In an in vitro experiment, the failure loads of 59 intact endodontically treated teeth with and without Kerr Endo-Post reinforcement were compared. Fifty-eight teeth fractured below the cementoenamel junction. One tooth fractured through the pulp chamber with a chisel fracture involving both the crown and root. Teeth without posts fractured through the middle or coronal one third of the root. Teeth with posts fractured through the body of the post. No statistically significant reinforcement was demonstrated by cementing a Kerr Endo-Post No. 100 into a sound endodontically treated tooth.
在一项体外实验中，对59颗完整的经根管治疗的牙齿在有或没有 Kerr Endo-Post 增强的情况下的破坏载荷进行了比较。58颗牙齿在牙骨质牙釉质界下方折断。一颗牙齿通过牙髓腔折断，呈凿状骨折，累及冠部和根部。未使用桩的牙齿在牙根中部或冠方三分之一处折断。使用桩的牙齿在桩体处折断。将100号 Kerr Endo-Post 粘结到完好的经根管治疗的牙齿中，未显示出统计学上显著的增强效果。
