Spread Of Infection Flashcards
The inflammation of pulp tissue which can be reversible or irreversible
Pulpitis
Infection spread into periapical tissue causes…
Periapical periodontitis
Accumulation of pus within the PDL
Periodontal abscess
Inflammation of the surrounding tissue around a partially erupted wisdom tooth
Pericoronitis
Odontogenic infection within the confines of the jaw
Osteomyelitis
What would you diagnose if:
Toxins from carious bacteria stimulate an acute inflammatory reaction within pulp tissue
Reversible pulpitis
What would you diagnose if:
Bacterial colonisation of the pulp occurred which could lead to pulp necrosis if untreated
Irreversible pulpitis
How would you treat irreversible pulpitis?
Root canal treatment
What would you diagnose if:
Toxins from carious bacteria move into PDL space, triggering acute inflammation.
Periapical periodontitis
How can toxins from bacteria move from the pulp into PDL space to cause periapical periodontitis?
Through lateral canals off pulp chamber
What does acute inflammatory reaction of the PDL stimulate?
A build up of hydrostatic pressure and subsequent build up of fluid
What triggers osteoclastic bone resorption?
Hydrostatic pressure and fluid pressure on the adjacent bone
What leads to bone loss around the apex of a tooth?
Osteoclastic bone resorption
how would periapical periodontitis appear on a radiograph?
As a periapical radiolucency and loss of lamina dura
What would be the next step in treatment of periapical periodontitis id endodontic treatment fails?
Extraction of the tooth
The final stage of periodontitis, generally non-painful condition that presents in the apical portion of the apical canal around the apex of a tooth, causing long-lasting inflammation.
Chronic periapical periodontitis
What Odontogenic infection is associated with periapical cyst formation?
Chronic periapical periodontitis
What is a very rare, but possible extra oral swelling as a result of chronic periapical periodontitis?
Oral cutaneous fistula
How does swelling relating to periapical periodontitis usually initially present?
Intra-orally
