Bacterial Microbiology and Antibiotic Sensitivity in Maxillo-mandibular Infections

Abstract

Oral cavity is important functional structure of the body, like other parts of the body it contains micro bacteria as a commensally structures. Several species of bacteria present in the mouth that exploit the circumstances of human immunity and oral hygiene to cause infections which can spread to the facial region and neck to the rest of the body and lead to serious outcome. Background: Determine most common bacterial microorganisms and antibiotic sensitivity of maxillomandibular infections. Materials and Methods: A descriptive study was carried out on 45 patients with different forms of maxillomandibular infections, data regarding age, gender, presenting signs were collected through history, clinical examination and radiographs, incision and drainage with swab sample for culture and sensitivity test was done. Results: Patients with maxillomandibular infections showed a male to female ratio of 1:1.25 The mean age was 33 years. Most of the patients were in the 4th decade 27% of life, most common isolated microorganism was Streptococcus pyogene 59%, antibiotics with greatest sensitivity were Netilmicin, Cefoperazone and Rifampicin 91%.
