Faulty bond strength measurements?

February 26th 2020

 -

The most commonly used bonding stress method for testing adhesives and cement, the thermal cycling, jeopardizes the results if not done with caution. This leads to a more favorable bond strength than the true value.

Temperature Changes in Test Specimens During Thermal Cycling

July 23rd 2018

 -

Abstract Objectives Thermal cycling procedure using water bath of 5 C and 55 C is a commonly used method to stress and age test specimens in laboratory testing. Typically, test specimens are kept in each of the water bath for 20 sec with 3 sec transfer time using 5000 – 10 000 cycles. After the […]
Improved micro-tensile strength test reveals key to successful repair of restorations
