The aim of this paper was to describe what experts of today believe are the main reasons explaining the caries decline seen in many westernized countries over the past 3 decades. We have collected the views of a number of international experts, trying to answer the specific question "What are the main reasons why 20-25-year-old persons have less caries nowadays, compared to 30 years ago?". A questionnaire was mailed to 55 experts with a number of thinkable explanations to be scored according to a predetermined scale. The 25 items were divided into main groups under the heading of diet, fluorides, plaque, saliva, dentist/dental materials and other factors. The experts were asked to think of a specific country or area, and also to specify whether the chosen area had water fluoridation or not. The main finding of our study, based on a 95% response rate, was that there is a very large variation in how the experts graded the impact of various possible factors. For the use of fluoride toothpaste, there was a clear agreement of a definite positive effect.
本文的目的是描述当今专家们认为导致过去30年许多西方国家龋齿率下降的主要原因。我们收集了多位国际专家的观点，试图回答“与30年前相比，20至25岁人群如今龋齿较少的主要原因是什么？”这一具体问题。一份包含若干可想到的解释的问卷被寄给了55位专家，这些解释需根据预定的量表进行评分。这25个项目被分为饮食、氟化物、牙菌斑、唾液、牙医/牙科材料及其他因素等主要类别。专家们被要求考虑一个特定的国家或地区，并指明所选地区是否有自来水加氟。基于95%的回复率，我们研究的主要发现是，专家们对各种可能因素影响的评分存在很大差异。对于含氟牙膏的使用，存在明确的一致看法，即有肯定的积极效果。
