title: Laser assisted tooth replantation case report.
abstract: OBJECTIVE
  Although intentional replantation for extraoral treatment is a solution for complicated endodontic cases, it is accompanied with risk of root resorption which is most likely due to extraction trauma and infected remnants. Laser therapies have long been proved for bactericidal and biostimulation effects. In the present case, a pulpitis combined severe periodontal destruction molar was extracted with an Er:YAG laser for thorough degranulation and disinfection. Before the extraction and right after the treatment, low level laser therapy (LLLT) with 810nm diode was applied for biostimulation.
  
  
  RESULTS
  Patient reported no post operative pain after laser treatment. Clinical follow-up showed uneventful healing, and excellent bone regeneration.
  
  
  CONCLUSIONS
  The Er:YAG laser coupled with low level laser therapy (810 nm diode) has shown to assist and improve intentional replantation in disinfection procedure, and it may preserve more vital cells and enhance bioregeneration for less operative pain and better healing.
