Introduce a new anti-inflammatory and antioxidant paste preparation (curcumin paste) in the management of Oral lichen planus. – Assess the efficacy of this preparation on pain, clinical parameter and the level of IL-33 in saliva. – Compare the outcome of new preparation with the gold standard treatment (corticosteroids).
Full Title of Study: “The Effect of Topical Curcumin Versus Topical Corticosteroid on Pain, Clinical Parameters and Salivary Level of IL-33 in Oral Lichen Planus Patients: A Randomized Controlled Clinical Trial”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: Single (Outcomes Assessor)
- Study Primary Completion Date: May 1, 2020
Two groups will be prepared then decision of which one take curcumin paste will be selected according to randomized numbers in a sequentially numbered, opaque, sealed envelope 1 group will take topical corticosteroid and 1 will take curcumin paste then IL-33 level in saliva will be measured at the base line and at the end of 4th week pain and clinical parameters will be measured at 2nd and 4th week
- Drug: Triamcinolone
- Triamcenolone +napolycarboxylate
- Drug: Turmeric paste
- Topical turmeric paste (a mixture of curcumin powder and vegetable glycerin base in a ratio of 1:8 by weight) Mix with 85ml carbapol gel (125ml H2O + 0.5g carbapol + triethanolamine 3 drops) prepared in the Faculty of pharmacy-Cairo University
Arms, Groups and Cohorts
- Experimental: turmeric paste
- Topical curcumin gel (a mixture of curcumin powder and vegetable glycerin base in a ratio of 1:8 by weight) Mix with 85ml carbapol gel (125ml H2O + 0.5g carbapol + triethanolamine 3 drops) prepared in the Faculty of pharmacy-Cairo University traumeric extracted from Curcuma plant, it has anti-inflammatory, antioxidative and antineoplastic properties ((Nosratzehi et al., 2018), The curcumin is safe even in high doses, Since oxidative stress may play a role in pathophysiology of OLP, and by noting that OLP is a chronic inflammatory disease, the herbs which have both anti-inflammatory and antioxidant properties may efficiently control OLP (Kia et al., 2015).
- Active Comparator: Triamcenolone in orabase
- Triamcenolone + na ploycarboxylate
Clinical Trial Outcome Measures
- Pain intensity
- Time Frame: 4 weeks
- measured by Visual Analog Scale (VAS) 0 = no pain 10= severe pain 0= no pain 10= pain severe pain
- clinical sign score
- Time Frame: Baseline , 2nd week and 4th week
- measured by Thongprasom from score 0 to 5 0= only white lesion 5=area of erosion more than 2 cm
- IL-33 level in saliva
- Time Frame: base line and 4th week
- by ELISA
