ABSTRACT

Seventy patients with oral lichen planus (OLP) were studied retrospectively. Several parameters were evaluated to compare between two groups of patients: those with non- erosive OLP and those with erosive OLP. Of the 70 OLP patients studied, 32 (46%) were males and 38 (54%) females. Ages ranged between 24 to 74 years, with a mean of 51 years.

The results of this comparative study can be summarized as following: 48 patients presented with non- erosive OLP and 22 cases with erosive OLP; no significant differences were found between the two groups in relation to age, sex, clinical type, site, duration of lesions, presence of other oral diseases, tobacco use, alcohol drinking or general medical diseases; the occurrence of anemia was significantly greater in the erosive OLP group than in non-erosive OLP group. The importance of these results are discussed and compared with the findings of others.
