Dear Editor, Oral lichen planus (OLP) is a chronic inflammatory condition with a long clinical course and potentially negative impact on quality of life.1,2 The heterogeneous clinical presentation, lack of treatment consensus yet a need to ensure therapeutic efficacy, is compounded by the absence of a standardized and comprehensively validated disease scoring methodology. The ODSS is primarily a disease severity scoring system; the subjective element of ODSS does not replace validated patient-reported outcome measures, such as the Chronic Oral Mucosal Disease Questionnaire.11 Construct validity was not examined, and this may be an area for further investigation. The Oral Disease Severity Score (ODSS) is a detailed oral scoring system that has been validated for use in oral pemphigus vulgaris (PV) and mucous membrane pemphigoid (MMP).3,4 We have previously demonstrated its usefulness for oral lichen planus.5,6 The aim of this study was to formally validate the ODSS in OLP.
