The aim of this study was to investigate the situation of infection control among dental laboratories in Methods and Materials: The present research was a cross sectional and descriptive-analytical investigation. Data were collected from 38 dental laboratories by an author developed questionnaire. The questionnaire asked respondents for demographic data (age, gender and education) and to answer some questions about their knowledge and practice of infection control and measures including use of gloves, protective eyeglasses, mask and hepatitis B virus vaccination. The gathered data analyzed with fisher, and t-test using SPSS 13.5 statistical software (0= 0.05).Results: Among all of 103 respondents, 85 were male (82.5 percent) and 18 were female (17.5 percent). The most popular chemical materials used for disinfection were household bleach, glutaraldehyde, and alcohol. The results showed that 14 percent of technicians in laboratories wore gloves, and 7.7 percent regularly wore eyeglasses. Besides, 54 technicians (52.4 percent) had received HB V vaccination.Conclusion: The results of this study showed a lack of appropriate communication between dentists, and dental laboratory personnel in regards to disinfection of impressions and prostheses.
