Background: Bonding to the tooth structure and fluoride release of the restoration are substantial factors to prevent the caries progression in children. Objectives: The aim of this study was to compare micro tensile bond strength of four glass-containing materials with primary teeth dentin. Methods: In this in-vitro study, 16 extracted primary molar were prepared and disinfected with 0.2% thymol solution. The occlusal box was prepared until a thin enamel wall remained and the dentin exposed at the pulpal floor. This enamel wall played the matrix role for placing the restorative materials. The teeth were randomly divided into 4 groups and restored with resin modified glass ionomer (RMGI), giomer, zirconomer and cention N. The teeth were mounted in acrylic mold and entered into a CNC cutting machine to provide specimens with a thickness of 1 × 1 mm. The tensile bond strength of the specimens was calculated by micro tensile measuring device. The failure of the samples (adhesive, cohesive, admix) was observed under a stereomicroscope. The data were analyzed using one-way analysis of variance and Fisher's exact test. Results: There was a significant difference between zirconomer and other groups (P < 0.001), also between giomer and other groups (P < 0.001). There was no significant difference in the pattern of the failure among groups, except RMGI and cention N. Conclusions: The micro-tensile bond of the giomer was the strongest, cention N and RMGI were approximately of equal strength, and zirconomer showed the lowest tensile bond strength.

Objectives The purpose of this study is to compare the mechanical properties (compressive strength (CS) and diametral tensile strength (DTS)) of four different restorative materials: conventional glass ionomer (Fuji IX), ClearFil AP-X, Filtex Z350-XT, and Cention N. Materials and methods Specimens ( n = 80) were prepared from Fuji IX, ClearFil AP-X, Filtex Z350-XT, and Cention N for testing compressive strength and DTS. Statistical analysis Results obtained were subjected to one-way ANOVA and Tukey's post hoc test at significance ( p < 0.001). Results There were significant differences among restorative materials tested. ClearFil AP-X exhibits the highest mechanical properties (CS and DTS) and least values were obtained by the Fuji IX. Conclusion Strength is one of the most important criteria for the selection of a restorative material. Stronger materials better resist deformation and fracture, presenting more equitable stress distribution, greater probability, and greater stability of clinical success.

“…This is probably due to the toughening effect of ZrO 2 and the additive effect of HA. The homogeneous incorporation of nanoparticles in the glass component further reinforces the structural integrity of the GIC for high load tolerance and lasting durability [31][32][33].…”

The aim of this study was to investigate the effects of adding a nano zirconia-silica-hydroxyapatite (nanoZrO2-SiO2-HA) composite synthesized using a one-pot sol-gel technique to a conventional glass ionomer cement (GIC), which was then characterized using X-ray diffraction (XRD). Following the characterization studies, further investigations were carried out after the addition of nanoZrO2-SiO2-HA to cGIC (GIC nanoZrO2-SiO2-HA) at various percentages (~5% to 9%) to compare their fracture toughness, color stability, and sorption- solubility in relation to cGIC (Fuji IX). The XRD diffractogram indicated the presence of peaks for ZrO2, SiO2, and HA. The fracture toughness of GIC 5%nanoZrO2-SiO2-HA was statistically higher than that of other percentages of GIC nanoZrO2-SiO2-HA and cGIC. The highest values recorded were fracture toughness ( 1.35 ± 0.15 MPa . m 1 / 2 ), leading to an increase of ∼57%, as compared to cGIC. Overall, the color change ( Δ E ) values for GIC 5% nano Zr-Si-HA group were lower than those of cGIC over a one-month period and were between slight and perceptible. In addition, GIC 5%nanoZrO2-SiO2-HA recorded lower sorption values ( 23.64 ± 2.3 μ gm m − 3 ) as compared to cGIC ( 36.28 ± 2.6 μ gm m − 3 ) and higher solubility ( 66.46 ± 2.4 μ gm m − 3 ) as compared to cGIC ( 56.76 ± 1.6 μ gm m − 3 ). The addition of nanoZrO2-SiO2-HA to cGIC significantly enhanced its physicomechanical properties. Based on the results of our study, GIC nanoZrO2-SiO2-HA has the potential to be suggested as a restorative dental material with diverse applications ranging from cavity restoration, core build-up, and as a luting material.
