Tooth loss among Saudi adolescents: Social and behavioural risk factors

Abstract

Objectives: To examine the prevalence of tooth loss in Saudi adolescents, to investigate the reasons behind such loss and to identify any associated social and behavioural factors. Methods: A cross-sectional study was carried out in the Eastern Province of Saudi Arabia, from March 2006 through January 2007. A total of 484 subjects, aged 14-19-years of age, were included in the study. The subjects had a clinical examination and completed a self-administered questionnaire regarding their demographic, social, oral and general health attitudes. The prevalence and mean tooth loss were calculated, and a binary regression model was used to construct a risk prediction model. Results: A 90% response rate was achieved. The prevalence of tooth loss was 40.9% (n = 198). Permanent first molars were the most frequently missing teeth (57.1 %). The overall mean tooth loss was 0.83±1.18. Both the proportion and mean tooth loss were significantly associated with sweet consumption, smoking, tooth brushing, dental flossing, dental visiting pattern and self-rated oral health. In logistic regression analysis, five social and behavioural factors had significant independent effects. Conclusions: Several socio-behavioural characteristics have been related to the high prevalence of tooth loss among Saudi adolescents. Tooth loss should be urgently addressed through implementation of community preventive programmes in Saudi Arabia. © 2008 FDI/World Dental Press.
