What Causes Lichen Planus?

Exposure To Certain Chemicals

Exposure to certain chemicals is a strong risk factor for lichen planus. Gold, arsenic, iodide compounds, and certain dyes used for medical procedures are some of the many chemical sources linked to this condition, and it occasionally develops as a reaction to metals in dental fillings. Individuals who work with gold, arsenic, or other potentially hazardous chemicals should speak with their employer about the appropriate safety precautions for handling these, and they should wear all required protective gear when working. Anyone who is going to have a medical procedure involving the use of contrast dye should check with their healthcare provider about the risks associated with the dye and whether there may be an alternative contrast available. At the dentist, patients who are told they need a filling or other dental work should ask about options that do not use mercury or metals. Individuals exposed to chemicals should remain vigilant for possible symptoms of lichen planus and report these to their healthcare provider as soon as they are observed.
