Objective To investigate the short⁃term clinical effect of semiconductor laser exposure combined with
total glucosides of paeony (TGP) capsules for the treatment of erosive oral lichen planus (OLP). Methods Sixty⁃four
patients with erosive oral lichen planus were randomly divided into two groups: the experimental group and the control
group. Patients in the control group were treated with TGP capsules, while patients in the experimental group were treat⁃
ed with TGP capsules and semiconductor laser irradiation. The clinical effects were evaluated 3 months after treatment.
The data were analyzed using the SPSS 17.0 software package. Results Three months after treatment, the effective
rate in the experimental group was 90.6%, which was significantly higher than that in the control group (59.4%, χ2=
5.62, P < 0.05). The physical condition and visual analogue scale (VAS) scores in the experimental group were 2.17 ±
1.49 and 1.25 ± 1.29, respectively. The physical condition and VAS scores in the control group were 3.55 ± 1.41 and
2.09 ± 1.24, respectively. The physical condition and VAS scores in both groups were significantly higher after treat⁃
ment than before (P < 0.05). Three months after treatment, the physical condition score (t=3.805) and VAS score (t=
2.655) in the experimental group were significant higher than those in the control group (P < 0.05). Conclusion Semi⁃
conductor laser irradiation combined with TGP capsules can improve the short⁃term clinical efficacy in the treatment of
erosive OLP
