Porphyromonas
Prevotella
Periapical abscesses and smell
Where do proteolytic bacteria grow best
apically where serum and cellular proteins are
During apical periodontitis, bacteria are most numberous in
Root canal
Most periapical lesions are
granulomas
What type of immune cells dominate in periapical granulomas
Macrophages
How to treat persistent apical lesions
Root may be irregular and you cant do conventional therapy. Must do Apicoectomy
Odontogenic infections location
Beyond tooth into dentoalveolar area
Odontogenic infection type of infection
Initial: cellulitis
Secondary: necrosis and abscess
Upper vs lower cellulitis
Upper is dental half the time
Lower is dental almost all the time
Cellulitis vs abcess organisms
Cellulitis: facultative
Abscess: anaerobe
Alveolar osteitis treatment
Debridement
Time
Antibiotics dont work but there is biofilm formation on bone
Osteomyelitis of jaw treatment
Debridement
Longterm antibiotics
MRONJ treatment
Debridement
Remove antiresorptive drugs
