Laser assisted tooth replantation case report

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.
