    Abstract:
    UNLABELLED: The main aim of this thesis was to study the oral health and the self-perceived oral treatment need of adults in Sweden. The first step was to analyse the self-perceived oral treatment need in a random national sample of young adults (20 to 25-year-olds). This study used one patient and one dentist questionnaire. The patient questionnaire was sent to 611 young adults and the response rate was 78%. After permission from 377 of these individuals, a questionnaire was sent to their dentists and answers were received from 85% (321 dentists). How the individuals perceived their oral treatment need was used as a dependent variable in a multivariate logistic regression model. Independent variables were self-assessed socio-economic situation, general health and dental attitudes together with information from the dentists on their patient's dental status. The results showed that having a high educational level, poorer oral health compared to one's peers, and being concerned about one's oral health significantly increased the odds for a high perceived oral treatment need. In this group of young adults, 33% perceived a high oral treatment need. In order to study if the oral treatment need was the same in all adult age groups and how the perceived oral health was in an adult Swedish population, a new questionnaire was sent to a random sample of 9 690 individuals, 20 to 89-year-olds, living in Skåne, Sweden. The response rate was 63%. The results showed that a majority of the adult population in Skåne had a positive perception of their oral health, in particular the individuals in the youngest age group. Most individuals had lost few teeth and removable dentures were uncommon. One third rated their dental treatment need as high. The highest proportion of individuals with a perceived high oral treatment need was found in the age group 70-79. In order to study the perceived oral treatment need in all adult age groups, the questionnaire was further analysed. The Andersen behavioural model was used as a theoretical framework for a multivariate logistic regression model. Questions that fit the components of individual characteristics, health behaviour and outcomes in the model were used as independent variables. The self-perceived oral treatment need was used as a dependent variable. The results showed that the Andersen behavioural model was found to be a useful tool when studying the perceived oral treatment need, and variables from all of the components in the model were significant. Important factors for the prediction of a high oral treatment need were a low educational level, previous unmet perceived oral treatment need, frequent visiting pattern, perception of worse oral health, external locus of control, and to have received information from one's dental caregiver about a need for oral treatment. The evaluated oral health was also studied using another sample of adults from the same region and of the same age. 966 individuals were invited to participate in a clinical study and 47% of the final sample was examined. Since socio-economic factors have been shown to be related to oral health, the clinical findings were studied in cross tabulations and chi-2 tests together with age, gender, ethnicity and educational level. The results showed that older age was related to a higher prevalence and an increased severity of oral diseases (except for caries) and a higher number of dental restorations. There were no significant differences between the genders. Individuals with a lower educational level had fewer teeth remaining, had more caries lesions, and had worse periodontal conditions and a higher DMFT. Individuals not born in Sweden had fewer teeth remaining, had worse periodontal conditions, more apical destructions and had received less dental fillings than those born in Sweden. CONCLUSIONS: The self-assessed and the professionally evaluated oral health of the adult population in Skåne is good both in a historical and international perspective. The evaluated oral health is comparable to other Swedish studies. There is, however, a group of individuals that has an increased risk for oral diseases. The self-perceived oral treatment need is largely affected by the patient's socio-economic background and perceptions of oral health.
