1/15 endo- perio Flashcards
pathways to endo perio lesions -anatomical factors
anatomical factors
- apices
- lateral accessory canals
- dentinal tubules
lateral vs accessory canals
accessory – extend from pulp / endodontium to perforate through perdontium
lateral canals - more for coronal or middle 1/3
more apical – more accessory canals
% of teeth with lateral canals
44%
most in the apical thirds
furcational canals
may / may not communicate with the pulpal floor
90 % of accessory canals
located in the apical 1/3 of the root
anatomical vulnerability in dental tubule exposure
nature of the pentrating agent
nature of exposed
this is not done card
main pathway for endo perio lesion
apex
etiologic factors in endo - perio
primarly gram negative pathogens
most prevelant
- poryphomonas, prevotella, adn fusobacerium species
contributing factors to endo perio
poor endo tx
poor restoratinos
trauma
perforations - iatrogenic
resorption
example -external resorption
developmental malformations
deep probings can indicate ___ in terms of diagnosing
periodontal involvment
when does percusssion get involved
PDL involvment - like inflammation in the PDL
mobility as a diagnostic tool
when tooth has over physiologic mobility
means the PDL s widened - the ligament is widened
pulp testing will show us
inclusion or exclusion of endodontic involvment
deep probing automatically means
periodontal involvment
fistula tracking
tend to see this clinically
