African countries propose a regional oral health strategy: The Dakar Report from 1998.

It is clear that the African region faces a number of serious oral diseases, either because of their high prevalence or because of the severe tissue damage or death that can occur. Previous approaches to oral health in Africa have failed to recognise the epidemiological priorities of the region or to identify reliable and appropriate strategies to assess them. Efforts have consisted of an unplanned, ad hoc and spasmodic evolution of curative oral health services. This document focuses on the most severe oral problems that people have to live with like noma, oral cancer and the oral consequences of HIV/AIDS infection. It proposes a strategy for assisting member states and partners to identify priorities and interventions at various levels of the health system, particularly at the district level. The strategy aims at strengthening the capacity of countries to improve community oral health by effectively using proven interventions to address specific oral health needs. The strategy identifies five main 'programmatic areas', including (i) the development of national oral health strategies and implementation plans, (ii) integration of oral health in other programmes, (iii) delivery of effective and safe oral health services, (iv) regional approach to education and training for oral health, and (v) development of effective oral health management information systems. Many of the programmatic areas share similar characteristics described as a 'strategic orientation'. These strategic orientations give effect to the concepts of advocacy, equity, quality, partnership, operational research, communication and capacity building. The WHO Regional Committee for Africa (RC) is invited to review the proposed oral health strategy for the African region for the period 1999-2008 and provide an orientation for the improvement of oral health in member states in the region.

Oral diseases and socio-economic status (SES).

OBJECTIVE: To determine the association between social, economic and behavioural risk factors and national prevalences of: oral cancer, dental caries (12-year-olds) and destructive periodontal disease (35-44-year-olds). DATA SOURCES: Sources for the social and economic parameters were the UN Development Program; the behavioural risk factors' source was the World Health Organization, the UN Food and Agricultural Organization and the World Atlas of History. Oral diseases data came from UICC Globocan and the World Health Organization databases. DATA EXTRACTION: Data were extracted by hand from official publications. DATA SYNTHESIS: Data were synthesized and analyzed in sequence using SPSS, Pearson's correlation coefficient and multiple regression analyses. CONCLUSIONS: There is a discernable association between the three oral diseases and the variables selected, which varies in strength, being strongest for chronic destructive periodontitis and weakest for oral cancer. Dental caries lies in between. The degree to which variables account for differences in the three oral diseases between the countries studied is striking, being insignificant for oral cancer incidence, modest for oral cancer mortality, stronger for dental caries and strongest for destructive periodontal disease. Removing variables with strong co-linearity with the Human Development Index has little effect on the regression coefficients.

Economic globalization and oral health.

OBJECTIVES: To briefly review the origins of economic globalization and examine the evidence available concerning its possible impact on oral health. DESIGN: Based on Medline searches 1966-1999 and review of Health Wrights: Politics of Health database. SPECIFIC ORAL DISEASES: Dental caries, destructive periodontal diseases, cancrum oris and oral cancer. CONCLUSIONS: The reported growing disparity between rich and poor populations, both internationally and nationally, is arguably being exacerbated by economic globalization. Increasing levels of the above specific oral diseases might be attributed, in part, to this economic phenomenon.

Context as a critical influence on dental education.

The problems which beset dental education in many African countries are not unique to the African continent. While modified by the continent's history and present stage of development many of the difficulties are similar to those in developing and industrialised countries throughout the world. The need for oral health education programmes to produce, in the most cost-efficient manner, competent, high-quality graduates capable of coping in diverse situations is universal. This article reviews the limitations that the local context places on achieving these dual objectives and highlights the significance of the role of consumer demand for dental care in creating viable dental education programmes, particularly in poorer countries.

Setting global goals for oral health for the year 2010.

OBJECTIVE: To discuss the determinants for the possible setting of global goals for oral health for the year 2010. RESULTS AND CONCLUSIONS: If the application of oral health goals is to measure the outcome of oral health strategies and plans, they need to be substantially redesigned to reflect disparities in oral health and access to oral health care. It is no longer acceptable to focus only upon one or two arbitrarily selected disease entities and say these reflect the oral well-being of communities and the success (or failure) of oral health programmes. The use of validated socio-dental indicators to assess prevalence of socio-dental impacts seems essential, as does the avoidance of goals for conditions that are strongly influenced by culture, class, ethnicity and other widely variable local influences.

Dental caries, socio-economic development and national oral health policies.

A relationship between a population's level of socio-economic development and dental caries has often been assumed. Proxy measures such as sugar consumption have been used to reflect this. This study tests the hypothesis that there is a relationship between dental caries and the level of socio-economic development, using recent international data. It goes on to explore the implications of this relationship for the development of national oral health policies. Dental caries data was obtained from the WHO, Global Oral Epidemiology Data Bank for the period 1981-1996. Socio-economic data was obtained from the United Nations Development Programme (UNDP). Countries were ranked according to the Human Development Index (HDI) and their GNP. The study confirms the existence of a relationship between dental caries and development. Caries is a good proxy measure for socio-economic development. Countries in the throes of socio-economic transition have the highest DMFT scores.

