Nonsurgical Periodontal Treatment by Erbium:Yag Laser Promotes Regression of Gingival Overgrowth in Patient Taking Cyclosporine A: A Case Report.

Objective and background: To report on a case of cyclosporine A-related gingival overgrowth (GO) treated by conventional scaling and Erbium:YAG laser that unexpectedly showed complete healing with normalization of the gingiva, making unnecessary further surgical treatment for gingival volume reduction. Since Erbium:YAG laser was approved in 1997 by the U.S. Food and Drug Administration for hard and soft tissue treatments in dentistry, several studies have been published to demonstrate its efficacy for bone cutting, plaque and subgingival calculus removal, and antiseptic effects both on soft and hard periodontal tissues.

Methods: We report herewith the case of a patient undergoing cyclosporine A therapy, affected by GO who underwent scaling and full mouth disinfection with chlorhexidine 2% rinses, followed by Erbium:YAG laser treatment of gingival pseudopockets, without surgical removal of the overgrown gingiva.

Results: Unexpectedly, complete healing of the periodontal tissues was observable after one single laser application and no adjunctive surgical procedure was necessary.

Conclusions: Erbium:YAG laser could be considered a really effective option for the nonsurgical treatment of drug-induced GO, avoiding the surgical procedures and also promoting a fast healing and a patient compliance surely higher than conventional techniques.
