Comparison of Triamcinolone Versus Platelet Rich Plasma Injection for Improving Trismus in Oral Submucous Fibrosis.
J Bahria Uni Med Dental Coll Jan ;10(1):58-62.

Objective: To compare the effect of Triamcinolone versus Platelet Rich Plasma (PRP) injection intraorally for improving trismus in Oral Submucous Fibrosis (OSMF). Study Design and setting: Randomized double-blind comparative study, conducted at ENT department of PNS Shifa Hospital, Karachi from 1st June 2015 to 30th June 2016. Methodology: Eighty patients with trismus due to oral submucous fibrosis were divided randomly into two groups, A and B of 40 patients each. In Group A, Inj. Triamcinolone 40mg (1 ml) was injected into the sub-mucosal plane in the retro-molar trigone area and into the fibrous bands along the soft palate on multiple sites, weekly for 6 weeks. In group B Inj. PRP 1ml weekly was administered for 6 weeks along the same site. Vernier calipers were used to precisely measure the Maximum Interincisal Distance (MIID) in cms before and after the treatment. Result: There was a male preponderance in the study group with a male to female ratio of 5.1:1. In group A mean pretreatment MIID was 2.3+-0.7 cms, while in group B, it was 2.2+- 0.5 cms. After completion of 6 weeks treatment the mean MIID improved in group A to 3.08 +- 0.8cms, and in group B to 3.22+- 0.5cms. The mean improvement in MIID in group A was 0.783+- 0.25cms compared to 1.01+- 0.05 cms in group B (p < 0.05). Conclusion: Intraoral injection of PRP is more effective than Triamcinolone in improving trismus due to OSMF.
