The Prepometer device is reproducible for measuring dentin permeability via electrical resistance. However, it does not accurately correlate with remaining dentin thickness, limiting its clinical use for preventing pulp injury.

Area of Science:

  • Dental materials science
  • Biomaterials engineering
  • Restorative dentistry

Background:

  • The Prepometer device measures dentin electrical resistance to assess permeability.
  • Accurate assessment of remaining dentin thickness is crucial during tooth preparation to prevent pulp injury.

Purpose of the Study:

  • To evaluate the reproducibility and accuracy of the Prepometer device.
  • To determine the correlation between electrical resistance measurements and remaining dentin thickness.

Main Methods:

  • Standardized cavities were prepared in 12 intact teeth.
  • Prepometer measurements were taken in vivo before extraction.
  • Remaining dentin thickness was measured in vitro using microfocus-computerized tomography.
  • Correlation coefficients and intra/inter-investigator variability were calculated.

Main Results:

  • The Prepometer demonstrated good intra- and inter-investigator reproducibility.
  • No significant correlation was found between electrical resistance measurements and remaining dentin thickness.
  • The device showed a limited safety zone, with some false negatives and positives for remaining dentin thickness.

Conclusions:

  • The Prepometer is a reproducible device for assessing dentin permeability.
  • Electrical resistance measurements do not reliably indicate remaining dentin thickness.
  • Further randomized clinical trials are needed to validate the Prepometer's effectiveness in preventing pulp injury.
