In 1948 the World Health Organization defined oral health as “a complete state of physical, mental, and social well-being, and not just the absence of infirmity.”
World Health Organization (WHO). Constitution of the World Health Organization. Geneva: WHO Basic Documents; 1948.
Physical well–being assumes the ability to function normally in activities such as speaking, eating, and moving around.
Mental well–being implies that there is no burden of fear, anxiety, stress, depression, or other negative emotions.
Social wellbeing relates to one’s ability to participate in society, fulfilling roles and duties.
World Health Organization (WHO). Constitution of the World Health Organization. Geneva: WHO Basic Documents; 1948.
Oral health is fundamental to overall health, wellbeing and quality of life. A healthy mouth enables people to eat, speak, work and socialize without pain, discomfort or embarrassment.
Healthy Mouths, Healthy Lives: Australia’s National Oral Health Plan 2004–13 (2004). Prepared by the National Advisory Committee on Oral Health.
“The mouth is the gateway to the rest of the body, a mirror of our overall well-being.”Along this, oral health must be perceived as a critical component of general health.
Harold C. Slavkin, D.D.S. Former Director of the National Institute of Dental and Craniofacial Research, and Dean of the University of Southern California School of Dentistry
Dental disease negatively impacts general quality of life, affecting not only physical wellbeing but also psychological and social wellbeing.

Oral health problems can affect a person's ability to maintain a job or get promotions. They can also contribute to lowered academic achievement and goals. These effects have increased when a deformity due to the oral health condition is involved

Children face the additional challenge of poor oral health far reaching effects into their adulthood. Dental conditions in childhood can restrict children’s participation in schooling and education through days lost to illness. Impaired physical appearance due to dental disease can further limit children’s ability to socialize with confidence and develop social norms and relationships.
Tooth decay is the most common chronic childhood disease affecting 60 90% of school children.‑
It is over five times more prevalent than asthma among children.
7 times more common than hay fever. 52 million school hours missed annually because of oral problems

There are profound inequalities in caries status, between countries, and that the distribution of disease in a population is a changing dynamic.
Marmot, M. and Wilkinson, R. (1999), Social determinants of health, Oxford University Press, Oxford.
Health inequalities are the systematic, structural differences in health status between and within social groups within the population.
The term ‘‘health inequalities’’ is closely linked to ‘‘social determinants of health’’.
Lack of income, schools, and education, inappropriate housing, unsafe workplaces and lack of access to health care systems are some of the social determinants of health leading to inequalities.

“ You cannot educate a child who is not healthy, and you cannot keep a child healthy who is not educated.”
Jocelyn Elders, Former US Surgeon General
Health education is any combination of learning experiences designed to facilitate voluntary actions conducive to health.
Integration of oral health into the school curriculum
In recent years, attention has been drawn toward assessing the effectiveness of oral health education programs. This is in line with demand for evidence based research and will help to inform policy makers on how to allocate resources.
Evidence based papersEvidence based papers
Google, Google Scholar, the Cochrane Library MEDLINE and EMBASE electronic databases were searched as well as hand searching of found references and review articles.
The strength of the evidence to support each intervention is indicated using the modified Davies et al 2003 hierarchy:
Type 1 Systematic review Type 2 At least one RCT Type 3 Non-randomised intervention studies Type 4 Observational studies.

Cooper et al., 2013
To assess the clinical effects of school-based interventions aimed at changing behavior related to tooth brushing habits and the frequencyof consumption of cariogenic food and drink in children (4 to 12 year olds) for caries prevention.
Type 1systematic review of studiespublished between 1950 to 2012.
Currently, there is insufficient evidence for the efficacy of primary school-based behavioral interventions for reducing caries. There islimited evidence for the effectiveness of these interventions on plaque outcomes and on children’s oral health knowledge gain.

A number of systematic reviews have been conducted on the available evidence for the effectiveness of school-based
behavioral interventions . These have shown that oral health education can be effective in increasing knowledge in the short term and to some extent, behavior such as tooth brushing and healthy eating. However there is a limited
evidence for its effectiveness on children’s oral health in terms of reducing dental plaque and dental caries.
Comments about the findings
Oral diseases are multifactorial.
Dahlgren and Whitehead, 1993

The Ottawa Charter defines health promotion as ‘the
process of enabling people to increase control over,
and to improve, their health’.

Basic logic: Can school-based interventions aimed at improving health status
works?.........
Health education interventions are of limited value and should be supported by a full range of health promotion
approaches.Multiple interventions that complement and reinforce each
other, and involve a range of community partners and stakeholders may be more effective than single
interventions.
Link to the home by actively involve parents in school interventions Provide support for teachers or use non-teacher supervisors Employ oral health professionals to provide support for Health
Promoting Schools approaches, rather than only provide classroom lessons
Involve private dental providers in planning for greater cooperation
Integration with other health issues enhances the likelihood of sustainability.
Long-term school support is needed.
Simpson in 2011 provides a promising multi-stage model based on four stages: training, adoption, implementation and practice improvement, along with sustaining influences involving preparation and maintenance.

Address the broader determinants of health.
Focusing on these determinants is the key
to preventing disease and to propose strategies for overcoming inequalities in
oral health.
