Treatmant of Oral Lichen Planus With Lycopene
the purpose of this study was to evaluate that if lycopene, a potent antioxidant can be used in the treatment of oral lichen planus. this could be useful as lycopene has no reported side effects and hence it can used in place of steroids which are commonly used for this condition and have many reported adverse effects.
lycopene can be used in the treatment of this condition as free radicals have been found to play a role in the cause of this disease and also lower levels of lycopene were seen in these patints.
Lichen planus, a chronic inflammatory mucocutaneous disease, occurs in about 2% of the adult population, affecting the skin and or oral mucosa. Clinically, lichen planus appears in keratotic, atrophic or erosive form. The atrophic and erosive forms are usually symptomatic.
Various treatment modalities viz. corticosteroids, antimicrobials, immunomodulators, phenytoin, retinoids, UV-radiation and surgical treatment etc. have been tried. Though none of these have shown to achieve satisfactory results with recurrence of lesion occurring in most of the cases after few weeks of discontinuation of therapy.
Recently a population based case control study has revealed lower levels of lycopene in atrophic and erosive oral lichen planus cases, while no significant difference was noted in any other carotenoid levels.
Lycopene is an antioxidant and free radical scavenger being used in the management of infertility, pre-eclampsia, cataract prevention, osteoarthritis, as adjuvant therapy in various malignancies, cardiovascular disorders, diabetes mellitus, aging, Alzheimer's disease, parkinsonism, etc.
Systemic lycopene has been found to be effective in treatment of oral leukoplakia, owing to its antioxidant properties.
The utility of lycopene in oral lichen planus has not been reported in the literature; therefore, this study has been designed to assess the efficacy of systemic lycopene in management of oral lichen planus patients.
The data collected from this study can move us closer to deriving a specific treatment plan for oral lichen planus - a dividend, not only for patients but dental fraternity as well.

Lichen Planus, Oral
Oral lesions accompanying cutaneous lichen planus or often occurring alone. The buccal mucosa, lips, gingivae, floor of the mouth, and palate are usually affected (in a descending order of frequency). Typically, oral lesions consist of radiating white or gray, velvety, threadlike lines, arranged in a reticular pattern, at the intersection of which there may be minute, white, elevated dots or streaks (Wickham's striae). (Jablonski, Illustrated Dictionary of Dentistry)
An oral retinoid used in the treatment of keratotic genodermatosis, lichen planus, and psoriasis. Beneficial effects have also been claimed in the prophylaxis of epithelial neoplasia. The compound may be teratogenic.
Conditions in which there is histological damage to the lower epidermis along with a grouped chronic inflammatory infiltrate in the papillary dermis disturbing the interface between the epidermis and dermis. LICHEN PLANUS is the prototype of all lichenoid eruptions. (From Rook et al., Textbook of Dermatology, 4th ed, p398)
The term applied to a group of relatively uncommon inflammatory, maculopapular, scaly eruptions of unknown etiology and resistant to conventional treatment. Eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. Proposed nomenclature divides parapsoriasis into two distinct subgroups, PITYRIASIS LICHENOIDES and parapsoriasis en plaques (small- and large-plaque parapsoriasis).
An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.
