OBJECTIVES The increased prevalence of antibiotic resistance is an outcome of evolution. Most patients presenting with odontogenic space infections also have associated systemic co-morbidities such as diabetes mellitus resulting in impaired host defense. The present study aims to compare the odontogenic spaces involved, antibiotic susceptibility of microorganisms, length of hospital stay, and t...

Descending necrotizing mediastinitis a clinical entity formed by the spreading of cervical infection from dental and oropharyngeal structures through deep cavities between fascia on neck to mediastinum, pleural pericardial spaces with necrosis soft tissue has high mortality. Herein we present case 73-year-old admitted emergency department septic clinic. The patient was diagnosed descending due ...

D eep neck space infections are a potential complication of odontogenic infection, but rarely have been reported in children. In a recent study, 113 pediatric patients were hospitalized with maxillofacial infections with 32 from dental sources; however, the extension of these infections into deep neck spaces was not documented. 1 In a similar study of 67 children with abscess of the head and ne...

Ludwig's angina is a potentially life threatening diffuse cellulitis usually resulting from odontogenic infection. We report a case of Ludwig's angina resulting from self administration of an acidic chemical to treat toothache.

Intracranial abscess is one of the most serious complications of frontal sinusitis, particularly among adolescents, even in the absence of odontogenic infection. Polymicrobial infections due to anaerobes are common. Because antibiotic therapy alone is usually ineffective, early endoscopic sinus surgery is the key for infection control and good clinical outcomes.

Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagno...

Squamous cell carcinoma (SCC) arising within the lining of an odontogenic keratocyst (OKC) is a rare occurrence. Although potentially locally destructive, OKC is a benign odontogenic process that typically presents with clinical and radiographic features characteristic of a benign intraosseous neoplasm. We present the clinical and radiographic features of a maxillary mass that demonstrated SCC ...

The dental biofilm is a complex bacterial ecosystem that undergoes evolution, maturing and development, and thus leads to odontogenic infection. The infection is normally located in the tissues of the dental organ itself, and follows a chronic course of evolution. However, bacterial pathogens express virulence factors in the biofilm, and this together with changes in host immunity, may cause cl...
