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.

OBJECTIVES : To study the microbiology of sinusitis associated with odontogenic origin. METHODS : Aspirates of 20 acutely and 28 chronically infected maxillary sinuses that were associated with odontogenic infection were processed for aerobic and anaerobic bacteria. RESULTS : A total of 66 isolates were recovered from the 20 cases of acute sinusitis (3.3/specimen), 16 aerobic and facultativ...

BACKGROUND The aim of the study was to assess the value of pretreatment neutrophil/lymphocyte (N/L) ratio and mean platelet volume (MPV) and the correlation between these markers with progression in patients with severe odontogenic infection. MATERIAL AND METHODS A cohort of 100 patients with severe odontogenic infection were divided into 2 groups according to their length of hospital stay. T...

the term calcifying odontogenic cyst (coc) was first introduced by gorlin in 1962. coc occurs mainly as an intra-osseous lesion in mandible or maxilla but the peripheral variation of coc has also been reported. the confusion about coc nature as cyst or tumor has not been resolved and a vast diversity has been shown in clinicopathologic aspects of coc. the purpose of this study was the review an...

Antibiotics are commonly used in dental practice. It has been estimated that 10% of all antibiotic prescriptions are related with dental infections. The association amoxicillin-clavulanate was the drug most frequently prescribed by dentists during 2005, at least in the Valencian Community (Spain). The use of antibiotics in dental practice is characterized by empirical prescription based on clin...

Introduction Raoultella is a genus of aerobic Gram-negative bacilli belonging to the family Enterobacteriaceae that are commonly found in water, soil and aquatic environments. With improved bacterial identification techniques, Raoultella species (namely R. planticola and R. ornithinolytica) have been an increasingly reported cause of infections in humans. Case presentation An 85-year-old man ...

Most orofacial infections are of odontogenic origin, and are of a self-limiting nature, characterized by spontaneous drainage. The causal bacteria are generally saprophytes. On the other hand, invasive dental interventions give rise to transient bacteremia. When an oral lesion is contaminated by extrinsic bacteria, the required antibiotic treatment should be provided as soon as possible. In the...
