The mean score of knowledge about infection control during intraoral radiographs was more than 50% and it was evaluated as moderate. There was no statistically significant difference between the mean score of dentists' knowledge in terms of gender (P=0.623), age (P=0.849), work experience (P=0.824) and the year of their graduation (P=0.860), but there was a statistically significant difference between the mean score of dentists' knowledge according to their university of study (P=0.015), so that Yazd School of Dentistry graduates had significantly less knowledge than graduates of other faculties.
