Oral health diseases are common in all regions of the world and their impact on anatomical
and social functioning is widely acknowledged.Their distributions are unequal between and within countries, with the greatest burden falling on disadvantaged and socially marginalized populations. The risk factors and social determinants for oral diseases have been comprehensively documented, and the evidence base for their prevention is growing. However, decisions on health care are still often made without a solid grounding in research evidence. Translation of research into policy and practice should be a priority for all. Both community and individual interventions need tailoring to achieve a more equal and person-centered preventive focus and reduce any social gradient in health. The major challenges of the future will be to translate knowledge and experiences in oral disease prevention
and health promotion into action programmes.The international oral health research community needs to engage further in research capacity building and in strengthening the work so that research is recognized as the foundation of oral health policy at global level.
