perio tx planning etc

Question 1

what is taken into account when diagnosing perio?

Answer 1

severity and extent of disease/pockets
pts age
local irritants

Question 2

what categorises a stable periodontium?

Answer 2

no BOP/inflammation

pt has low plaque scores

Question 3

what categorises gingivitis?

Answer 3

no LOA
redness/swelling/ BOP
false pocket

Question 4

what categorises periodontitis?

Answer 4

LOA
BOP
true pocketing
bone loss radiographically
irriversible tissue damage

Question 5

what are some prognostic factors of perio disease?

Answer 5

systemic health
genetic predisposition
aeitology - e.g aggressive = reduced prognosis
age related to LOA
smoking status
attitude vs cooperation

Question 6

what are some local prognostic factors?

Answer 6

plaque 
organisms present
pocket depth
location and distripution 
severity of LOA
furcations
restorative condition
endo disease
root morphology
calculus

Question 7

what is the order of perio tx planning?

Answer 7

initial exam and pain relief
initial cause related therapy
re examination and definitive tx plan
definitive tx - perio consultation/chemical adjunct/repeat tx
maintenance

Question 8

what is non surgical periodontal therapy?

Answer 8

OHI
supragingival
subgingival scaling
rev in 6-8 weeks

Question 9

how are deep pockets with no BOP treated?

Answer 9

no RSD because could worsen

shorter recall and evaluate/month

Question 10

how does healing take place?

Answer 10

Long JE
shrinkage of gingivae
tightening of g. cuff

Question 11

what is maintenacne?

Answer 11

pt is periodontally stable
no BOP, ppd under 3mm
recall is shorter dependent on susceptibilty of patient

Question 12

what are types of disease progression?

Answer 12

linear disease vs burst theory

Question 13

what index measures mobility?

Answer 13

millers index

Question 14

what is a pocket?

Answer 14

pathogenically deepened gingival crevice with ulcerated epithelial lining, JE and diseased root surface - calc, endotoxins, microorganisms

Question 15

what is the aim of NS tx?

Answer 15

create an environment biollogically compatible with healing

through - decon of root surface, elimination of plaque biofilm, removal of bulk calc

Question 16

what does RSD eliminate?

Answer 16

endotoxins
plaque biofilm
subg calc
outermost necrotic cementum

Question 17

why is calculus indirectly affected?

Answer 17

coating of plaque
impedes good oh
absorbs endotoxins
impedes probing depth

Question 18

what is cause related therapy?

Answer 18

HPT
smoking cessation
remove plaque retentive factors
suprag and subg scaling

Question 19

frequency of ultrasonic?

Answer 19

18-50kHz

Question 20

types of ultrasonic?

Answer 20

• magnetostrictive - current produces magnetic field and vibration at working tip
• piezolectric - vibration of tip back and forth
• sonic - air driven handpiece. less efficent bc slower vibration

Question 21

reasons for RSD failure?

Answer 21

medical history
initial cause of tx
scaling and rsd
non scaling procedures
smoking

Question 22

tx plan order for restorative tx?

Answer 22

emergency care
prevention
stabilise active disease
restorative
maintenance
