Diversity analysis of the salivary fungal communities in the healthy subject (H), reticular OLP (R), and erosive OLP (E) groups. The fungal community of erosive OLP displayed significantly lower richness and α-diversity compared to the healthy controls for various diversity measures (P < 0.05). a Chao1 richness. b Shannon index. c Rarefaction curves of Chao1 richness obtained by combining samples in the same group. d Rarefaction curves of the Shannon index obtained by combining samples in the same group
