ABSTRACT
For many years the Oral Health Programme of the World Health Organization has promoted the development of oral health epidemiological surveys. The objective of this article is to make oral health researchers aware of the variables and statistical tables recommended by WHO for the standardization, presentation and comparability of international surveys. The influence of the growing impact of computer technology in providing better knowledge of oral health systems is also discussed in this article.

Results of 61 CPITN surveys in 39 countries for the age group 15-19 yr, stored in the WHO Global Oral Data Bank as of 1 July 1987, are assembled in an overview showing percentages of persons according to the highest score for each person and the mean numbers of sextants affected per person. The most frequently observed condition was score 2 (calculus with or without bleeding), although some shallow pocketing of 4 or 5 mm was present in most populations surveyed. It should thus be emphasized that the major thrust of activities in periodontal care should be in health promotion and education, leading to improved oral hygiene.

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.
