 note = {application/pdf, Various types of cementing materials were subjected to thermocycling (between 4℃ and 60℃ for 1,000, 3,000, and 10,000 cycles) and storage in 37℃ in water for equivalent duration to the total thermocycling time. These samples were then subjected to bend strength and fracture strain tests. Fractographic studies were also conducted on fractured surafecs. The main results obtained are as follows; 1. Bend strengths of LC, HG, EC and FL sample groups increased even after 10,000-cycled thermocycling treatment. On the other hand, LM sample group showed a decrease in bend strengths. 2. Bend strengths of LC, HG, EC, FL and LM sample groups which were stored in 37℃ water for 375 hours were higher than those of the 24-hours storage in 37℃ water. 3. Fracture strain of LC, HG, EC, FL and LM sample groups thermocycled for 10,000 cycles decreased. Similar result was obtained for same sample groups which were stored in 37℃ water for 375 hours. 4. With fractured surfaces of LC, HG, and EC sample groups, spherical cavities were observed, suggesting that reaction gas was entrapped.},
