The work which has monitored caries progression in posterior approximal enamel surfaces by reference to the size of radiolucency seen on bitewing radiographs is reviewed. There are wide variations in the degree of standardisation achieved, in the composition of the study groups and in the duration of the studies. There is a paucity of information relating to adults, the elderly, groups with low caries prevalence, and fluoridated communities. The results indicate that for the majority approximal caries progresses slowly, and large numbers of lesions remain unchanged for long periods. The available results are compared using the mathematical model of a negative exponential. The 'mean' time during which a lesion remains radiographically confined to the enamel is of the order of 3-4 yr, although in caries active individuals much shorter times are reported. Some clinical implications are suggested and the need for further research using comparable methods is stressed.
回顾了通过参考咬合翼片上可见的透射区大小来监测后牙邻面釉质表面龋病进展的研究。在研究的标准化程度、研究组的组成以及研究持续时间方面存在很大差异。关于成年人、老年人、龋病患病率低的群体以及氟化社区的信息匮乏。结果表明，大多数邻面龋进展缓慢，大量病变长期保持不变。使用负指数数学模型对现有结果进行了比较。病变在影像学上局限于釉质的“平均”时间约为3 - 4年，尽管在龋病活跃个体中报告的时间要短得多。提出了一些临床意义，并强调了使用可比方法进行进一步研究的必要性。
