Effect of Light Intensity and Ceramic Barriers on Dual-Cured Cement Hardness

Forty samples of dual-cure resin cement were photoactivated under three ceramic types and a glass control using two LED light intensities. Vickers microhardness measurements were performed after 24 hours of dry storage, with results analyzed using factorial ANOVA and Tukey's test. The dataset was created by Gabriela Santos Fonseca and is available via paperswithcode under an Open Access license.

Use Cases

• Compare the microhardness of resin cement based on the ceramic barrier type mentioned in the description
• Analyze the effect of light source intensity (800mW/cm² vs. 1000mW/cm²) on cement polymerization
• Model the interaction between ceramic material and curing light intensity for optimal cement performance
• Validate experimental hardness results against a control group using a glass plate

Strengths

• Includes a control group with specific hardness values (e.g., 43.9±1.5 for 1000mW/cm²)
• Reports results for three distinct ceramic bases: Zirconia, Spinel MgAl2O4, and Lithium Disilicate
• Data was analyzed with statistical methods (factorial ANOVA and Tukey's test at 5% significance)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
