Profiles of periodontal conditions in older age cohorts, measured by CPITN.

Results of more than 80 CPITN surveys from almost 30 countries for the age groups of 45 years and above are assembled. In this first overview, data for the older age cohorts are presented, showing the percentages of persons according to the highest score per person and the mean numbers of sextants affected per person. Results for three age groups are presented: 45-54, 55-64 and 65-74 years, with two additional surveys in older persons. There were marked variations in periodontal conditions between surveys. The assumed differences between industrialized and non-industrialized countries with regard to periodontal diseases did not show in the data examined. Also, the expected increase in periodontal destruction with increasing age was not reflected in values for pocketing or deep pocketing in the successive age groups. Some variations between surveys was also noted for the rate of tooth loss, expressed in the mean number of excluded CPITN sextants. However, on average, at age 50, almost one sextant was excluded, increasing to 1.5 sextants at 60 and almost 2.5 sextants at age 70. It is therefore suggested that the progress of periodontal destruction with age is not shown in an increase in periodontal CPITN scores, but in increased tooth loss, specified by an increasing number of excluded CPITN sextants. For the age group 65-74 years, this results in, on average, almost half of all sextants being excluded. Of the remaining sextants, approximately half had shallow and/or deep pockets.

Profiles of periodontal conditions in adolescents measured by CPITN.

Results of more than 100 CPITN surveys from over 60 countries for the age group 15-19 years, stored in the WHO Global Oral Data Bank as of 1 August 1990, are assembled. They are presented in the form of graphs showing the mean number of sextants affected per person and arranged by country according to WHO regions. It is hoped that these overviews provide a frame of reference for the evaluation of periodontal conditions in populations and population subgroups. The most frequently observed condition in adolescents was score 2 (calculus with or without bleeding). Calculus seems to be much more prevalent in non-industrialized than in industrialized countries. Although some shallow pocketing of 4 or 5 mm was present in two-thirds of all populations observed, it affected mostly only a minority of the sample and then only in one or two sextants. However, a few surveys showed a relatively high prevalence of pocketing. As the surveys were carried out in adolescents, such high figures indicate serious problems ahead.

Profiles of periodontal conditions in adults measured by CPITN.

Results of almost 100 CPITN surveys in more than 50 countries for the age group 35-44 years, stored in the WHO Global Oral Data Bank as of 1 August 1990, are assembled. They are presented in the form of graphs showing the percentages of persons according to the highest score per person and arranged by country according to WHO regions. It is hoped that these overviews provide a frame of reference for the evaluation of periodontal conditions in populations and population subgroups. Calculus and shallow pocketing were the most frequently observed conditions. With a few exceptions, the percentages of persons and the mean number of sextants per person with deep pockets were small to very small. The assumed differences between industrialized and non-industrialized countries with regard to periodontal health were not reflected in the survey data examined. Severe periodontal destruction seems to be a limited problem, seldom leading to tooth loss before the age of 50. For the large majority in most of the populations observed, the progress of periodontal diseases seems to be compatible with the retention of a natural dentition into older age. Nevertheless, the periodontal problem is of considerable magnitude and importance, as 5-20 per cent of populations are affected by a serious, irreversible condition at the age of 40, which is a high percentage compared with almost every other disease that afflicts mankind.

Value of technology assessment in developing countries.

The contrasting cycles of changing caries prevalence in developing and industrialized countries are described, as they relate to differing needs in technology. Using this contrast as a background, the selective needs for technology in measurement, adequate quality of treatment and materials, appropriate personnel, and simplicity and mobility in equipment are discussed.

International collaborative studies in oral health: a practical illustration of WHO research policy.

The International Collaborative Study (ICS) initiated by the World Health Organization (WHO) and supported by the United States Public Health Service is a meaningful practical example of international scientific collaboration. It involves 12 study sites within eight different countries. The main objective embodied in the global strategy of WHO is to focus on action for the better health of all people. The ultimate purpose of the project is to improve the effectiveness and efficiency of oral health care systems by providing policy makers and researchers with detailed, reliable and valid data on the oral health situation in their country together with comparative data from other countries' oral health care systems. The ICS I (1973-1981) is described and the main outcomes are discussed with regard to their impact on national health policies. The ICS II which was launched in February 1988 and is currently ongoing is presented. Differences and similarities between the two projects are discussed as well as the main expected achievements.

The fluoride content of selected foods in relation to the fluoride concentration of water.

The F content of foods and beverages comprising a substantial proportion of the Hungarian diet has been determined. Vegetables and fruits grown in three areas where the mean F content of water was 0.09 mg/l, 0.81 mg/l and 1.91 mg/l did not reflect these differences. In contrast, the F content of cooking water has made demonstrable contribution to the F content of cooked foods. Significant elevation in F concentration was also found in some meat products, where the inclusion of bone dust or fragments is suggested by corresponding increase in Ca content.

