Efficacy of Curcumin in Oral Submucous Fibrosis

200 clinical stage 2 OSMF patients selected randomly by simple random technique with clinically & histopathologically confirmed diagnosis are divided into 4 groups with 50 patients each. In Group 1 patients are given 10% of curcumin mucoadhesive gel and are instructed to use it topically twice daily making it a daily dose of 1gm. In Group 2 patients are given 500mg of curcumin capsules and are instructed to take 2 capsules twice daily making a daily dose of 1gm. In Group 3 patients will be given 5% of curcumin mucoadhesive gel and will be instructed to use it topically twice daily & 250mg of curcumin capsules to be taken twice daily making it a daily dose of 1gm. Group 4 is considered as control group and provided with formulations without the active drug. The mean scores of 4 groups will be statistically tested using Anova technique. The differences in clinical parameters at 15 days, 1 month, 3 months & clinical & histopathological paramerters at 6 months will be compared between groups 1, 2, 3 & 4 by using students 't' test & correlation is also used for knowing the association of variables. For all tests, a 'p' value of 0.05 or less will be utilized for statistical significance. Other non parametric tests can also be applied where ever necessary for data analysis.
