Laser ablation (LA) therapy is a new approach to enhance microbial reduction in root canals after preparation. It uses laser energy absorbed by a solution to carbonize and kill microbes in the localized area through heat. Laser Assisted Irrigation also uses lasers to move traditional irrigants into hard to reach areas of the root canal, helping disinfect them. Photodynamic therapy similarly uses light activated chemicals to kill attached bacteria without harming surrounding tissues.
2. • Laser ablation (LA) therapy is a new approach to enhance microbial
reduction after the chemo-mechanical preparation of root canal .
• Laser ablation is a process where laser energy is absorbed by an
appropriate absorption solution resulting in heat thus carbonizing
tissue and killing the microbes in the localized area where the
solution is located
3. • Laser Assisted Irrigation moves traditional irrigants into hard-to-reach
areas .
4. • Photodynamic therapy (PDT) uses light to activate a chemical
attached to the bacteria killing them
• It does not affect unattached bacteria or surrounding tissues.
• Analogies would be heat sterilization for LA and cold sterilization for
PDT
