endo-perio/bleaching Flashcards
three main avenues for communication between periodontium/pulp
dentin tubules
lateral and accessory canals
apical foramen
perio problems that become endo problems
pulp inflammation may occur from exposure of large lateral canals w/ bone loss
t/f: pulpal necrosis can ONLY occur when the main apical foramen is affected
TRUE
consider endo lesions that start as the result of lateral canals…wont be necrotic?
endo problems that become perio problems
inflammatory byproducts of pulpal origin (pulpal diagnosis = necrotic) connect to periodontist via apical foramen or lateral/accessory canals
t/f: a vital tooth can cause swelling or bone destruction
FAAAALse
endodontic pockets characteristics
narrow defects
isolated to involved tooth
may be associated with NECROTIC tooth or a fracture
periodontal pockets characteristics
wider defects
not isolated to one tooth
look around mouth for generalized condition
primary endo classification
source: tooth
dx: endo testing, any perio findings should be GENERALIZED
tx: RCT
primary perio classification
source: periodontist (NOT TOOTH)
dx: periodontal testing, endo testing should reveal VITAL pulp
tx: periodontal therapy
how do you differentiate endo problem from perio problem
pulp testing!!!!!! perio = vital
primary endo with secondary perio classification
source: tooth extending out into periodontium
dx: endo testing and perio probing
tx: RCT (perio should resolve after)
primary perio with secondary endo classificaiton
source: periodontium
dx: perio and endo testing
tx: RCT and periodontal therapy (usually by the time the pulp is involved the problem is too severe to save the tooth tho)
true combined classification
source: pulp and periodontium (endo lesion merges with perio pocket)
dx: perio and endo testing
tx: RCT, perio therapy, possible surgery, extraction?? depends
if a combination lesion exists, always treat ________ first
endo
can perio treatment resolve and endodontic condition?
NO
