Iranians' attitudes about possible human immunodeficiency virus transmission in dental settings.

We conducted a cross-sectional survey from October through December 2004 of 8,312 residents of Shiraz, Iran, to investigate Iranians' perceptions about undergoing dental treatment in dental offices where other patients or the dentist and/or dental assistants are infected with human immunodeficiency virus (HIV). Most survey respondents (83%) had acceptable general knowledge about the mode of transmission of HIV and about acquired immunodeficiency syndrome (AIDS); however, many misconceptions were observed. A negative association was detected between the level of concern about contracting HIV/AIDS and the intention to continue treatment in services where patients with HIV/AIDS were also treated or where the dentist and/or dental assistants had HIV/AIDS.
