Alveolar Periostitis

• Infection and inflammatory mediators usually spreads from pulp to produce the periostitis.
• This may then affect the surrounding bone causing osteomyelitis.
  • Sometimes seen when infection of carnassial teeth in dogs results in a chronic sinus discharging below eye. So called 'malar' abscess.
• Only treated by removal of tooth.
• Hard to evaluate on mandible, may produce fistula that also needs tooth removal.
