answer 30

The radiograph does not reveal minor destructive changes in bone

The radiographic image tends to show less severe bone loss than that actually present
The radiograph is an indirect method for determining the amount of bone loss in periodontal disease;

it shows the amount of remaining bone rather than the amount lost.

Question 31

Why most radiographic changes appear in interdental septa ( laminaldura )?

Answer 31

Cause lingual and buccal cortical plates are thick

Question 32

What we assess in radiograph in periodontitis ?

Answer 32

the interdental septa undergo changes that affect appearance of this structure in x ray :

the lamina dura,
crestal radiodensity,
size and shape of the medullary spaces,
height and contour of the bone.

Question 33

What’s interdental septa destruction appearance ?

Answer 33

Horizontal
Vertical
Break Lamina dura continuity
