perio-endo relationships Flashcards
Deep Caries, Trauma (accident), and Restorative procedures can all create a risk of injury to what?
the pulp vitality
the frequency of accessory pulp canals increases towards the _______
apex
__________ are often found near furcations
accessory canals
what is a Primary perio-endo lesion?
an infection of the pulp (direct infection of the pulp, not due to any perio involvement)
causes inflammation (periodontitis) of the surrounding perio tissues
what is a secondary perio-endo lesion?
inflammation of pulp tissue due to accumulation of plaque on root surface
periodontal problems inducing changes in pulp
what is the 3rd class of perio-endo lesions?
a “true” combined perio-endo lesion- Pulpal and periodontal pathologies initiate independently and coalesce
patient has BOTH periodontal problems, and direct endodontic inflammation
T/F: in a “true” combined perio-endo lesion, the periodontal infection causes inflammation in the pulp
FALSE
in the combined lesion (3rd class of perio-endo lesions) the periodontal and pulpal infections are independent of one another, but occur at the same time
T/F: Studies have failed to confirm direct relationship between progression of periodontitis and pulp changes
true
how can periodontal bacteria access the pulp?
Accessory canals
Apical foramen
Dentinal tubules
what are the endodontic therapy complications that can lead to periodontal infections?
Perforations, vertical fractures
how does periodontitis lead to sensitivity of the pulp?
Root exposure (recession)
Cementum (and dentin) removal
Dentinal tubule exposure
what condition has the following characteristics:
- Sharp pain, rapid onset
- Peak at 1st week, then subside
- Various stimuli elicit response
dentin hypersensitivity