Daily fluoride intake from the diet of Hungarian children in fluoride deficient and naturally fluoridated areas.

Average daily dietary intakes of F were determined for 67 kindergarten children (X age 3.9 years) and 118 schoolchildren (X age 14.0 years), resident in one of three areas where the concentration of naturally occurring F in the household water ranged 0.06-0.11 mg/l, 0.05-1.10 mg/l and 1.6-3.1 mg/l. Mean daily F intakes increased consistently and significantly with increasing F content of the water in all dietary categories in both age groups. Due to relatively low water and high milk consumption, F from foods has made a greater contribution to total F intake (40-53% over the whole sample) than F in water ingested as such, or in beverages. The total amount of F ingested from dietary sources is considered safe even at the highest intake levels found (X = 0.44 mg/day, SD = 0.11 at 3.9 years; 1.49 mg/day, SD = 0.35 at 14.0 years).

Aluminium, calcium and magnesium content of Hungarian foods and dietary intakes by children aged 3.9 and 14 years.

The Al, Ca and Mg content of 147 kinds of foods and beverages, representing a large proportion of the Hungarian diet, has been determined using replicate samples. Dietary intakes of these minerals by 67 kindergarten children and 139 schoolchildren have been assessed. The richest sources of Al were: parsley, celery, gherkins, barley-malt; of Ca: dairy products, celery, parsley, savoy; of Mg: dried beans and peas, parsley, dill, maize-flour, rice, gherkins, chocolate. Flavouring agents (e.g. salt, pepper, paprika, caraway-seed) had very high concentrations of all three minerals and poppy-seeds that of Ca and Mg. The presence of bone-dust or fragments elevated the Ca content of some meats and cooked dishes. The main source of dietary intake of all three minerals was food; as opposed to F, the contribution of water-borne Al, Ca and Mg was negligible. Based on average values, the daily intake of all three minerals was satisfactory in both age groups. Mg intake was marginally below the recommended limit for a few children, but no signs of Mg deficiency were seen.

Fluoride intake and utilization by Hungarian children: associations and interrelationships.

Selected interactions were examined between F, Al, Ca and Mg intakes and their manifestations in dental health parameters and biological samples relating to Hungarian children. The prevalence (DMFT, DMFS) and severity (SR) of caries were inversely related to the F concentration of household water and to the amount of F ingested from foods, beverages and tap or well water. Dental fluorosis and the F content of enamel, plaque, saliva, urine, nails and hair were directly related to the F content of water and to dietary F intake. The high significance levels and absolute consistency of associations lend strong support to the biological interdependence of the variables involved. In contrast, no associations were found between Mg ingestion and F utilization. Despite numerous inverse trends and some statistically significant inverse associations suggesting that dietary Al and Ca interfere with F uptake, the biological significance of the latter findings needs further exploration. Inhaled F amounted to less than 0.17% of the total F intake. The F content of frequently prescribed non-dental medicines ranged from below 0.00001 to 0.014 mg/g; their contribution to total F intake is considered insignificant.

Periodontal conditions in adults, 35-44 years of age: an overview of CPITN data in the Who Global Oral Data Bank.

Results of 28 CPITN surveys in 24 countries for the age group 35-44 years, stored in the WHO Global Oral Data Bank as of 1 July 1986 are assembled in an overview presenting: percentages of persons according to the highest score for each person, the estimated national percentages of edentulousness and the mean numbers of sextants affected per person. It is concluded that for a large majority in most of the populations observed, the progress of periodontal disease has been slow and seems to be compatible with retention of a natural dentition until at least the age of 50.

Needs and implementation of preventive dentistry in China.

Based on a literature review and recent surveys, the needs and implementation of preventive dentistry in China have been estimated. The average DMFT of 12- and 15-yr-old schoolchildren in Beijing were 1.61 and 2.11 respectively. The caries prevalence was higher in the coastal cities in the south. The caries rate was also higher in urban areas than in rural areas. There were some controversies in the results of fluoridation studies with one study reporting as high as 47.2% of the children to be afflicted with enamel fluorosis. The community periodontal disease status and treatment needs index (CPTNI) showed that 93% of the 12-yr-olds had bleeding, 98% had calculus and 15% had shallow pockets, with 100% of the children needing prophylaxis. There was a high prevalence of dental malocclusion with 54% of schoolchildren with dental anomalies, of whom 36% needed treatment. Much emphasis had been placed on oral pathology, oral medicine and maxillofacial surgery in the curriculum of Stomatology in Chinese dental schools.
