1. Infection in the oral and maxillofacial region can arise from bacteria that exist in the oral and nasal cavities. Factors like temperature and moisture allow bacteria to reproduce and develop. 2. Common sites of odontogenic infection include the tooth, alveolar bone, and soft tissues which can lead to conditions like caries, pulpitis, apical infection, or facial space infections. 3. Diagnosis involves identifying local signs and symptoms like pain, swelling, and pus formation as well as systemic signs like fever. Treatment involves use of antibiotics, surgical drainage and incision to rid the body of toxic materials and allow tissues to heal.
