Various types of luting cements are used for fixation in dentistry. Failure through fracture is a significant issue with these materials. Several fracture toughness tests have been developed to characterise dental luting cements. Among them are the Chevron-Notch Short-Rod and Mixed-Mode Sandwich tests. In this study these two techniques are applied to a dental luting cement and from the results of the testing, conclusions are drawn on what they can determine regarding a material's properties.
