Etiology of bacterial infections in the field of oral surgery was studied. A total of 270 samples collected from patients with encapsulated abscess in their oral cavities was examined and bacteria were isolated from the 244 samples (90.4%). The following results were found;<BR>1) Organisms more than one from one sample were frequently isolated from cases with parodontitis, pericoronitis and gnathitis. Isolation of anaerobic bacteria was common (54.2%).<BR>2)<I>Streptococcus milleri</I> and <I>Streptococcus sanguis</I> and <I>Capnocytophaga</I> species were the most common isolates among aerobic gram-positive and gram-negative bacteria, respectively.<BR>3) <I>Peptostreptococcus micros</I> and <I>Eubacterium lentum</I> were most frequent isolates among gramnegative anaerobic bacteria. Among gram-negative bacteria, Oral Group <I>Bacteroides</I>, especially <I>Bacteroides gingivalis, Bacteroides intermedius, Bacteroides buccae</I> and <I>Bacteroides oralis</I> were most prominent.<BR>4) Isolation frequency of bacteria (both species and strains) was high from samples obtained from patients before antibiotic chemotherapy.<BR>5) Most strains were sensitive to Midecamycin acetate and Josamycin. Minimum inhibitory concentration of 80% isolates (MIC<SUB>80</SUB>) against these antibiotics was 0.39μg/ml.
