title: Odontogenic Infections: A 1-year Retrospective Study.
abstract: The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital.
  
  
  
  In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis.
  
  
  
  A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%).
  
  
  
  Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics.
  
  
  
  Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.
