These are notes from an abstract to see the full abstract go here.Oral lichen planus (OLP) is a chronic inflammatory disease with different clinical presentations that can be classified as:
Although OLP is a relatively common disorder, the reports comprising large numbers of OLP patients with specific character are lacking in the literature.
Of the 674 patients, 65% were women and 34% were men. The most common clinical presentation was the reticular type, and symptomatic OLP was noted in 67% of the patients, mainly in those with the erosive form.
The erosive presentations showed significantly longer duration, more sites affected and a much greater older patients predominance than reticular or atrophic ones.
No statistically significant differences could be identified between OLP and diabetes, cardiovascular disease, smoking or alcohol use.
Precipitating factors that resulted in an exacerbation of the disease were frequently noted and included:
dental cusp (biting surfaces of the teeth)
poor oral hygiene.
The transformation of OLP into malignancy was observed in four patients at sites previously diagnosed by clinical examination as erosive or atrophic lichen planus.
A long time follow up is of utmost importance to detect its malignant transformation.
