28
Q

with questionable prognosis there is ________ attachment and bone loss

A

severe (>50%)

29
Q

what kind of furcation involvement is present in questionable prognosis?

A

CL II or III

30
Q

what kind of mobility is present in questionable prognosis?

A

CL II or III

31
Q

what kind of mobility is present in hopeless prognosis?

A

CL III

32
Q

what kind of bone loss is present in hopeless prognosis?

A

severe

33
Q

T/F with a hopeless prognosis it may jeopardize the adjacent tooth

A

true

34
Q

whta kind attachment is present in hopeless prognosis?

A

inadequate attachment to maintain health, comfort, function

35
Q

T/F you can save a tooth with a hopeless prognosis with extreme tx measures

A

False. non-restorable, ext indicated

36
Q

what 3 prognosises were est with reasonable degree of accuracy

A

good, fair, hopeless

37
Q

what prognosises were likely to change and were more unpredictable?

A

poor, questionable

38
Q

what are the big factors assoc with the overall prognosis?

A

disease severity (PD, furcation involvement, mobility, % bone loss)
smoking

39
Q

with individual tooth prognosis what are the influences?

A

same factors as overall prog. plus
local factors
tooth anatomical factors
prosthetic and restorative factors

40
Q

T/f you should determine the individual tooth prognosis first

A

false. overal prognosis first

41
Q

what grades generally lead a good perio prognosises? what are the exceptions?

A

grades A/B
except:
severe perio
non-compliant
pt with systemic disease
these will downgrade to fair/poor

42
Q

molar-incisor pattern perio has a __________ prognosis if treated early with systemic antibiotics and regenerative therapy

A

good

43
Q

generalized Grade C perio has _________ or _________ prognosis

A

poor, questionable
do not respond well to conventional periodontal therapy

44
Q

the _______ the stage and/or grade the ________ the individual and overall prog.

A

higher, poorer

45
Q

with perio as a manifestation of systemic disease it has a ______ or _______ prog

A

poor, questionable

46
Q

w/ necrotizing gingivitis there is a _________ prog

A

good
with recurrent it downgrades prog.

47
Q

what are clinical factors that determine prog?

A

pt age
disease severity
plaque control
pt compliance

48
Q

which has better prog.
tooth A: 8 mm pocket, heavy calc in a 50 yr old pt
tooth B: 8 mm pocket, no calc in a 30 yr old pt

A

A
tooth has a slower rate of progression
tooth b has grade C perio
removal of local factors (calc) can improve the prog of tooth A

49
Q

older pt vs young pt with the same amount of attachment loss. which pt has a better prog?

A

older pt
b/c rate of progression is slower
grade a perio has a better prog than grade c perio

50
Q

what are the big local (tooth related) factors that determine prognosis?

A

probing depth
mobility
furcation involvement
bone loss severity

51
Q

__________% of molars have cervical enamel projections at the furcation

A

17-28%

52
Q

what’s the issue with cervical enamel projections?

A

ct fibers will not attach to enamel
increases susceptibility to pocket formation
increases susceptibility to furcation involvement

53
Q

what’s the issue with the mesial root concavity?

A

difficult access for scaling

54
Q

which tooth is common for mesial root concavity?

A

max 1st premolars

55
Q

what is the percentage of time that the M root of the mand 1st molar has a concavity? for the distal?

A

100%, 99%

56
Q

on the max 1st molar which root is the most likely to have a concavity?

A

the MB root (94%)

57
Q

the furcation entrance is smaller than the curette ________% of the time

A

58%

58
Q

what tooth is most common to have palatogingival groove?

A

max incisors
lateral most common (5%)

59
Q

what prosthetic and restorative factors will determine prog?

A

abutment selection
caries
non-vital teeth
root resorption

60
Q

what’s the key pt factor that affect prog.?

A

smoking
-has the most negative impact on tooth survival
-246% greater chance of tooth loss (compared to non-smoker)

61
Q

what are the key local factors that affect prog.?

A

probing depth
mobility
furcation involvement
% bone loss

62
Q

what’s the prog.?
-56 yr old female
-non-smoker
-hypothyroid well-controlled synthroid
-CL III mobility
-11 mm pd’s with suppuration
-#25: non-vital

A

hopeless

63
Q

what’s the prog.?
34 yr old female
non-smoker
healthy
-3 mm recession facial #25 with MGD
