The following review of the literature considers various clinical methods for evaluating dental materials. The first section looks at studies that have considered the general handling properties of dental materials in clinical practice (the pragmatic trial). The second section considers studies that have used retrospective evaluation to arrive at conclusions about the longevity of various dental materials (the observational trial). The third section considers the various methods of assessing the quality of restorations in clinical trials (the explanatory trial).
以下文献综述探讨了评估牙科材料的各种临床方法。第一部分着眼于那些在临床实践中考虑牙科材料一般操作特性的研究（实用性试验）。第二部分考量了利用回顾性评估得出各种牙科材料使用寿命结论的研究（观察性试验）。第三部分审视了在临床试验中评估修复体质量的各种方法（解释性试验）。
