Abstract
AIM: The present study aimed to compare the effectiveness of intralesional placentrex versus hyaluronidase + dexamethasone injection in the symptomatic management of stage II OSMF. MATERIALS AND METHODS: This was a non-randomized prospective study conducted over a period of 14 months at a tertiary referral center. Patients with clinical stage II OSMF were randomly grouped into A(n = 18) and B(n = 17). These patients were treated with weekly intralesional injection of placentrex and hyaluronidase + dexamethasone respectively, over a period of six weeks. Variables such as mouth opening, burning sensation and colour of mucosa were evaluated at baseline(T0), second week(T1), fourth week(T3), sixth week(T4) of follow up. A p-value < 0.05 was considered statistically significant. RESULTS: A total of 15 patients completed the study in each group with regular follow up. The mean improvement in mouth opening was 4.3 ± 0.57 mms in group A(p-value < 0.001) and 7.2 ± 0.76 mms in group B(p-value < 0.001) which were significant at the end of six weeks. Mean change in burning sensation at the end of six weeks in group A was 1.2 ± 0.73(p-value < 0.001), and 3.6 ± 0.63(p-value < 0.001) in group B. Mean change in colour of mucosa at the end of six weeks was 1.4 in group A(p-value > 0.05) and 2 in group B(p-value > 0.05). On comparison between both groups, patients in group B exhibited better mouth opening and reduction of burning sensation than patients in group A(p-value < 0.001). CONCLUSION: Both intralesional placentrex and hyaluronidase + dexamethasone injection are effective in alleviating the symptoms of stage II OSMF. However, hyaluronidase + dexamethasone injection showed slightly better improvement in mouth opening and burning sensation after six weeks.
