perio classification

Question 1

what is the difference between dehiscence and fenestration

Answer 1

for fenestration, the marginal bone is still intact, but for dehiscence the denuded areas extend through the marginal bone

Question 2

what are the classifications of perio health, gingival diseaes and conditions

Answer 2

1. perio health and gingival health
2. gingivitis: dental biofilm induced
3. gingival disease: non dental biofilm induced

Question 3

what are the classification of periodontitis

Answer 3

1. necrotising periodontal disease
2. periodonttis
3. periodontitis as a manifestation of systemic disease

Question 4

what is considered pristine periodontal health

Answer 4

a state free from inflammatory perio disease

1. no bop
2. no attachment loss
3. no PD of more than 3 mm
4. no redness
5. no clinical swelling or edema
6. no pus

Question 5

what is the standard for good clinical perio health on an intact periodontium

Answer 5

no attachment loss, bop less than 10%, PPD 0-3mm

Question 6

what is a stable perio patient? what are closed pockets?

Answer 6

px has BOP less than 10% and closed pockets. no BOP at sites with more than 4mm

Question 7

what are the featureof dental biofilm induced gingivitis

Answer 7

bop 10% or more

no attachment loss

probing depth 0-3mm

gingival redness and edema

radiographic bone loss–> if have, gingivits on a reduced periodontium/ gingival inflammation on a reduced periodontium in a successfully treated perio patient

Question 8

how do u determine whether it is localised or generalised gingivitis

Answer 8

localised- limited to gingiva in relation to a single tooth group or a group of teeth, less tan 30% of sites

generalised- gingiva throughout the mouth- 30% or more of sites

Question 9

what are the categories for severity of gingivitis

Answer 9

mild: papilla or area with a minor change in colour and little change in texture of tissue: less than 10% of sites

moderate: papila and marginal gingiva or area with glazing, redness, edema, enlargement, BOP 10-30% of sites

severe: papila, marginal gingiva and attached gingiva or area with overt redness and edema tendency toward bleeding when touched. >30% of sites

Question 10

what are the primary features of periodontitis

Answer 10

1. loss of perio tissue suport like clincal attachment loss
2. radiographic bone loss
3. presence onf periodontal pocketing
4. gingival bleeding

Question 11

what are the key descriptor elements for diagnosis

Answer 11

1. type
2. extent
3. stage
4. grade
5. relevant risk factors
6. disease status ( is it active? unstable?)

Question 12

what does grading of perio aim to indicate

Answer 12

the rate of perio progression, response to standard therapy and its potential impact on systemic health

Question 13

what is considered stable perio diseaseq

Answer 13

when local and systemic factors are controlled

when periodontitis is sucessfully treated

when min bop less than 1-%

when PPD 4mm or less

lack of progressive destruction

Question 14

when is perio in remission

Answer 14

perio treated but no total resolution

not optimal control of local and systemic factors

BOP 10% or more

PPD 4m or less, no BOP t 4mm sites

lack of progressive destruction
