infection + inflammation of teeth + jaws Flashcards
what causes internal resorption
chronic pulpitis
what process can offer some natural protection to the pulp
odontoblats produce reactionary dentine
finding in teeth with open apex + caries
pulp polyp - granulation tissue
what is a periodical granuloma
chronic periodical periodontitis
radiographic sign of sclerosing/condensing osteitis
diffuse radio-opacity usually around periphery of widened periodontal ligament or periodical granuloma
associated with chronic AP
how to tell difference between acute and chronic PAP on radiograph
acute - not well defined
granuloma well defined
what treatment may you consider if end fails to resolve PAP
apicectomy
management of pericoronitis
irrigate with saline
+/-antibiotics
salt water + CHX rinse + OH
which muscle influences maxillary infections
buccinator - if spreads above it spreads into the superficial tissues of the cheek
cervofacial infection indistinguishable from acute dentoalveolar abcess
actinomycosis
symptoms of osteomyelitis
pain, tenderness, swelling
numbness at chin - IAN involvement
radiographic characteristic of osteomyelitis
moth eaten - may have radiopaque areas (sequestra)
predisposing factors to developing osteomyelitis
depressed immune or inflammatory response e.g. diabetes
bone abnormalities - pages disease or cement-osseoud dysplasia
management of osteomyelitis/osteoradionecrosis
antibiotics
removal of necrotic sequestra
why is the mandible more susceptible to osteoradionecrosis
less vascular
