[Development and chinization of diagnostic criteria for oral lichen planus].

ABSTRACT

Oral lichen planus (OLP) is a common chronic inflammatory disease of oral mucosa. The diagnostic criteria of OLP is the cornerstone of clinical diagnosis and treatment and scientific research. However, there are various understandings of the diagnostic criteria in China. Thus several questions need to be answered, for example, how to combine the international diagnostic criteria with China's specific conditions, how to apply the criteria into clinical practice, and how to use the criteria guiding clinical work and scientific research in China. The authors of this article systematically introduced and discussed the development, content and difference of the international diagnostic criteria of OLP. We proposed "23 Princeples" for the selection of biopsy indications in OLP diagnosis based on authors' personal experiences in clinical and basic research and the actual conditions of Chinese clinicians. We also express our own views and suggestions about some other hot issues associated with OLP diagnosis.
