Background: Because of its role in the incidence of serious microbial infections, the contamination of dental unit water lines is concerned. The aim of this study was to evaluate the bacterial contamination of dental unit water lines to gram-positive cocci at Kerman.
Materials and Methods: This cross-sectional study was carried out in Environmental Health Engineering Research Center of Kerman University of Medical Sciences (KUMS) during 2015. Randomly 4 units among each of the departments of Dental School of KUMS (Pediatrics, Orthodontics, Oral surgery, Maxillofacial and Oral medicine) were selected. Samples were transported to the laboratory in sterile containers.  
Results: No contamination to gram-positive cocci in drinking water samples were reported. Among the water samples taken from Dental School the highest bacterial count was for the Oral medicine department (the cup filler unit 26/25 cfu/mL and 32/18 cfu/mL and the lowest bacterial count was for Oral surgery, Maxillofacial  departments [parts exposed to the weather unit  23/25 (cfu/mL) and  24/43 (cfu/mL)].
Conclusion: The prevalence of gram positive cocci in dental units of the departments was high. The dentists should care to the presence of microorganisms and take preventive measures to reduce the risk of infection among the department staff and patients.
