Hardness and Roughness of Nanofilled Maxillofacial Silicone After Two-Year Weathering

Mohammed Mousa's dataset contains Shore A hardness and surface roughness measurements for A-2000 maxillofacial silicone elastomer. The data covers 80 specimens with varying percentages of titanium dioxide and silica nanofillers, comparing weathered and non-weathered groups after two years. Analysis was performed using ANOVA and t-tests, with results last updated in April 2026.

Use Cases

• Predicting the effect of nanofiller concentration on material hardness based on Shore A durometer measurements.
• Analyzing the impact of long-term natural weathering on silicone elastomer surface roughness.
• Comparing the performance of silica versus titanium dioxide nanofillers as reinforcing agents in silicone matrices.
• Modeling chemical stability using FTIR spectroscopy results mentioned in the study description.

Strengths

• Dataset includes results from 80 accepted specimens, providing a basis for statistical analysis.
• Experimental design includes a controlled comparison of weathered and non-weathered groups over a two-year period.
• Specific hardness values are reported, such as 32.7 ± .34 Shore A for 10% SiO2.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 5.5 KB, indicating limited scope.
