Overview

In vitro study compares microleakage in Class I cavities restored with five composite resins, suggesting material choice affects restoration success.

Key Points

  • This study aims to evaluate and compare the coronal microleakage of five different direct composite resins used in Class I cavity restorations.
  • Used 100 human premolars with Class I cavities for testing.
  • Restored samples with five different composite resins and bonding agents.
  • Performed thermocycling on all specimens before testing microleakage.
  • Submerged samples in Rhodamine-B dye and examined using a Confocal Laser Scanning Microscope.
  • Applied statistical analysis (ANOVA, Tukey, Student’s t-tests) to assess differences.
  • Tetric N-Ceram showed the least microleakage among the materials tested.
  • Filtek Z350 XT and Fusion Universal had moderate levels of microleakage.
  • Brilliant NG exhibited slightly higher microleakage levels.
  • Neo Spectra ST demonstrated the highest microleakage, significantly different from other materials.
