Odontogenic infections: Microbiology and management

Abstract

Objective:The aim of this retrospective study was to evaluate the involvement of fascial spaces, their bacteriology, sensitivity to antibiotics and management of odontogenic infection in 100 patients of age less than 60 years.Resuls:The mandibular 3rd molar was found to be the most commonly offending tooth, followed by the mandibular 2nd molar. The submandibular space was the most frequently involved fascial space both in single fascial space infections and multiple fascial space infections. Mixed growth (aerobic and anaerobic) was seen in culture smears of 60 patients, only aerobic bacterial growth was seen in 25 patients and anaerobic bacterial growth was seen in culture smears of 15 patients. Streptococcus viridans was the most frequently isolated bacteria among the aerobes, whereas Bacteroides and Prevotella were the most common bacterial species among anaerobes. Empirical antibiotic therapy in the form of Co amoxiclav and Metronidazole was given. Incision and drainage followed by extraction of the offending tooth/teeth was carried out.Conclusion:It was concluded that odontogenic infections were mixed aerobic–anaerobic infections. Anaerobic as well as aerobic cultures were necessary to isolate all pathogens. Successful management of these infections depends on changing the environment through decompression, removal of the etiologic factor and by choosing the proper antibiotic.

Odontogenic infections in a dental emergency care unit: Eleven-year epidemiological analysis

“…Clinical data, images, and laboratory tests can determine if there is a localized infection or suggest the propagation of infection 1 , and, based on these findings, therapeutic modalities are chosen. However, the most important procedures for orofacial suppurative infections are surgical drainage and removal of the primary source of infection 5 . In this study, treatment procedures were divided as follows: extraoral drainage, intraoral mucosal drainage, periodontal drainage, and endodontic drainage.…”

Therapeutic Strategies in Dental Origin Mediastinitis: Cases Report

“…In 58% of DNM cases (30% to 75%), is a polymicrobial infection, mainly by gram-positive, such as streptococcus (43% to 62%) and anaerobic (46% to 78%) bacteria, and less frequently (except in patients with diabetes) by gram-negative enterobacterias, such as Klebsiella (4% to 8%) [5], Prevotella buccae [9]. In all cases we reported the gram-positive streptococcus which comes originate from the oral cavity [10] and the skin. Enterobacteriaceae were also an etiologic factor for mediastinitis after cardiac surgery [11], where there is no direct contact with the oral cavity.…”

“…Infekcijų vystymuisi sudaromos tinkamos sąlygos esant užleistoms ar netinkamai gydomoms burnos ligoms. Tyrimų duomenimis, pirminiai infekcijos "vartai" dažniausiai aptinkami 2 -3 -jame krūminiuose dantyse [5,11,12].…”

“…Infekcijų vystymuisi sudaromos tinkamos sąlygos esant užleistoms ar netinkamai gydomoms burnos ligoms. Tyrimų duomenimis, pirminiai infekcijos "vartai" dažniausiai aptinkami 2 -3 -jame krūminiuose dantyse [5,11,12].Neretai ši patologija tampa iššūkiu siekiant gerų diagnostikos ir gydymo rezultatų. Ankstyvoje infekcijos stadijoje atsiradę simptomai -skausmas, patinimas ar sutrikęs prasižiojimas -būna mažai išryškėję, todėl dažnai tinkamo gydymo paskyrimas būna pavėluotas.…”
