Determining what people know and believe about periodontal health and disease is important in order to establish prevention practices. This study aimed to assess knowledge of and attitudes towards periodontal health among adults in Tehran, Islamic Republic of Iran. We conducted a cross-sectional face-to-face interview survey in 2011 of 791 adults aged 18-50 years using a stratified, multistage sampling method. We recorded demographic characteristics including age, sex, education, marital status, employment and economic status (housing density). The lowest percentage of correct answers was related to the definition of dental plaque (11.6%) and the highest was for the role of the dental visit in prevention (92.8%). Female sex, university education and higher economic status were significantly associated with a higher mean score on periodontal health knowledge. The regression analysis showed that positive attitudes were associated with higher periodontal health knowledge and having university education. In this study positive attitudes towards prevention were related to better knowledge.
