Study design, randomization, and blinding
OLP lesions
ATROPHIC
This study was a prospective, three-parallel arms, assessor-blinded, 12-week randomized clinical trial that included 30 patients diagnosed with erosive or atrophic OLP lesions. Eligible patients were randomized in a 1:1:1 ratio using computer-generated randomization assignment into three groups. The allocation concealment group sealed envelopes by a non-involved investigator. The outcome assessors were blinded to the type of intervention used.
