Background and Objectives: In this study, methylene blue-mediated photodynamic therapy (MB-PDT) was used as a possible alternative method for the treatment of oral lichen planus (OLP). Study Design/Materials and Methods: Thirteen patients with 26 OLP lesions were enrolled in this study. Patients were instructed to gargle a 5% methylene blue solution in water for 5 minutes. Ten minutes later, irradiation was performed by laser light (l ¼ 632 nm, light exposure dose ¼ 120 J/cm 2 ). Lesions were evaluated pre and post-operatively and at follow-up sessions by changes in sign and symptom (pain) scores, and size of lesions. Results: Improvement in sign scores was achieved in 16 lesions. Four keratotic lesions disappeared completely. There was a statistically significant decrease in sign and symptom scores 1 week after treatment and at follow-up sessions up to 12 weeks. Average reduction in size of lesions was 44.3%. Conclusion: MB-PDT seems to be an effective alternative treatment for control of OLP. In our opinion, this preliminary result warrant further studies in order to show the efficacy of MB-PDT in control of OLP for a longer period of time.

An open, randomized, controlled study with two parallel treatment groups was done to evaluate the efficacy of a miconazole 2% gel compared with Zataria multiflora 0.1% gel applied four times daily for 2 weeks, in the treatment of Candida-associated denture stomatitis. Twenty four patients were included in the study. The efficacy variables were the colony count of Candida from the palatal mucosa and the denture surface and the erythema surface of the palatal mucosa on days 0, 7, 14, 21 and 28 after commencement of therapy. Twelve patients received miconazole gel and twelve Z. multiflora gel. The erythema surface was significantly reduced by both gels. No significant difference was seen between the two groups (p < 0.05). There was a significant reduction in the colony count of the palatal mucosa in both groups (except on days 21 and 28 in the Zataria group p = 0.07 and 0.08). Miconazole treatment reduced the number of denture colonies more efficiently than Z. multiflora except for day 21 when the efficacy of both groups was similar (p = 0.17). The results indicate that Z. multiflora gel reduced the surface erythema of the palate more efficiently than miconazole gel but did not reduce the colony count of the denture surface as efficiently as miconazole.
