PDT leads to clinical amelioration of OLP. (a) PDT induces a reduction of lesion size over time (D1-D56). (b) PDT leads to reduction of ABSIS score I over time (D1-D56). (c) Photographically documentation of lesion size reduction over time (D1-D56). (d) PDT leads to a reduction of ABSIS II score over time (D1-D56). (e) QoL parameters (burning, pain, food, oral hygiene) are improved after PDT treatment (D1-D56). *p < 0.05, **p < 0.01, ***p < 0.001. PDT, photodynamic treatment; QOL, quality of life.
