perio tx planning etc Flashcards
what is taken into account when diagnosing perio?
severity and extent of disease/pockets
pts age
local irritants
what categorises a stable periodontium?
no BOP/inflammation
pt has low plaque scores
what categorises gingivitis?
no LOA
redness/swelling/ BOP
false pocket
what categorises periodontitis?
LOA BOP true pocketing bone loss radiographically irriversible tissue damage
what are some prognostic factors of perio disease?
systemic health genetic predisposition aeitology - e.g aggressive = reduced prognosis age related to LOA smoking status attitude vs cooperation
what are some local prognostic factors?
plaque organisms present pocket depth location and distripution severity of LOA furcations restorative condition endo disease root morphology calculus
what is the order of perio tx planning?
initial exam and pain relief initial cause related therapy re examination and definitive tx plan definitive tx - perio consultation/chemical adjunct/repeat tx maintenance
what is non surgical periodontal therapy?
OHI
supragingival
subgingival scaling
rev in 6-8 weeks
how are deep pockets with no BOP treated?
no RSD because could worsen
shorter recall and evaluate/month
how does healing take place?
Long JE
shrinkage of gingivae
tightening of g. cuff
what is maintenacne?
pt is periodontally stable
no BOP, ppd under 3mm
recall is shorter dependent on susceptibilty of patient
what are types of disease progression?
linear disease vs burst theory
what index measures mobility?
millers index
what is a pocket?
pathogenically deepened gingival crevice with ulcerated epithelial lining, JE and diseased root surface - calc, endotoxins, microorganisms
what is the aim of NS tx?
create an environment biollogically compatible with healing
through - decon of root surface, elimination of plaque biofilm, removal of bulk calc
what does RSD eliminate?
endotoxins
plaque biofilm
subg calc
outermost necrotic cementum
why is calculus indirectly affected?
coating of plaque
impedes good oh
absorbs endotoxins
impedes probing depth
what is cause related therapy?
HPT
smoking cessation
remove plaque retentive factors
suprag and subg scaling
frequency of ultrasonic?
18-50kHz
types of ultrasonic?
- 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
reasons for RSD failure?
medical history initial cause of tx scaling and rsd non scaling procedures smoking
tx plan order for restorative tx?
emergency care prevention stabilise active disease restorative maintenance referrals
