Objective: The aim of the present study was to compare the self-reported oral health knowledge, habits and attitudes of adults in Portugal, Romania and Sweden, each benefitting from a different oral health system.
Methods: A cross-sectional study was conducted on 1081 adults in the three countries, using an adapted version of the WHO oral health questionnaire. This survey took place between November 2015 and June 2016.
Results: The mean age of the respondents was 46.85 with 95% CI (45.84, 47.86). Over 85% of the Portuguese and the Swedish, but only 55% of the Romanians, reported having 20 or more teeth left (P < 0.001). Most Swedes visit the dental office regularly, but only 50.5% of the Portuguese and 20.6% of the Romanians do so (P < 0.001). Interdental cleaning aids and fluoridated toothpaste were used the most in Sweden and the least in Romania. Daily consumption of sweets was lowest for Portugal and highest for Romania (P < 0.001), and daily intake of fresh fruits and vegetables was lowest for Sweden (P < 0.001).
Conclusions: There is a difference between the three countries regarding oral health, diet, dental attendance and oral health-related quality of life, with Romania being in most need of improvement in these areas. The differences could be explained by the distinct healthcare systems adopted by the countries.
