Question

Quizplus · Accepted Answer

A definitive diagnosis of oral lichen planus can only be established through a biopsy of the affected tissue. Clinical inspection is useful but not conclusive, and the presence of striae can also occur in other conditions. Cytological smear and development of periodontal pockets are not specific to oral lichen planus.
