The study has demonstrated a high prevalence of dental caries and a uniformly high level of treatment across all major population groups of Canterbury 13-14 year olds. The treatment programme has the problem of dental caries under control but more attention should be directed to lowering caries prevalence and the need for treatment by increased use of preventive measures. While increasing the population coverage in respect of fluoridated water would give the greatest reduction in caries prevalence, alternatives should be considered, especially in areas not served by piped water supplies. As dental personnel appear to be important sources of health education information, advantage should be taken of this opportunity to emphasize the importance of preventive care. The early signs of periodontal disease are of concern and they, too, should be susceptible to a more concerted preventive programme. Previous studies have demonstrated a high prevalence of denture wearers amongst New Zealand adults. This, and these early results from the International Collaborative Study have focussed attention on the need for information on factors influencing the demand for treatment once adolescents have reached the maximum age covered by the Government programmes. Further investigation is needed to provide these data.
