Objective:To explore the effects of Triamcinolone acetonaide acetate inunction locally and cod liver oil a Liq inunction locally in clinical treatment of patients with oral lichen planus of non-erosion type.Methods:A total of 128 selected patients with oral lichen planus of non-erosion type in clinic were randomly divided into experimental group(n=66)and control group(n=62).Patients in experimental group underwent the treatment of Triamcinolone acetonaide acetate inunction locally;while patients in control group underwent the treatment of cod liver oil a Liq.inunction locally only.The pain index value at preliminary diagnosis and one week after treatment were evaluated

and the curative effect index value three weeks after treatment were compared between the two groups.Results:The evaluation of pain index reduced obviously(P<0.05)in experimental group one week after treatment.And there was statistical significance between the two groups(P<0.05).The index of comprehensive curative effect in experimental group was better than than in control group

which shewed statistical significance between the two groups(P<0.05).It shewed statistical significance when compared the evaluation of pain in experimental group on prior-treatment and post-treatment(P <0.001)

It also shewed statistical significance when compared the evaluation of pain in control group on prior-treatment and post-treatment(P<0.001).To compare the curative effect index value three weeks after treatment

there were dependablity between the change of alba-damage-area and the change of pain index value in experimental group(P <0.05).There were dependablity between the change of mucous hyperemia degree and the change of pain index value in experimental group(P<0.05).There were dependablity between the change of alba-damage-area and the change of pain index value in control group(P<0.05).There were no dependablity between the change of mucous hyperemia degree and the change of pain index value in control group(P>0.05).Conclusion:Triamcinolone acetonaide acetate inunction locally in clinical treatment of patients with oral lichen planus is more effective than cod liver oil a Liq inunction locally.
