periodontal pocket and pattern of bone loss

Question 1

deepening of the gingival sulcus may occur by what 3 ways?

Answer 1

coronal movement of gingival margin, apical displacement of gingival attachment, or combination of both.

Question 2

define periodontal pocket

Answer 2

bottom of sulcus to gingival margin

Question 3

periodontal pocket is classified as…..

Answer 3

gingival pocket or periodontal pocket( infrabony pocket and suprabony pocket)

Question 4

whats a gingival pocket?

Answer 4

formed by enlargement without destruction of underlying periodontal tissues. Sulcus is deepened because increased bulk of gingiva

Question 5

whats a periodontal pocket?

Answer 5

formed via apical migration of attachment apparatus, Includes destruction of supporting perio tissues, either suprabony of infrabony

Question 6

suprabony pocket

Answer 6

aka supracrestal or supraalveolar pockets, bottom of pocket is above alveolar crest

Question 7

what are some clinical features of periodontal disease?

Answer 7

mobility, diastemea, localized pain, perio probing depth, BOP, bluish red, thickened marginal gingiva

Question 8

what kind of probe shoud you use on an implant?

Answer 8

a plastic one

Question 9

how many sites are there to check while probing each tooth?

Answer 9

6

Question 10

while probing what motions should you use.

Answer 10

use little bouncing motions. Its called walking stroke.

Question 11

why walk the probe?

Answer 11

to make sure to record the deepest reading per site.

Question 12

T/F, probe should be parallel to the long axis of the tooth while walking ?

Answer 12

ture

Question 13

while probing the interproximals you should use an angle. what is this angle?

Answer 13

no specific angle , each site is a little different.

Question 14

perio probing should be ___ of force?

Answer 14

.75 N, BOARD ? IF YOU USE THE SAME AMOUNT OF FORCE ON HEALTHY AND DISEASED POCKETS, THE PROBE PENETRATES MORE ON DISEASED POCKETS

Question 15

first 4 steps of pathogenesis of diseased pockets.

Answer 15

1. bacterial plaque
2. hosts immuno-inflammatory response triggered
3. release of cytokines by PMNs, fibroblasts, monocytes and others

4.degeneration of surrounding connective tissue apical to junctional epitheliuim

Question 16

next 5 steps of pathogenesis of diseased pockets

Answer 16

5. apical cells of JE proliferate along root
6. coronal end of JE detaches from rooth surface
7. apical shift of junctional epithelium
8. pocket depth increases

Question 17

soft tissue

Answer 17

Vasoproliferation, vasodilation and engorged blood vessels, length of JE reduced, leukocytes increase and edema occurs

Question 18

what happens to the tooth morphology during perio disease

Answer 18

calculus covers cementum, plaque attachement, zone of unattached plaqu, zone of attachement of the junctional epithelium to the tooth, zone of semidestroyed connective tissue fibers.

Question 19

Horizontal bone loss

Answer 19

most common, bone reduces in height, bone margin remains perpendicular to tooth surface
( horizontal bone loss results up to 50% loss of interdental septal bone)

Question 20

what 2 problems must you remember with someone who had horizontal bone loss?

Answer 20

mobility and functional stability.

Question 21

vertical/angular bone defects

Answer 21

occur in oblique direction, leave a hollowed-out trough in the bone alongside the root, base of defect is apical to surrounding bone, mostly seen accompanying infrabony pockets.

Question 22

infrabony defects

Answer 22

these are classified on the basis of remaining osseuos walls, ( either 1,2,3 walled defects,

Question 23

which infrabony defect most frequently occurs?

Answer 23

three- walled.

Question 24

when being flapped and bone grafted, which infrabony defect has the most success rate?

Answer 24

3, ( the higher number of walls the better the success)

Question 25

when a 3 walled defect wraps around the tooth , what is it reffered to as?

Answer 25

cercumferential defect.
