Oral health and quality of life in New Zealand: A social perspective

This study addresses the social dimensions of oral health by relating oral quality of life (i.e. dental symptoms, perceived oral well-bring and oral Functioning) to oral health status. We propose a conceptual model which postulates that socioeconomic status, oral health behavior and oral health status each influence oral quality of life. Using data from the New Zealand National Oral Health Survey, we describe and analyze oral health status and oral quality of life among children aged 12-13 and adults aged 35-44 and 65-74. The study demonstrates the impact of oral health problems on the oral quality of life of children, middle-aged adults and older adults in New Zealand. The majority have experienced at least one dental symptom in the past year. Some of them perceive poor oral health and also dislike the way their teeth/dentures look. Various aspects of their social and physical functioning are adversely affected by oral health problems. The results of multiple regression analyses of oral quality of life demonstrate that perceived general health is a consistent predictor of quality of life. Furthermore, the adults' oral quality of life is positively related to asymptomatic dental visits and negatively related to symptomatic dental visits. Children's oral quality of life is positively related to more frequent brushing and Bossing. Oral health status is closely associated with oral quality of life for both adults and children. Analyzing the New Zealand oral quality of life data and reviewing previous research findings using a conceptual model provide the possibility for a more comprehensive and integrated understanding of oral quality of life issues.
