Abstract: Oral candidiasis is the most common oral fungal infection with complex clinical manifestations. At present, most physicians make diagnosis and treatment according to clinical impression only, but sometimes it is difficult to distinguish due to insufficient evidence. Therefore, it is necessary to combine with microbiological detection to further clarify the etiology and diagnosis. Direct chair-side microscopy, with the advantages of being fast, effective, non-invasive, and easy to repeat, is suitable for busy outpatient work, and can provide necessary etiological evidence for clinical diagnosis and treatment of oral candidiasis. This paper introduces the concept of microbiological diagnosis and integrate with long-term practical experience of oral candidiasis in clinic, and analyze and evaluate the application value of direct chair-side microscopy.

Key words: oral candidiasis, microbiological diagnosis, direct microscopy, chair-side assisted diagnostic technique, value analysis
