Applying the Gentle treatment (lows energies) of LiteTouch™ Er:YAG laser and 15% EDTA for just 60 seconds can completely remove the smear layer, open the dentinal tubules and remove endodontic biofilm of bacterial and fungal species like E. faecalis and C. albicans in the absence of undesirable thermal phenomena.
The LiteTouch™ Er:YAG laser energy can be applied at sub-ablative power levels (low energies) to potentiate an irrigant action (EDTA or NaOCL) into the root canal. The low energy of the LiteTouch™ laser (Gentle treatment) induce cavitation bubble expansion and collapse of the intra-canal irrigant followed by hydrodynamic pressure. This radial and longitudinal pressure is sufficient to move the irrigants into the dentinal tubules and lateral canals, obtaining the root canal debridement and disinfection.
The low energy utilized with LiteTouch™ Gentle treatment eliminates the risks of preheating, ablation and irrigant extrusion. The complex root canal system is more effectively cleaned and disinfected than with traditional endodontic techniques, improving the treatment prognosis.
The surgical endodontic treatment performed with LiteTouch™ Er:YAG laser has many advantages. The many advantages include: excellent visibility, high precision in tissue removal, enhanced infection control and elimination of bacteraemia, decreased or absent mechanical tissue trauma, fast tissue healing, reduced post-operative pain and edema as well as reduced scarring and tissue shrinkage.
The of ability of LiteTouch™ Er:YAG laser to reduce bacterial infiltration of the resected root after an apicectomy and retrograde obturation procedure, makes this laser the treatment of choice for endodontic surgery, especially for patients using antithrombotic medications.
