Abstract
Aim: To analyze subgingival fungal diversity in peri-implant inflammation patients and their relationship with bacteria. Methods: We collected saliva samples from four groups. 16sRNA and internal transcribed spacer sequencing was performed preceded by quantitative PCR and enzyme-linked immunosorbent assay tests. Analyses were done using R and Cytoscape software. Results: Significant differences were observed in the Abundance-based Coverage Estimator (ACE) index between control and peri-implantitis samples. Basidiomycota was the dominant fungal species, while Firmicutes dominated the bacteria. The most abundant fungal and bacterial species were ’s_unclassified g Apiotrichum’ and ’s_unclassified g Streptococcus’, respectively. Dothiorella was strongly associated with immunoglobulin G levels, with positive correlations between specific microorganisms and peri-implantitis in Q-PCR. Conclusion: Our findings have significant clinical implications, suggesting specific fungal and bacterial taxa roles in peri-implant inflammation.
