Clinical evaluation of a new laser enhanced ablation procedure (LEAP) in regenerative endodontics: a case report

Abstract

A new laser enhanced ablation procedure (LEAP) has been recently proposed in order to maximize the efficiency of intracanal disinfection and minimize the risk related to the extrusion of the irrigating solutions during endodontic therapy. The LEAP technique is based on the use of a diode laser which activates a laser absorption solution containing indocyanine green (ICG). In the present study, the use of LEAP was suggested as a final irrigation procedure which utilizes a safer and more biocompatible approach, avoiding the use of sodium hypochlorite and the risk related to its use in teeth with resorption. A 13-year-old boy was referred for endodontic treatment of a symptomatic lower left incisor. Dental history revealed a previous trauma. At the radiological examination, internal external resorption and large apical lesion were observed. Following the traditional chemomechanical approach, the LEAP protocol was used as an adjunct to improve disinfection before a regenerative procedure. After one-year radiographic healing had occurred and revealed normal periapical structures. The resorption process was stopped, and the patient reported being free of pain and able to use the tooth normally.
