Use of Er:YAG Laser for Disinfection of Infected Carious Dentin: Microbiological Evaluation and Scanning Electron Microscopy Analysis

Key Points

• The aim is to evaluate the antimicrobial efficacy of Er:YAG laser compared to aPDT for disinfecting infected carious dentin.
• Microbiological evaluation of treated carious dentin with Er:YAG laser at 50 mJ
• Comparison of antimicrobial efficacy with aPDT
• Scanning electron microscopy analysis of dentin surface post-treatment
• Er:YAG laser showed antimicrobial efficacy similar to aPDT
• Treatment time with Er:YAG laser was significantly shorter
• Indications support its use in minimally invasive dental procedures
