The aim of this study was to investigate self-perceived oral health in two elderly populations, age's 65 and 75 years, and its relation to background factors, socioeconomic, individual, and dental health service system factors. Another purpose was to investigate if there were any differences in these respects, between the two age groups, born in 1932 or 1942. In two counties in Sweden, Orebro and Ostergötland, all persons born in 1942 have been surveyed by mail every fifth year since 1992. In the year 2007 all persons born in 1932 were also surveyed using the same questionnaire. Those born in 1932 consisted of 3735 persons and those born in 1942 6078 persons. From an outline of a general model of inequalities in oral health data were analyzed with descriptive statistics and contingency tables with chi2 analysis. Multivariable analysis was performed by using multiple regression analysis. Factors related to self-perceived oral health were age group, social network, ethnicity, education, general health,tobacco habits, oral hygiene routines, dental visit habits and cost for care. The self-perceived oral health was overall rather high, especially in view of the studied ages, although it was worse for those of age 75. Socio-economic factors, dental health service system as well as individual lifestyle factors affected self-perceived oral health. To have a satisfying dental appearance, in the aspect of howyou are judged by other people, was important for these age groups. This presents a challenge for dental health planners especially since the proportion of older age groups are growing.
