An in vitro assessment of glass ionomer cement shear bond-strength to demineralized dentin in primary teeth treated with silver diamine fluoride and potassium iodide

Comprehensive caries therapy has relied on eliminating contaminated tooth structure and replacing it with restorative materials in pediatric dentistry. SDF with GIC can be administered together to stop the caries in cavitated lesions. Therefore, it is of interest to assess the shear bond strength of glass ionomer cement (type IX) to demineralized dentin in primary teeth treated with SDF and KI. The occlusal edges of sixty non-carious primary molar teeth were sliced until the yellow dentin was discernible. Each sample was embedded in an acrylic block with its occlusal surface facing upward after being submerged in a demineralizing solution for 7 days. Three groups were created from the samples: Group 1: The untreated group (control group) to which GIC type IX was placed directly; Group 2: Samples received immediate application of GIC type IX after getting treated with silver diamine fluoride (Experimental group) and Group 3: Silver diamine fluoride followed by potassium iodide followed by GIC type IX application (Experimental group). A Universal Testing Machine was subsequently utilized to perform a shear bond test on the specimens. Data shows that previously treated cement with SDF+KI increases the shear bond test without negatively impacted the bond strength GIC to dentin.
