review of endo principles Flashcards
what is endodontology
it is concerned with the study form function and the health of injuries/diseases of the pulp and peri radicular region and their prevention and treatment
what is the principle disease of endodontology
apical periodontitis caused by infection
what causes endodontic diseases
microorganisms
host response
time
what type of endodontic microbiology do we see in the apical region of a tooth
lower oxygen tension
nutrients from peri radicular tissues
lower bacterial counts
bacteria less accessible to treatment
what type of endodontic microbiology do we see in the coronal region of a tooth
high oxygen tension
nutrients from the oral cavity
high bacteria count
microorganisms are more accessible to treatment
what is the nature of the root canal microflora
can be planktonic or bacterial biofilm
how does bacteria biofilm root canal bacteria act
it aggregates in a sold structure
difficult to remove as it gets stuck to the wall
how do we diagnose endodontic disease
reliant on pt pain description
what else can we use to help diagnose endodontic diseases
special tests
radiographs
TTP
CBCT
what are the steps for RCT
isolate access chemo mechanical prep irrigation temporisation obturation
how do we isolate for RCT
rubber dam!
medico legal requirements
how do we carry out chemo mechanical prep
double flare technique
flare the coronal third
flare the apical third
and blend together to connect
what is patency filing
-using usually a size 10 file to clear the apex of any debris and aid irrigant flow: we will be doing this more commonly
what is recapitulation
checking that the master apical file still passes to working length
how do we manipulate files
stem winding
