Study Notes
Etiology of Osteomyelitis
- Osteomyelitis is typically caused by bacterial infection, often due to hematogenous spread from bacteremia or direct inoculation from a contiguous source of infection.
Microorganisms Associated with Odontogenic Infection
- Microorganisms associated with odontogenic infection in osteomyelitis include Streptococcus spp., Staphylococcus spp., and anaerobic bacteria.
Predisposing Local Factors for Osteomyelitis
- Predisposing local factors for osteomyelitis include trauma, surgical procedures, fractures, and infected soft tissue.
Types of Chronic Osteomyelitis
- There are two main types of chronic osteomyelitis: chronic diffuse sclerosing osteomyelitis and chronic focal sclerosing osteomyelitis.
Chronic Diffuse Sclerosing Osteomyelitis
- Chronic diffuse sclerosing osteomyelitis is characterized by diffuse bone sclerosis and is often associated with mandibular infections.
Chronic Focal Sclerosing Osteomyelitis
- Chronic focal sclerosing osteomyelitis is characterized by focal bone sclerosis and is often associated with periapical infections.
Non-Predisposing Factor
- Good oral hygiene is not a predisposing factor to osteomyelitis.
Etiology of Specific Osteomyelitis
- Specific osteomyelitis caused by hematogenous spread from bacteremia is often caused by Staphylococcus aureus and β-hemolytic streptococci.
Definition of Osteomyelitis
- Osteomyelitis is a term that describes the inflammation of bone and its marrow contents.
