Dentin Tubule Occlusion Data with SEM and Permeability Measurements

548.8 MB of data from a study on dentin hypersensitivity treatment. The dataset, authored by Qiaojie Luo and last updated in April 2026, includes results from scanning electron microscopy, energy-dispersive X-ray spectroscopy, Vickers hardness tests, dentin permeability measurements, and confocal laser scanning microscopy tracer permeation experiments. Human dentin disks were treated with a novel Ca–Ag chemical regimen and commercial desensitizers to evaluate tubule occlusion depth and stability under mechanical and chemical challenges.

Use Cases

• Compare the efficacy of different desensitizing treatments based on dentin permeability reduction data
• Analyze precipitate morphology and occlusion depth based on scanning electron microscopy images
• Model the stability of tubule seals under simulated clinical challenges like abrasion and acid erosion
• Evaluate the suppression of pressure-driven fluid transport based on sodium fluorescein tracer permeation results

Strengths

• Dataset size is 548.8 MB, indicating substantial underlying data
• Includes multiple analytical methods: SEM-EDX, hardness testing, permeability measurement, and confocal microscopy
• Compares a novel chemical regimen (Ca–Ag) against three commercial desensitizers (Gluma, Duraphat, Actimins)
• Results include statistical significance indicators (p < 0.01) for key comparisons

Limitations

• Row count and specific column names are unknown, requiring inspection after download
• Column-level documentation is absent; field semantics must be inferred from the description
• Data is from a specific laboratory study; clinical validation is noted as future work
