Glass Fiber Layer Effect on Chemico-mechanical Properties of Light Cure Adhesive Systems
Abstract
Introduction: Orthodontic adhesives should have clinically acceptable shear and tensile bond strength to withstand masticatory forces and those generated by treatment mechanics. Mechanical properties of the adhesive, such as flexural modulus of elasticity, tensile strength, and compressive strength, are more heavily influenced by the resin matrix's Degree of cure (DC). Aim: The study compares the effect of the Glass fiber layer on Chemico-mechanical properties using three different light cure adhesive systems. Materials and Methods: Three different light cure adhesive systems were used along with everStick® ORTHO glass fiber layer. All the samples were pulverized and prepared in the form of pellets. The Degree of cure was assessed using FTIR. Assessment of shear bond strength was done using 90 first premolar brackets (3M victory series), which were bonded on freshly extracted first premolar teeth using Tans bond XT, Phase II dual-cure and resin modified GIC. Results: The Degree of cure ranges from a minimum of 25.89% in the bracket subgroup of transbond XT to a maximum of 71% in the only adhesive subgroup of Phase II dual cure. There is a significant difference among the subgroups of all the adhesives. Maximum bond strength of 9.8 MPa was observed in the Transbond XT group, and there was no significant decrease in bond strength in Transbond XT (7.6 MPa) even after the introduction of glass fiber layer. Conclusion: It can be inferred that the Glass fiber layer showed a positive effect on the Light cure adhesive system Trans bond XT by increasing the degree of cure, thereby decreasing the cytotoxicity.
