Microflora in odontogenic infections

Abstract

Purpose: This study was intended to evaluate the various causative microorganisms responsible for fascial space infections. Materials and Methods: A total of 88 patients who reported with an orofacial space infection of odontogenic origin were included in the study. Following a thorough evaluation, using a disposable syringe, pus sample was obtained and sent for culture and sensitivity test. Offending teeth were extracted under antibiotic coverage, and incision and drainage was done as and when indicated. The results of the culture and sensitivity along with the effective antibiotic were tabulated. Results: The results of this study show that submandibular space (38.8%) is the frequently involved fascial space. Majority of the patients are in the second and third decades of life (53.9%). Staphylococcus species (41.1%) is the most commonly isolated microorganism. Penicillin remains to be the drug of choice. Extraction of the offending tooth under antibiotic coverage and incision and drainage remains to be a treatment option. Conclusion: Based on the results of this study, it can be concluded that the causative microorganisms for odontogenic infections involved mixed aerobic–anaerobic bacteria. Anaerobic as well as aerobic cultures were necessary to isolate all pathogens.
