Abstract

BACKGROUND: Oral potentially malignant disorders (OPMDs) not only harbour the risk of malignant transformation but can also affect patients' quality of life owing to severe symptoms. Therefore, there is an urgent need for therapeutic strategies to improve patients' quality of life. The objective of this meta-analysis was to comprehensively assess the efficacy of curcumin in the management of OPMDs. METHODS: PubMed, Embase, the Cochrane Library, and Web of Science were searched for clinical trials evaluating the efficacy of curcumin in the treatment of OPMDs from inception until March 2024. RevMan 5.4 software was used to perform statistical and subgroup analyses. RESULTS: Sixteen randomised controlled trials (1,089 patients) were selected. Curcumin exhibited comparable efficacy to conventional controls in alleviating pain (I2 = 98%, P = 0.49) and improving tongue protrusion (I2 = 94%, P = 0.51) in oral submucous fibrosis (OSF). Additionally, topical use of curcumin had an efficacy equivalent to that of conventional therapy in reducing pain (I2 = 83%, P = 0.31) and facilitating clinical remission (I2 = 67%, P = 0.38) of oral lichen planus (OLP). CONCLUSION: The topical use of curcumin may palliate pain and promote clinical healing in OLP patients. Systemic curcumin can ameliorate the degree of pain and tongue protrusion in OSF. Therefore, our study suggests that curcumin could serve as an alternative treatment for managing OPMDs with lower medical toxicity than steroids, especially when steroids are not suitable. Further studies with larger sample sizes and adequate follow-up periods are required to validate our results.

Key Findings

Sixteen randomised controlled trials (1,089 patients) were selected. Curcumin exhibited comparable efficacy to conventional controls in alleviating pain (I2 = 98%, P = 0.49) and improving tongue protrusion (I2 = 94%, P = 0.51) in oral submucous fibrosis (OSF). Additionally, topical use of curcumin had an efficacy equivalent to that of conventional therapy in reducing pain (I2 = 83%, P = 0.31) and facilitating clinical remission (I2 = 67%, P = 0.38) of oral lichen planus (OLP).
