A Comparison of Traditional Chinese Medicine and Multiple Conventional Therapy in Treating Oral Lichen Planus: A...

To evaluate and compare the efficacy of seven conventional treatments and traditional Chinese medicine (TCM) combined therapies for oral lichen planus.

This study employs PubMed, Web of Science, Cochrane Library, and Cnki to collect studies. After evaluating the quality and bias risk, RevMan 5.4.1 and R Gemtc package was utilised with a visual analogue scale and side effects as outcomes, to compare the efficacy of the seven treatments.

This study included 20 studies, with a sample size of 1669. Our results suggest that photodynamic therapy and TCM demonstrate the most significant decrease in visual analogue scale and the rank is as follows: photodynamic therapy > TCM > TCM combined with non-hormonal immunosuppressive drugs > TCM combined with glucocorticoids > chloroquine combined with glucocorticoids > non-hormonal immunosuppressive drugs > glucocorticoids. Among them, compared to glucocorticoids, photodynamic therapy (-1.55, 95% CI: (-3.09, -0.02)), TCM (-1.25, 95% CI: (-2.46, -0.06)) significantly outperform in statistics. Moreover, no side effects were reported by the photodynamic therapy treatment. In the comparison with non-hormonal immunosuppressive drugs, the result indicates TCM (-4.17, 95% CI (-8.24, -0.34)), glucocorticoids (-2.78, 95% CI (-5.69, -0.17)) and their combination (-2.83, 95% CI (-5.93, -0.05)) have a significantly lower probability of the appearance of side effects.

This study indicates that TCM, from the perspectives of efficacy and the likelihood of side effects, outperforms all other common therapies, besides photodynamic therapy, in treating oral lichen planus.
