Photodynamic therapy with photosensitizer photolon for oral leukoplakia
The objective – to assess tolerability, safety and immediate results of treatment of patients with oral leukoplakia using photodynamic therapy (PDT) with a photosensitizer photolon. The study included 40 patients (7 men, 33 women) with morphologically verified leukoplakia of the oral mucosa. The ave...

The study included 40 patients (7 men, 33 women) with morphologically verified leukoplakia of the oral mucosa. The average age – 55±14 years. Number of treated foci – 109 (1 to 8). Photolon was administered intravenously at doses of 1.7-2.5 mg/kg. Photoirradiation («UPL PDT», Belarus, λ = 660±5 nm) was performed 2.5-3 h after administration: light exposure dose varied from 25 to 100 J/cm2, power density of 0.07 to 0.32 W/cm2, the duration of one field photoirradiation – from 2 to 13.5 min and according to its linear dimensions.

Photodynamic therapy may be recommended for patients with circumscribed or widespread oral leukoplakia as a simple, well-tolerated and effective option.
