简而言之：人们对预防运动中牙齿损伤的兴趣日益增加，导致了对防护设备的更多测试和改进。在这项研究中，硬度，撕裂强度和撕裂能量进行了机器测试，在九个定制的口腔保护材料。由聚醋酸乙烯酯-聚乙烯或硬质聚氨酯制成的四种材料在所有三种性能方面都具有很高的值。两种材料在撕裂能测试期间脱粘。软质聚氨酯和橡胶的所有三种性能的值都很低。用人类受试者和观察者测试透明和彩色口腔保护器的可见性。黄色的护嘴罩，比透明的护嘴罩要近一倍。这些信息可能会使那些必须执行口腔保护规定的官员受益。
In brief: Increased interest in preventing dental injuries in sports has resulted in more testing of and improvement in protective equipment. In this study, hardness, tear strength, and tear energy were machine-tested in nine custom-made mouth-protector materials. Four of the materials made from polyvinyl acetate-polyethylene or hard polyurethane had high values for all three properties. Two materials debonded during the tear energy test. The soft polyurethane and the rubber had low values for all three properties. Visibility of clear and colored mouth protectors was tested with human subjects and observers. Yellow mouth protectors were visible at almost twice the distance of the clear protectors. This information could benefit officials who must enforce mouth-protector regulations.
