Résumé de communication

Objectives: Several clinical studies of the photodynamic treatment of actinic keratosis and actinic cheilitis demonstrated that White LED photodynamic therapy(PDT) is a valuable alternative to conventional PDT performed with red light with better tolerability (almost painless) and lack of inferior efficacy. In addition, White LED illumination seems to present practical advantages in comparison with outdoor daylight PDT because the spectrum and light dose are fixed and reproducible and it is always feasible and programmable regardless of weather and environmental problems.
