| Abstract | ||
| Objectives: This in vitro study was performed to assess the effect of the silver diamine fluoride (SDF) solution in combination with the potassium iodide (KI) solution on the micro-tensile bond strength (µTBS) and shear bond strength (SBS) of glass ionomer cement (GIC) restoration bonded to the carious dentin of primary molars. Materials and Methods: 60 primary molars were collected and stored in saline. For the µTBS; 20 teeth were separated into two equal halves across caries and allocated randomly to intervention and control groups (n=20). For the SBS, 40 teeth were categorized into two groups, the intervention group (n=20) and the control group (n=20). The intervention teeth specimens were primed with 38% SDF followed by KI, and the control teeth specimens were primed with deionized water. The specimens were kept in saline for 14 days at room temperature before being restored with Fuji IX GP Extra. The specimens were prepared for µTBS and SBS testing after 24 hours in saline and the failure modes were analyzed. To compare the results of bond strengths the paired t-test was used. Results: The micro-tensile and shear bond strength results showed a statistically non-significant difference between the intervention and control groups (P>0.05). The mode of failure was the adhesive failure only in all groups. Conclusion: Pre-treatment of primary carious dentin with 38 percent SDF+KI (Riva Star, SDI, Australia) didn’t influence the micro-tensile or shear bond strength of glass ionomer restoration | ||
