Objective: The aim of this study was to investigate the effectiveness of triamcinolone acetonide (TA) and salvianolic acid B (SA-B) intralesional combined injection in the treatment of oral submucous fibrosis (OSF).
Material and methods: A randomized clinical trial was performed. TA, SA-B, and TA combined with SA-B were consecutively applied intralesionally weekly for 20 weeks. Mouth opening and burning sensation improvement as determined by a 100-mm visual analog scale were evaluated at weeks 10, 20, and 44.
Results: Forty-two subjects fulfilled the study without obvious adverse reactions. The net gain in mouth opening was 2.00 ± 1.21 mm in the TA group, 3.48 ± 2.23 mm in the SA-B group, and 5.50 ± 1.80 mm in the TA + SA-B group at week 44. The burning sensation improved by 3.05 ± 0.76 in the TA group, 4.96 ± 0.97 in the SA-B group, and 6.11 ± 0.93 in the TA + SA-B group by the end of the study.
Conclusions: TA + SA-B intralesional injections improved mouth open and burning sensation in these OSF patients.
