Abstract: Objective To analyze the clinical and histopathological characteristics of oral lichen planus (OLP) complicated with type 2 diabetes mellitus (T2DM) through case-control study. Methods One hundred and four patients were divided into OLP group and OLP+T2DM group and their basic information, clinical types and REU scores of OLP were collected. Histopathological manifestations were described by two pathologists. Clinical and histopathological manifestations between the two groups were analyzed by SPSS 24.0. Results The prevalence of erosive OLP and REU score in OLP+T2DM group were significantly higher than those in OLP group (P<0.001). After one month follow-up, REU score of OLP patients taking hypoglycemic drugs decreased significantly (P<0.001), and that of OLP patients with ideal blood glucose control (P<0.01) decreased significantly. Logistic regression analysis showed that: high REU score, erosion type, dense lymphocyte infiltration, unclear lymphocyte infiltration zone, severe inflammation in the basal layer, and presence of fibrin in the basal layer (OR=1.58, 37.15, 8.49, 10.16, 3.94, 4.35) were typical characteristics of OLP with T2DM. Conclusion OLP patients with T2DM have more severe clinical lesions and higher degree of tissue destruction. A personalized plan should be made to obtain better treatment effect.
