牙科塑料材料的不透射线性是理想的。目前，只有不透射线的复合修复材料和一种临时冠材料可在市场上买到。应鼓励在其他牙科聚合物材料中加入不透射线性。此外，应进行研究，以量化和标准化材料及其临床应用的不透射线性。目前，在适用于牙科塑料材料的任何ANSI/ADA规范中均未包含不透射线性要求。然而，已经建立了用于医用塑料的不透射线性的标准测试方法（ASTM标准F640-79）。牙科材料、仪器和设备理事会建议美国国家标准委员会MD 156的相应小组委员会尽快制定要求和适当的测试方法，以纳入牙科塑料标准的未来修订版。
Radiopacity in dental plastic materials is desirable. Currently, only radiopaque composite restorative materials and one temporary crown material are commercially available. Developments in incorporating radiopacity in other dental polymeric materials should be encouraged. Also, research should be conducted to quantify and standardize radiopacity both in materials and their clinical utilization. No requirement of radiopacity is currently included in any ANSI/ADA Specification applicable to dental plastic materials. However, standard test methods (ASTM Standard F640-79) have been established for radiopacity of plastics for medical use. The Council on Dental Materials, Instruments, and Equipment recommends that appropriate subcommittees of the American National Standards Committee MD156 develop, as quickly as possible, requirements and appropriate test methods to be placed in future revisions of standards covering plastics in dentistry.
