Research on microbial contamination of individuals clothings has shown a variety of microorganisms. This contamination may cause infection and disease. The aim of this study was to determine the type and amount of aerobic bacterial contamination of dental student’s gown of Dental School of Shahid Beheshti University of Medical Sciences before and after treatment in 2013. During the study period 30 male dental students were selected by convenience sampling from restorative and periodontics departments. Sampling was performed from three part of gown before and after treatment using moistened sterile swab. The colony forming units were assessed and isolated bacteria were characterized by morphological and biochemical analyses. Statistical analaysis was performed using the Chi-square and Cochran Q test. P<0. 05 was considered as statistically significant. After finishing the treatment، in of 86. 7% of samples، the contamination was increased. The greatest contamination was related to Gram-positive bacteria. The Staphylococcus areus was the most common type of bacterium. Bacterial contamination of student’s gown is considerably increased after treatment of each patient. Therefore it is recommended that the surfaces near the patient are kept clean and sanitary measures are undertaken by the dental personnel during treatment in order to reduce microbial contamination.
