A global increase in the prevalence of dental caries is a pending public health crisis. Gingival bleeding and dental plaque are common in children worldwide. Reducing the burden of oral diseases in children is a global goal of the WHO. Oral health promotion programs should consider determinants of oral health. This book covers the main areas of oral public health, i.e. oral health promotion, health behaviour models, determinants of oral health, and an epidemiological review of oral health status and behaviours. The book brings out a substantial knowledge in the field of health promotion and its connections. Furthermore, the book assesses oral health and its determinants among Iranian preadolescents, and evaluates a school-based health education program among the children. Professors of oral public health suggest using this well-written and comprehensive book as an educational material in the field. Moreover, the book helps health policy decision-makers to find out and to implement a suitable and feasible oral health intervention program among children. The findings of the book will improve the oral public health practice overall, and specifically in similar countries to Iran.
