Criteria for the evaluation of the physical and chemical properties of dental materials have been available for many years. However, the final decision about the acceptability of a dental restorative material for use in the mouth can only come from clinical observation. This paper attempts to set out a systematic approach to the clinical assessment of restorative materials by posing a series of questions, to each of which an answer Yes or No can be given. The system makes provision for reaching decisions on marginal adaptation, restoration and preservation of anatomic form, protection against recurrence caries, and in the case of materials used in anterior restorations, colour match and cavo surface margin discoloration. Using these criteria, restorations can be classified into four categories: those within a range of excellence, those which although showing minor deviations from the ideal are nevertheless acceptable, those which should be replaced for preventive reasons to avoid the likelihood of future damage and those which require immediate replacement.
评估牙科材料物理和化学性质的标准已经存在多年。然而，关于一种牙科修复材料能否用于口腔的最终决定只能来自临床观察。本文试图通过提出一系列问题，给出是或否的答案，从而阐述一种系统的修复材料临床评估方法。该系统为在边缘适应性、解剖形态的恢复和保存、预防继发龋以及在前牙修复中使用的材料的颜色匹配和洞缘变色等方面做出决策提供了依据。使用这些标准，修复体可分为四类：卓越范围内的修复体、虽与理想情况有轻微偏差但仍可接受的修复体、因预防原因应更换以避免未来损坏可能性的修复体以及需要立即更换的修复体。
