ABSTRACT
Objectives: The aim of this study was to evaluate the shear bond strength and failure pattern of ormocer- based restorative material bonded to tooth structure [enamel and dentin ] using ormocer-based adhesive to be compared with non-specific resin-based adhesives [3-fifth and 1-six generation adhesive resins]
Methods: Seventy non-carious human molars were prepared to obtain 35 molars with Hat buccal enamel surfaces and 35 molars with flat occlusal dentin surfaces. The following adhesive systems were applied to both the prepared enamel and dentin surfaces [1] Admira Bond, specific ormocer adhesive system, [2] Prime and Bond NT, [3] Excite, [4] AdheSE and [5] Prompt-L-Pop non-specific resin-based adhesive systems. Ormocer filling material [Admira ] was inserted in a teflon mold of 4mm in diameter and height onto the prepared tooth surface and cured with halogen light curing unit. The shear bond strength was measured using universal testing machine
Results: The greatest bond strength was recorded for the specific Admira Bond adhesive system and non-specific adhesive systems, total- etch [Prime and Bond NT and Excite]. Self-etching, non-specific adhesive systems [AdheSE and Prompt-L-Pop] recorded the lowest bond strength Values
Conclusion: Total etch, non-specific bonding agents can be used with Admira, ormocer-based filling material.e.g Prime and Bond NT and Excite
