The Effect of Magnesium Oxide Nanoparticles on the Bonding Strength of Soft Denture Liner to the Denture Material
Introduction: One of the most common problems of the soft denture liners is the deboning from the acrylic denture material. Thus, this study evaluates the effect of magnesium oxide nanoparticles (MgO NPs) on the soft liner deboning from the denture material. Materials and methods: In this study, tw...

| description | Introduction: One of the most common problems of the soft denture liners is the deboning from the acrylic denture material. Thus, this study evaluates the effect of magnesium oxide nanoparticles (MgO NPs) on the soft liner deboning from the denture material.
Materials and methods: In this study, two tests were done (Tensile strength and Shear bond strength), for each test two groups were prepared first group (Control, n=5); second group (5 % of MgO NPs impregnated into the soft liner, n=5). Total 40 samples of hot cure acrylic were prepared in dimension of (8.1.2 cm length, width, depth respectively), for tensile bond strength, two acrylic samples where joined vertically with 3 mm thickness soft liner between the two pieces, while for the shear bond strength, two pices of acrylic were joined horizontally with the 3 mm thickness soft liner. The samples placed in distal water for 5 days, Universal testing machine used at crosshead speed of 5 mm/min.
Result: The data showed no statistical difference (Tensile bond strength and Shear bond strength) when 5 % of MgO NPs added into the soft liner. However, when tensile was compared with shear bond strength, higher resistance to tensile was observed compared to the shear strength.
Conclusion: Addition of MgO NPs did not affect the mechanical properties of soft denture liner, accordingly, MgO NPs can be used as antibacterial (as proved by previous studies) without compromising the mechanical properties. |
