ค่ากำลังแรงยึดดึงของเรซินซีเมนต์สามระบบกับเนื้อฟันที่ผ่านการแช่โซเดียมไฮโปคลอไรท์ / อรุณรัตน์ มุจจลินท์วิมุติ = Tensile bond strength of three resin cement systems to dentin immersed in sodium hypochlorite / Arunrat Mujjalinvimut
The objective of this study is to evaluate microtensile bond strength of 3 resin cement systems; Superbond C&B, Panavia F 2.0 and Rely X Unicem with Adhesive Excite DSC on dentin soaked in 2.5% sodium hypochlorite solution for 3 minutes. By flattening human third molars to dentin surface depth and divided into 3 specimen groups. Bonded all 3 resin cements systems with resin composites by incremental filling. Consequently, specimen were stored in distilled water at 37 ℃ for 24 hrs. and sectioned into dumbbell shape to test for bond strength with a cross-head speed of 1 mm/min. The mode of failure specimens was categorized with stereomicroscope and captured their photos with scanning electron microscopy (SEM). The data were statistically analyzed with One-way ANOVA and Tukey Multiple Comparison (α = 0.05). The result shows that mean bond strength of Rely X Unicem with Adhesive Excite DSC and Superbond C&B were equal with no statistical difference and statistically higher than did Panavia F 2.0 system.
