6-Bone Inflammation Flashcards
What is osteolyelitis?
bone marrow inflammation with possible suppuration (pus formation)
Acute Osteomyelitis clinical presentation?
Significant pain Fever WBC rise Swelling of overlying tissues/lymph nodes Pus Necrotis bone sequestra Parasthesia
Radiographic appearance of Acute Osteomyelitis?
ill-defined, asymmetric radiolucency
Treatment for Acute Osteomyelitis?
antibiotics!!
surgical drainage if not spontaneous
Chronic Osteomyelitis clinical presentation?
Variable pain
Swelling
Tooth loss
Radiographic appearance of Chronic Osteomyelitis?
ill-defined, asymmetric radiolucency
increased density
Treatment for Chronic Osteomyelitis?
IV antibiotics
long duration
What is Chronic Focal Sclerosing Osteomyelitis?
Condensing Osteitis, a reaction to low grade odontogenic infection where the tooth is NON-VITAL
Radiographic appearance of Chronic Focal Sclerosing Osteomyelitis?
irregular opacity, asymmetric and blends
What is Chronic Diffuse Sclerosing Osteomyelitis?
reaction to low grade odontogenic infection following trauma or surgery, but affects large area of bone in 1 quandrant
Radiographic appearance of Chronic Diffuse Sclerosing Osteomyelitis?
diffuse radiopacity of varying density in Posterior Md
What is Chronic Osteomyelitis with Proliferative Periostitis?
low grade osteomyelitis in younger patients, inflammation involves periosteum on or near cortical surface, draining sinus tract from an infected tooth most often
Radiographic appearance of Chronic Osteomyelitis with Proliferative Periostitis?
thin layering of cortical bone
Onion skin pattern
lucency under cortex
What is Alveolar Osteitis?
dry socket post extraction from loss/breakdown of blood clot
Treatment for Alveolar Osteitis?
packing of socket with protective dressing
Who does Alveolar Osteitis affect and why?
women because of birth control pills
What is Bisphosphonate-induced osteonecrosis (BRONJ)?
drug that inhibits action of osteoclasts also can affect angiogenesis (bone healing) and osteoblasts to increase bone density
What type of Bisphosphonate-induced osteonecrosis drug produces greater risk?
IV administration
Bisphosphonate-induced osteonecrosis clinical presentation?
bone necrosis
follows surgical procedures
Bisphosphonate-induced osteonecrosis best treatment?
prevention
What is Cemento-Osseous Dysplasia?
Non inflammation, non neoplastic, no genetic pattern defect in progenitor cells in the PDL which affects ability to remodel bone and cementum
What is Periapical Cemento-Osseous Dysplasia?
middle age remodeling bone/cementum defect affecting Blacks 70% and Females 90%
Periapical Cemento-Osseous Dysplasia clinical presentation?
anterior Md
Painless
TOOTH VITAL
Periapical Cemento-Osseous Dysplasia radiographic appearance?
anterior Md
apex
Progressive lucent to sclerosis fused to tooth root
Periapical Cemento-Osseous Dysplasia Tx?
None
DO NOT DO RCT
What is Florid Cemento-Osseous Dysplasia?
Middle age remodeling bone/cementum defect affecting Blacks and Females
Florid Cemento-Osseous Dysplasia clincal presentation?
multiple posterior quandrants in Md
painless
possible expansion
Florid Cemento-Osseous Dysplasia Tx?
Prevention
try to not take out teeth and keep gums healthy
What happens if Florid Cemento-Osseous Dysplasia lesions become infected?
large portions of bone may sequestrate
What is Focal Cemento-Osseous Dysplasia?
remodeling bone/cementum defect in Md, doesn’t follow normal classic population and common in EDENTULOUS areas
Focal Cemento-Osseous Dysplasia radiographic appearance?
opaque with lucent halo
