The burden of oral disease: challenges to improving oral health in the 21st century.

Abstract: Dental caries and periodontal diseases have historically been considered the most important part of the global burden of oral diseases. At present, the distribution and severity of oral diseases vary in different parts of the world and within the same country or region. Dental caries is still a major public health problem in most industrialized countries, affecting 60-90% of schoolchildren and the vast majority of adults. It is also a prevalent oral disease in several Asian and Latin American countries, while it appears to be less common and less severe in most African countries. It is expected, however, that the incidence of dental caries will increase in the near future in many developing countries of Africa, as a result of growing consumption of sugars and inadequate exposure to fluorides. The significant role of socio-behavioural and environmental factors in oral disease and health is demonstrated in a large number of epidemiological surveys. The current pattern of dental caries reflects primarily distinct risk profiles across countries (related to living conditions, lifestyles and environmental factors) and the implementation of preventive oral health systems. In some industrialized countries there has been a positive trend in the reduction of tooth loss among adults in recent years, though the proportion of edentulous persons in the elderly population is still high in some countries. In most developing countries, access to oral health services is limited and teeth are often left untreated or are extracted because of pain or discomfort. Tooth loss and impaired oral function are therefore expected to increase as a public health problem in many developing countries. Tooth loss in adult life may also be attributable to poor periodontal health. Severe periodontitis, which may result in tooth loss, is found in 5-15% of most populations. In industrialized countries, studies show that tobacco use is a major risk factor for adult periodontal disease. With the growing consumption of tobacco in many developing countries, the risk of periodontal disease and tooth loss may therefore increase. Oral cancer is closely related to the use of tobacco and excessive consumption of alcohol. The prevalence of oral cancer is particularly high among men, and is the eighth most common cancer worldwide. In south and central Asia, consumption of tobacco in various forms is particularly high, and cancer of the oral cavity ranks among the three most common types of cancer. Periodontal disease and tooth loss are also related to chronic diseases such as diabetes mellitus: the growing incidence of diabetes may further impact negatively on oral health of people in several developing countries. …

The World Oral Health Report 2003: continuous improvement of oral health in the 21st century – the approach of the WHO Global Oral Health Programme

Abstract: Chronic diseases and injuries are the leading health problems in all but a few parts of the world. The rapidly changing disease patterns throughout the world are closely linked to changing lifestyles, which include diets rich in sugars, widespread use of tobacco, and increased consumption of alcohol. In addition to socio-environmental determinants, oral disease is highly related to these lifestyle factors, which are risks to most chronic diseases as well as protective factors such as appropriate exposure to fluoride and good oral hygiene. Oral diseases qualify as major public health problems owing to their high prevalence and incidence in all regions of the world, and as for all diseases, the greatest burden of oral diseases is on disadvantaged and socially marginalized populations. The severe impact in terms of pain and suffering, impairment of function and effect on quality of life must also be considered. Traditional treatment of oral diseases is extremely costly in several industrialized countries, and not feasible in most low-income and middle-income countries. The WHO Global Strategy for Prevention and Control of Noncommunicable Diseases, added to the common risk factor approach is a new strategy for managing prevention and control of oral diseases. The WHO Oral Health Programme has also strengthened its work for improved oral health globally through links with other technical programmes within the Department for Noncommunicable Disease Prevention and Health Promotion. The current oral health situation and development trends at global level are described and WHO strategies and approaches for better oral health in the 21st century are outlined.

The global burden of oral diseases and risks to oral health

Abstract: This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed. The challenges of improving oral health are particularly great in developing countries.

Improving the oral health of older people: the approach of the WHO Global Oral Health Programme

Abstract: The proportion of older people continues to grow worldwide, especially in developing countries. Non-communicable diseases are fast becoming the leading causes of disability and mortality, and in coming decades health and social policy-makers will face tremendous challenges posed by the rapidly changing burden of chronic diseases in old age. Chronic disease and most oral diseases share common risk factors. Globally, poor oral health amongst older people has been particularly evident in high levels of tooth loss, dental caries experience, and the prevalence rates of periodontal disease, xerostomia and oral precancer/cancer. The negative impact of poor oral conditions on the quality of life of older adults is an important public health issue, which must be addressed by policy-makers. The means for strengthening oral health programme implementation are available; the major challenge is therefore to translate knowledge into action programmes for the oral health of older people. The World Health Organization recommends that countries adopt certain strategies for improving the oral health of the elderly. National health authorities should develop policies and measurable goals and targets for oral health. National public health programmes should incorporate oral health promotion and disease prevention based on the common risk factors approach. Control of oral disease and illness in older adults should be strengthened through organization of affordable oral health services, which meet their needs. The needs for care are highest among disadvantaged, vulnerable groups in both developed and developing countries. In developing countries the challenges to provision of primary oral health care are particularly high because of a shortage of dental manpower. In developed countries reorientation of oral health services towards prevention should consider oral care needs of older people. Education and continuous training must ensure that oral health care providers have skills in and a profound understanding of the biomedical and psychosocial aspects of care for older people. Research for better oral health should not just focus on the biomedical and clinical aspects of oral health care; public health research needs to be strengthened particularly in developing countries. Operational research and efforts to translate science into practice are to be encouraged. WHO supports national capacity building in the oral health of older people through intercountry and interregional exchange of experiences.

The Theory of Planned Behaviour

Abstract: The theory of Planned Behaviour is one of the models most frequently used in the literature to explore pro-environmental behaviour including recycling, travel mode choice, energy consumption, water conservation, food choice, and ethical investment (Stern, 2000; Staats, 2003). Armitage and Conner (2001) identified its application in 154 different contexts. The Theory of Planned Behaviour (Ajzen, 1988) assumes that the best prediction of behaviour is given by asking people if they are intending to behave in a certain way. Here we note that the intention will not express itself in behaviour if it is physically impossible to perform the behaviour or if unexpected barriers stand in the way. Assuming intention can explain behaviour, how can intention be explained?. According to Azjen, three determinants explain behavioural intention: 1. The attitude (opinions of oneself about the behaviour); 2. The subjective norm (opinions of others about the behaviour); 3. The perceived behavioural control (self-efficacy towards the behaviour).
