Comparison of Effectiveness of Moringa Oleifera Leaves Extract Gel (2%) with Retino A (0.1%) Cream for Treatment of Oral Leukoplakia: Double Blinded Randomized Control Trial.

Aim: The study aims to evaluate and compare the efficacy of Moringa oleifera leaf extract gel (2%) & Retino A cream (0.1%) in reducing the size of lesions in oral leukoplakia.

Objectives: The present study aimed to evaluate the efficacy of two interventions, Moringa oleifera mucoadhesive gel and Retino-A cream, in reducing the size of lesions in patients with oral leukoplakia. Specifically, the objectives were: (1) to assess the efficacy of Moringa oleifera mucoadhesive gel in determining the reduction in lesion size, (2) to assess the efficacy of Retino-A cream in determining the reduction in lesion size, and (3) to compare the efficacy of Moringa oleifera mucoadhesive gel (2%) in determining the change in lesion size in oral leukoplakia patients.

Methods: Clinically diagnosed cases of oral Leukoplakia were included in this study. The sample size is 72. Thirty-six patients had lesion sizes ranging from 2- 4 cm, and 36 patients had lesion sizes ranging from 4.1 - 6 cm that were equally distributed in the case and control groups using the chit system. The case and control groups had 36 patients with an equal size range of lesions. The case and control group participants will be advised topical application of the intervention and Retino-A thrice daily using a sterile cotton bud.

Results: M. oleifera gel (2%) was found to be more effective in the reduction in the size of the lesion as compared to Retino-A in the treatment of oral leukoplakia patients.

Conclusion: This study showed that M. oleifera mucoadhesive gel (2%) is an effective and safe treatment option for oral leukoplakia patients. It demonstrated a significant reduction in lesion size compared to Retino-A cream (0.1%) after 3 months of therapy, without any reported adverse effects. However, long-term follow-up studies are needed to evaluate its long-term effectiveness. The potent antioxidant property of M. oleifera makes it a promising candidate for further studies with concentration variations and in other potentially malignant oral disorders, such as lichen planus and OSMF. The development of chemotherapeutic drugs from M. oleifera for cancer treatment should also be considered. Overall, M. oleifera appears to be a promising natural alternative to synthetic drugs for the treatment of oral leukoplakia.
