Brief Summary

Lichen planus is a chronic inflammatory dermatosis. It most often affects the skin and mucous membranes. Sometimes lesions may appear in the area of nails (estimated at 10% of patients) or genital organs and anus. The most dangerous form of lichen planus is lichen that develops on the oral mucosa. It is believed to be the cause of the development of oral cancer. The vast majority of people suffering from lichen planus - 90%, experience spontaneous resolution of symptoms within a maximum of two years from the moment of their onset. In about half of the patients, the changes disappear within about 6 months. People who have a problem that their ailments do not want to go away on their own must take into account the fact that treating lichen is not the easiest one. Treatment of lichen is mainly based on alleviating its symptoms and accelerating the resolution of symptoms. Topical ointments containing strong glucocorticosteroids are usually applied to skin lesions or we can use Photodynamic Therapy

Outcome Measures

Primary Outcomes (1)

  • Size of Oral lichen planus

    the size of the oral lichen planus on oral mucosa in millimeters was assessed using a periodontal probe PCPUNC 15 we measured the height and length of the lesions

    12 weeks

Secondary Outcomes (1)

  • Pain rating

    12 weeks

Study Arms (2)

photodynamic therapy side

EXPERIMENTAL

On one side, the OLP lesion eligible for treatment was subjected to photodynamic therapy in four sessions every 2 days.Using as photosensitizer Methylen blue for 10min the lesion was irradiated with a 650 nm semiconductor laser at a dose of 120 J / cm2

Procedure: Photodynamic Therapy

Steroid side

ACTIVE COMPARATOR

on the other side The OLP on the other side was treated by daily sticking a cut-to-size carrier with 0.05% triamcinolone acetonide for 8 days

Drug: Triamcinolone Acetonide

Interventions

The OLP on the other side was treated by daily sticking a cut-to-size carrier with 0.05% triamcinolone acetonide for 8 days

Also known as: topical steroid administration
Steroid side

the olp was photosensitized with methylen blue and was irradiated with a semiconductor laser with a wavelength of 650 nm, using a dose of 120 J / cm2 and power density

Also known as: PDT
photodynamic therapy side