Dental caries status of 5-7 year old children in three districts in Tanzania, Uganda and Mozambique.

This paper presents the baseline data of a longitudinal study assessing the dental caries status of 5-7 year old children in Tanzania, Uganda and Mozambique. Approximately one hundred 5-7 year-old-children from randomly selected schools in each of three locations (formal urban, informal urban and rural) were examined using the 1997 WHO Oral Health Survey Criteria. Thirty nine percent of the entire sample were found to bc caries-free, however this differed from location to location and from country to country. The overall mean dmft was 2.4 (SD 2.8), with the decayed component being 2.0 and the missing component 0.4. Of the children examined, only three had filled teeth. The mean dmft was significantly higher (p-value < 0.05) in Tanzania and Uganda than in Mozambique. There were also significant differences in the mean dmft between the various locations in Uganda and Mozambique. The prevalence of dental caries was not consistent across the formal urban, informal urban and rural locations in the three countries studied. It is thus essential to desegregate oral health status data to the most local level possible.

Developing appropriate dental education systems: the impact of changes in oral health status and oral health care systems.

Current education programmes for oral health care workers have failed to adapt to the changing oral health status and the changing demands made upon oral health care systems. In order to adapt, education systems need to recognise the forces that are influencing the demands on the oral health care system and identify the most appropriate solutions. The most logical solution is to develop programmes which reflect the Primary Health Care Approach (PHCA), and in particular emphasise inter-sectorial collaboration. The challenge for dental education systems is to identify mechanisms through which these principles can be applied.

Oral disease in Africa: a challenge to change oral health priorities.

Colonial and other unsustainable oral health strategies exported to Africa have failed to improve oral health in the region. An alternative way of interpreting and responding to the problems of oral health in Africa is presented. It begins with a systematic interpretation of the health information available, using the application of the basic epidemiological principle of defining a specific health problem by describing its prevalence, severity (morbidity, mortality) and age adjusted distribution in the population. African oral disease priorities determined in this way are shown to be fundamentally different from those perceived previously. It is recommended that this new approach be used in customising a viable set of oral health policies and intervention strategies for each individual African community.

Health as a fundamental human right.

Access to health care is problematic for many people throughout the world, and the environments in which they live are often detrimental to their health. Recognising health as a human right provides a platform from which to argue for strong public health programmes.

A magnetic resonance imaging study of centric maxillomandibular relation.

The authors conducted research to determine the structural relationships of the craniomandibular articulation that resulted when a mandibular reference position was established. A noninvasive clinical method was used to identify and record centric maxillomandibular relation in normal subjects and a suitable reference position in subjects with derangements of the craniomandibular articulation. The reference positions were checked for repeatability. Magnetic resonance imaging was used to determine the intraarticular relationships resulting from application of the clinical techniques. The normal subjects conformed well to the 1987 "Glossary of Prosthodontic Terms" definition, with the mandible close to first-tooth contact. In subjects with deranged articulations, the condyle was always in an abnormal relationship on the affected side in the reference position, and there were many intersubject variations.

Medicine in a muddle?

I believe that medicine is currently in a muddle and like a magician lost in a maze of caves and tunnels, is trying to get out of the muddle by creating ever stronger magic potions and spells. The magic opens new tunnels, but does not create an opening out into the fresh air. Or so it seemed to me when, as a new professor of dentistry. I had to think about my vision of the future of dentistry in South Africa.

The Kilkenny Integrated Oral Health Project.

The Kilkenny Health Project, started in 1985, aims to reduce the level of risk factors in the community for coronary heart disease through health promotion. Dental disease and coronary heart disease share risk factors of tobacco use, alcohol consumption and poor dietary patterns. A baseline oral health survey demonstrated significant levels of dental disease in Kilkenny in the 429 adults and 523 children who were examined there in 1987. Seventy one per cent of adults required treatment for periodontal disease and 49% of children surveyed required treatment for dental decay. The Kilkenny Oral Health Project was developed as a community participation project aiming to reduce the level of common risk factors in the community for coronary heart disease and dental disease. It has run parallel with the main Kilkenny Health Project and is one of the first health promotion projects which has an integrated health message preventing dental disease and coronary heart disease.

Public water fluoridation in Ireland: twenty-five years on.

In July of this year, 1989, Ireland celebrates 25 years of fluoridation of the public water supplies. No other country has had such a long experience of a national mandatory public water supply fluoridation programme. There is good reason therefore to review experiences and attempt to draw some conclusions.
