Overview

In vitro study compares the impact of disinfectants on dentine morphology and microleakage, indicating Er:YAG laser is most effective.

Key Points

  • Er:YAG laser led to complete smear layer removal, promoting better dentine morphology, and reducing microleakage.
  • Analysis showed significantly higher mineral content in samples treated with Er:YAG laser compared to other methods.
  • Scanning Electron Microscopy revealed the differences in smear layer removal among the disinfecting treatments applied.
  • Control samples exhibited the highest microleakage, while those treated with Er:YAG laser showed the lowest leakage.
