On self-perceived oral health in Swedish adolescents.

Aiming to investigate adolescents' perceptions of oral health, with a focus on gender differences, quantitative and qualitative studies were conducted in Skaraborg County, Sweden. Adolescents (13-18 years; n = 17,280) answered a school questionnaire, epidemiological indices on oral health were collected, and 17 semi-structured interviews were conducted. Most adolescents perceived their oral health as good, girls more often than boys. The oral behavior of girls was also more often healthy (floss usage: girls 31%, boys 21%), and they were consistently less satisfied with the appearance of their teeth than boys. Girls considered their own consumption of candy to be too high more often than boys. Acknowledging the importance of sound teeth was strongly associated with self-perceived oral health: boys, odds ratio (OR) 8.58 [confidence interval (CI) 7.12-10.34]; girls, OR 5.56 [CI 4.23-7.30]. Adolescents living with a single mother (13-15-yr-olds OR 1.37 [CI 1.20-1.57], 16-18-yr-olds OR 1.51 [CI 1.28-1.77]), or with neither parent, more often reported bleeding gums than those who lived with both parents, while adolescents who lived with a single father did not. Weak correlations between epidemiological indices and self-perceived oral health were found at the school level. In the interviews, adolescents perceived the possibilities to influence their own oral health as limited. Perceptions of influences on oral health were related to personal and professional care, social support, social impact, and external factors such as time and economy. Support from the mother--more than from the father--was emphasized. This thesis showed that positive oral health attitudes and parental support are of great importance if oral health is to be perceived as good. There were gender differences in all issues related to self-perceived oral health.
