Effect of low intensity laser supporting bone repair on a tooth with root perforation and periradicular lesion: case report and 12 years follow-up

José Cláudio Faria AMORIM, Oteir RAMOS-FILHO, Guilherme Augusto Alves de OLIVEIRA

Introduction: Low intensity laser has properties that may be effective in endodontic treatment, such as restorative capacity, antimicrobial performance and cell proliferation. Methods: This report describes the action of low intensity laser as an adjunct to bone repair of a root perforation and peri-radicular lesion in a tooth submitted to endodontic treatment, in which endodontic retreatment was performed only in the mesiobuccal canal using calcium hydroxide as intracanal medication and low level laser. The other canals were not submitted to retreatment, in spite of having peri-radicular lesions. Results: The low-intensity laser was effective as an adjunct to the bone repair process, restoring ad-integrum, interradicular bone and the peri-radicular lesions of the mesial and distal roots, after 12 years of follow-up. Conclusion: The laser at low intensity can be used as a coadjuvant to the treatment of perforations, demonstrating long-term success.
