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
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.
