Abstract
Aim: The present study aimed to evaluate the effect of silver diamine fluoride (SDF) and potassium
iodide (KI) on the micro-tensile and shear bond strength of resin-modified glass ionomer cement
(RMGIC) to dentin of primary molars.
Methods: Sixty freshly extracted primary molars were collected and stored in saline. For the microtensile bond strength, 20 teeth were sectioned into 2 halves through the carious lesions while for the
shear bond strength 40 teeth were assigned and divided randomly into 2 groups. group I was treated
with 38% SDF followed by (KI) while group II was treated with deionized water and then both
groups were restored with RMGIC. The specimens were placed in the universal testing machine to
apply tension and shear forces until bond failure.
Results: The mean and standard deviation of micro-tensile bond strength for group I and group II
were 8.75±0.96 and 8.43±1.04 respectively with no statistically significant difference with an
adhesive failure mode in both groups. While the mean and standard deviation of shear bond strength
for group I and group II were 1.38±0.22 and 1.26±0.41 with no statistically significant difference
with an adhesive failure mode in both groups.
Conclusions: Pretreatment of primary dentin with 38% SDF and (KI) did not affect the microtensile nor the shear bond strength of RMGIC.
