The large variety of diagnostic criteria used adds some uncertainty to comparisons of recent clinical and epidemiological data on root caries in Scandinavia. Nevertheless, it is apparent that the prevalence of frank carious cavities on the root among 60(+)-year-olds is about 30-40%. When inactive and recurrent lesions and fillings are included, the prevalence is almost 100% in 60(+)-year-olds. At this age, the mean number of root surface fillings is about 7, and the mean number of active caries lesions ranges from 0.9 to 3.4. The degree of gingival recession does not appear to be a direct measure of root caries risk in a population. When the number of teeth at risk is accounted for, the age-dependent increase in prevalence of root caries is very weak. Therefore, comparisons of root caries prevalence between populations are meaningful only when information on number of teeth present and teeth at risk is also available. Recent studies from various parts of the world have demonstrated that caries is ubiquitous in all populations and that caries progression continues throughout life. The impact of this on trends in prevalence and incidence of dental caries in adults is discussed in the light of what is known about the natural history of dental caries.
在斯堪的纳维亚半岛，用于根龋的诊断标准种类繁多，这给近期根龋临床和流行病学数据的比较增添了一些不确定性。然而，很明显，60岁及以上人群中明显龋洞的患病率约为30%-40%。若将静止性和复发性病变以及补牙算在内，60岁及以上人群的患病率几乎达到100%。在这个年龄段，根面补牙的平均数约为7颗，活动性龋损的平均数在0.9至3.4颗之间。牙龈退缩程度似乎并非衡量人群根龋风险的直接指标。当考虑到患龋风险牙齿数量时，根龋患病率随年龄增长的趋势非常微弱。因此，只有在同时掌握现存牙齿数量和患龋风险牙齿数量信息的情况下，不同人群之间根龋患病率的比较才有意义。世界各地近期的研究表明，龋病在所有人群中都普遍存在，且龋病进展会持续终生。本文根据已知的龋病自然病史，探讨了这一情况对成人龋病患病率和发病率趋势的影响。
