Area of Science:

  • Dental Materials Science
  • Colorimetry
  • Spectrophotometry

Background:

  • Accurate tooth color matching is crucial in restorative dentistry.
  • Digital photocolorimetry, such as eLABor_aid (eLAB), offers objective tooth color assessment.
  • Comparability of eLAB with traditional spectrophotometry requires investigation.

Purpose of the Study:

  • To compare the reliability of eLABor_aid (eLAB) with spectrophotometry for assessing tooth color changes.
  • To evaluate the impact of intracanal medications on tooth color over time using both methods.

Main Methods:

  • Thirty bovine incisors were prepared and assigned to control, calcium hydroxide/propylene glycol, or triple-antibiotic paste groups.
  • Tooth color was measured using eLAB and spectrophotometry at baseline and at 1, 3, 7, and 14 days.
  • Statistical analysis included two-way repeated-measures ANOVA and Pearson's correlation.

Main Results:

  • No significant differences were found between eLAB and spectrophotometry for any group or time point.
  • Triple-antibiotic paste caused greater color variation compared to other groups.
  • Significant tooth color changes were observed in all groups after 7 days.
  • Strong correlations (R² 0.51–0.84) were found between eLAB and spectrophotometry.

Conclusions:

  • eLABor_aid (eLAB) is a reliable tool for detecting tooth color changes.
  • eLAB results are comparable to spectrophotometry, validating its use in clinical settings.
