Q

what does grade 1, 2, 3 mean?

A

1 - horizontal loss less than one third
2 - horozontal loss over one third
3 - through and through furcation

17
Q

why do furcations reduce the prognosis of a tooth?

A

harder to clean = hard to control disease in the area

poss loss of vitality b/c accessory canals - bacteria get to pulp

18
Q

what is used to vitality test a tooth?

A

ethyl chloride

electric pulptester

19
Q

how often to regrade a furcation?

how often to vitality test?

A

regrade 6 monthly or yearly

vitality test yearly

20
Q

how to treat furcations?

A

expose furcation for easy cleaning access

induce regeneration of new bone

21
Q

tx for degree 1?

A

s/p
RSD
furcationoplasty

22
Q

tx for degree 2?

A 
furcationoplasty
tunnel prep
make it through and through
GTR
root resection
tooth extraction
23
Q

tx for degree 3?
