Based upon the present prevalence of root caries an attempt is taken to evaluate the future importance of this carious type. A population sample of 2,261 men and women aged 35 to 74 years were examined. The participation rate was 81%. Root caries was recorded when the lesion was obviously soft and located on cementum. The prevalence of root caries increased for both sexes almost consistently with age and ranged between 49 and 73%. In the mean 1.8 to 2.9 teeth were affected. Root caries was found more often among men than women. Over the sixth decades the reduction of the relative frequency of root caries was stated. Up to this age the rates of tooth extraction were higher than the rates of incidence. If it succeeded that in the future aged people will retain more teeth than nowadays a increase of root caries can be expected.
基于目前根龋的患病率，尝试评估这种龋病类型未来的重要性。对2261名年龄在35至74岁之间的男性和女性进行了抽样检查。参与率为81%。当病变明显发软且位于牙骨质上时记录为根龋。男女根龋患病率几乎都随年龄持续增加，范围在49%至73%之间。平均有1.8至2.9颗牙齿受影响。男性比女性更常发现根龋。在第六个十年期间，根龋相对频率有所下降。到这个年龄，拔牙率高于发病率。如果未来老年人能够比现在保留更多牙齿，预计根龋会增加。
