Tooth loss among Saudi adolescents: social and behavioural risk factors

Abstract

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. 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. 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. 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.
