Taking a precise impression is critical to the success and accuracy of the prosthetic restorations. The presence of swollen and inflamed gingival tissue compromises dryness of the prosthetic field and the accuracy of future impression. Laser photodynamic therapy is a new method for restoring the affected or inflamed gingival tissues after preparation in order to take a maximum precise impression.

Aim: The aim of this study is to demonstrate laser photodynamic therapy as a method of healing of gingival tissue prior to impression taking.

Methods and materials: In order to accelerate the healing of the gingival tissues, laser photodynamic therapy with a diode laser FOX (A.R.C. Lasers) and a photo activator EmunDo (Indocyanine Green) is applied twice. The procedure is performed in a therapeutic pulse mode with 200 mW, with a non-initiated fiber and exposure duration 30 seconds per tooth.

Results: Photodynamic laser therapy provides good healing, as well as a bio stimulating and regenerating effect. The dye affects only the damaged tissues and pathogens without harming the healthy ones.

Conclusion: Photodynamic therapy has a favorable healing effect on the gingival tissues. The advantage is the short exposure time, incessant control by the dentist, as well as the fast action.
