Synergistic Efficacy of Plaque Control with Intralesional Triamcinolone Acetonide Injection on Erosive Non-Gingival Oral Lichen Planus: A Randomized Controlled Clinical Trial.

This study is the first time to assess the synergistic efficacy and safety of plaque control on erosive non-gingival oral lichen planus (OLP). A randomized, controlled, clinical trial with blind evaluation was designed, and 48 OLP patients with erosive non-gingival OLP lesions were randomly assigned to the experimental group (n = 25, receiving intralesional triamcinolone acetonide injection, periodontal scaling, and oral hygiene instruction) and the control group (n = 23, only receiving intralesional triamcinolone acetonide injection) once a week for 2 weeks. Erosion size, pain level, plaque index, and community periodontal index were measured at every visit. Patients cured of erosion were followed up for 3 months to evaluate the recurrence rate. Adverse reactions were also recorded. At day 14 ± 2, the experimental group showed a higher completely healed percentage of erosion, a greater reduction of erosion size and pain level. However, no significant difference was observed in the recurrence rate. No participants had any severe adverse reactions. In conclusion, an improvement was observed in patients with plaque control, and future studies with larger sample sizes are needed to reinforce the external validity of this study.

Efficacy of intralesional betamethasone for erosive oral lichen planus and evaluation of recurrence: a randomized, controlled trial.

OBJECTIVE: This study aimed to determine the efficacy and safety of intralesional betamethasone in erosive oral lichen planus and to evaluate relapse of erosion. STUDY DESIGN: Patients were randomly assigned to the experimental group (1.4 mg intralesional betamethasone) or to the control group (8 mg intralesional triamcinolone acetonide), and they received injections once a week for 2 weeks. Erosive area and pain level were assessed on days 1, 7 ± 2, and 14 ± 2. If the lesion disappeared, any recurrence within the following 3 months was recorded. RESULTS: Twenty-nine participants in the experimental group and 30 in the control group completed the protocol. Healed percentage was higher with betamethasone (93.1%) than with triamcinolone (66.7%; P = .02), and final reduction in erosion area was greater in the experimental group (21.276 ± 21.064 mm(2)) than in the control group (11.5 ± 12.95 mm(2); P = .02). Reduction in pain level did not differ between groups. The proportion of participants with recurrent erosions was significantly lower in the experimental group (14.8%) than in the control group (45%; P = .04). CONCLUSIONS: Intralesional betamethasone may be used in the topical treatment of erosive oral lichen planus.

[Siblings present different clinical manifestations in white sponge nevus].

White sponge nevus (WSN) is a rare, autosomal-dominant hereditary disease. This article reported two siblings affected by white sponge nevus. Because of smoking or not, they presented different clinical manifestations.
