title: Occurrence of odontogenic infections in patients treated in a postgraduation program on maxillofacial surgery and traumatology.
abstract: This study assessed the occurrence and characteristics of oral and maxillofacial infections in patients treated at a Brazilian oral and maxillofacial emergency service during a 7-year period. The clinical files of all patients treated at the Oral and Maxillofacial Surgery and Traumatology Service of the Araçatuba Dental School, São Paulo State University, Brazil, between 2002 and 2008 were reviewed. From a population of 3645 patients treated in this period, the study sample consisted of 93 subjects who presented odontogenic infections. Data referring to the patients' sex, age, medical history, and the etiology, diagnosis, complications, drug therapy/treatment, and evolution of the pathologic diseases were collected and analyzed using the Epi Info 2000 software. Of these patients, 54 were men (58.1%) and 39 were women (41.9%). Most patients were in the 31- to 40-year-old (20.7%) and 21- to 30-year-old (19.6%) age groups. The most frequent etiology was pulp necrosis due to caries (80.6%). Regarding the treatment, antibiotics were administered to all patients, surgical drainage was done in 75 patients (82.4%), and 44 patients (47.3%) needed hospital admission. First-generation cephalosporin alone or combined with other drugs was the most prescribed antibiotic (n = 26) followed by penicillin G (n = 25). Most patients (n = 85, 91.4%) responded well to the treatment. Five cases had complications: 3 patients needed hospital readmission, 1 case progressed to descending mediastinitis, and 1 patient died. Odontogenic infections can be life-threatening and require hospital admission for adequate patient care. Complications from odontogenic infections, although rare, may be fatal if not properly managed.
