Prognosis Flashcards
Twin studies found what risk factor for periodontitis?
greater IL-1
3 things prognosis tells you? 2 things needed to predict?
course, duration, outcome
pathogenesis, risk factors
5 categories of prognosis?
good fair poor questionable hopeless
good prognosis means? fair? poor questionable hopeless
good attachment, control of etiologic factors
fair - attachment loss, furcation I, can maintain hygeine
poor - moderate attachment loss, furcation I/II, difficult to maintain hygiene
questionable - severe attachment loss, class II/III furcations, 2+ mobility, Not accessible to maintenance care
Hopeless - inadequate attachment, extraction necessary
Outcomes of prognosis for.. good fair poor questionable hopeless
good - 90% stable
fair & poor - stable or improved 85%
questionable - improve 80%, 20% teeth lost
hopeless - 40% teeth lost
Which teeth are predicted most accurately?
single root
Which teeth maintained worse than projected?
third molars
Which prognosis most accurate?
only good
4 clinical factors to consider for prognosis?
compliance
disease severity
plaque control
age
4 systemic/environment factors to consider for prognosis?
smoking
systemic disease
genetics
stress
What root anatomical factors give poorer prognosis?
short tapered roots
concavities
proximity
What Crown anatomical factors give poorer prognosis?
cervical enamel projections
enamel pearls
Bifurcation ridges
dev. grooves
What gingival factors = poorer prognosis?
furcation
mobility
Chronic perio prognosis
good with control, poor with furcation mobility or noncomplicance
Aggressive perio prognosis
good wtih early tx/dx
