Glass Ionomer Cement Hardness with Carbon Nanotube Additives

Forty-eight specimens of glass ionomer cement were prepared to evaluate the effect of 2% carbon nanotube incorporation on surface microhardness. The dataset likely contains hardness measurements from five Knoop indentations per specimen across four material groups. The research was authored by Mayra Manoella Perez and is available via an Open Access license on Papers with Code.

Use Cases

• Compare material hardness based on cement type (conventional vs. high-viscosity) as described in the experimental groups.
• Analyze the effect of carbon nanotube inclusion on mechanical properties using the reported hardness values.
• Validate statistical findings (e.g., ANOVA, Tukey test results) mentioned in the study description.
• Benchmark new composite materials against the reported hardness values for Vidrion R and Vitro Molar cements.

Strengths

• Includes specific quantitative results: average hardness values with standard deviations for four experimental groups.
• Describes a controlled experimental design with 48 specimens divided into four groups of 12.
• Reports statistical analysis outcomes, including p-values for material type and CN inclusion factors.

Limitations

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