All groups except Group 2 were contaminated with blood. Group 1 had no decontamination procedure, Group 3 was decontaminated by rinsing, Group 4 was decontaminated by 34% phosphoric acid etching, and Group 5 was decontaminated by 5% sodium hypochlorite application. RMGIC specimens were subsequently bonded with RC using a universal adhesive in self-etch mode. \u03bcSBS tests were conducted using a universal testing machine at a crosshead speed of 1 mm\/min. Failure mode analysis was conducted on RMGIC fracture surfaces under a scanning electron microscope.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Results:<\/jats:title>\n          <jats:p>\u03bcSBS results indicated that Group 4 had the highest mean \u03bcSBS value of 6.22 \u00b1 2.14 MPa, while Group 1 had the lowest mean \u03bcSBS value of 3.53 \u00b11.67 MPa. Significant differences were observed in the \u03bcSBS of Group 2 with no contamination (<jats:italic>p<\/jats:italic>=0.023) and Group 4 with decontamination by phosphoric acid-etching (<jats:italic>p<\/jats:italic>=0.003) when compared to Group 1 with blood contamination. No statistically significant differences (<jats:italic>p<\/jats:italic>&gt;0.05) were observed between all other groups\u2019 \u03bcSBS. For all groups, the predominant mode of failure was adhesive failure between the RMGIC-RC interface, with a few mixed failures in RMGIC for Groups 2-5.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Conclusions:<\/jats:title>\n          <jats:p>Blood contamination before adhesive application significantly reduced the \u03bcSBS between RMGIC and RC.
