Summary

Intentional replantation using Er:YAG laser and low-level laser therapy (LLLT) reduced post-operative pain and improved bone regeneration. This laser-assisted approach enhances disinfection and bioregeneration in complex endodontic cases.

Area of Science:

  • Endodontics
  • Laser Dentistry
  • Regenerative Medicine

Background:

  • Intentional replantation is a treatment option for complex endodontic cases.
  • Root resorption is a significant risk, often due to extraction trauma and infection.
  • Laser therapies offer bactericidal and biostimulation effects.

Purpose of the Study:

  • To evaluate the efficacy of Er:YAG laser and low-level laser therapy (LLLT) in intentional replantation.
  • To assess the impact of laser treatment on pain, healing, and bone regeneration.

Main Methods:

  • A molar with pulpitis and severe periodontal destruction was extracted using an Er:YAG laser for disinfection.
  • Low-level laser therapy (810 nm diode) was applied before extraction and immediately after treatment for biostimulation.

Main Results:

  • The patient experienced no post-operative pain.
  • Clinical follow-up revealed uneventful healing and significant bone regeneration.

Conclusions:

  • Er:YAG laser combined with LLLT aids disinfection in intentional replantation.
  • This combined laser therapy may preserve vital cells and enhance bioregeneration, leading to reduced pain and improved healing.
