Odontogenic Infections or Lessions are of bacterial or inflammatory origin penetrate primarily into the soft and bony oromaxillofacial tissues to produce submucosal infiltrates and abscesses. These infections are typically polymicrobial, and anaerobic bacteria are thought to play a central etiologic role. Antibiotics are an important component in the treatment of odontogenic infections. The drugs most frequently recommended are penicillin (PEN), amoxicillin-clavulanic acid (AMC), and clindamycin (CLI)—despite reports of substantial resistance to CLI among oral pathogens.The Incidence of Odontogenic Infections in Finland was increased from 5.3 to 7.2%. The Need for Intensive care increased from 15% to 32% in Finland.
Odontogenic infections are usually attributed to the endogenous flora of the mouth, and not to the introduction of non-resident bacteria. An important feature of suppurative odontogenic infections is that they are typically polymicrobial in nature, with mixed aerobic and anaerobic bacteria present.
