Dentoalveolar infections include a wide range of conditions from localized abscesses to deep-neck space infections or more severe cases of necrotizing fasciitis. Odontogenic infections and emergencies are a significant part of an oral and maxillofacial surgeon's daily practice. On a daily basis, an oral surgeon needs to be prepared to deal with any infection-related emergencies ranging from a toothache, localized vestibular abscess to deep head and neck abscesses. Management of these odontogenic infections could propose a challenge due to complex microbiology of the odontogenic infection and the potential for advancement to a life-threatening emergency. It is crucial that the oral and maxillofacial surgeon has knowledge of anatomic boundaries and fascial spaces to be able to make an accurate diagnosis and perform prompt surgical management. For the patient, odontogenic infections may carry high incidence of morbidity and mortality if not treated promptly. Management of patient with an odontogenic infection is a multifaceted approach involving (1) an examination and assessment of the patient, (2) identifying the source of the infection, (3) anatomic considerations, (4) surgical intervention, (5) administration of the appropriate antimicrobial therapy, and (6) referral to an appropriate provider if indicated. This chapter provides the clinician with a better understanding of diagnosis and pharmacological management as well as surgical treatment of patients with odontogenic infections.

This clinical report focuses on the challenges and solutions for a child subjected to craniofacial trauma from a wild hyena biting off his nose and anterior maxilla. Unique considerations in prosthodontics and biomedical engineering were required based on future craniofacial growth and development of the child. The physical requirement of a maximum retentive prosthesis for an active, athletic child required unique engineering designs and executions. The sequence of treatment and prosthesis fabrication are detailed. The patient has been followed for 9 years without physiologic complications and only minor prosthodontic complications.
