The melting points of MCPM and DCPD, estimated by differentialthermal analysis, are971℃ and1348℃ , respectively; thus the melting point of MCPM was lower than that ofDCPD. When heated, MCPM decomposed to γ-metacalcium phosphate, β-metacalcium phosphate and δ-metacalciumphosphate. On the other hand, DCPD changed to DCPA, γ-calcium pyrophosphate, β-calcium pyrophosphate and α-calcium pyrophosphate. Solubility in200 mM acetic acid buffer was higher with heated MCPM than with heatedDCPD samples. This leads us to conclude that DCPD would be more effective as a sealant material than MCPM.Comparison of lased disks made of MCPM and DCPD at various energy densities showed that with DCPD disks, fewercraters were formed, and no craters were formed at an energy density of45.6 J/cm^2. All these findings suggest thatDCPD would have advantages over MCPM as a sealant that can be fused at a lower energy density with no damage onthe enamel surface.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6861","nameIdentifierScheme":"WEKO"}],"names":[{"name":"GOTO,
