基于16s rDNA 測序的全冠修復前后齦上微生物群落分析
首發時間:2022-03-15
摘要:目的:應用16S 核糖DNA(Ribosomal DNA,rDNA)三代測序技術探究全冠修復前后患者齦上菌斑生物膜的微生物群落分布結構以及多樣性。方法:收集烤瓷冠、全瓷冠修復患者的齦上菌斑樣本,以缺牙但未行修復患者同名對??牙的齦上菌斑作為對照組,應用16S rRNA高通量測序技術對樣本進行DNA測序,使用Qiime、R、PICRUSt2軟件對測序數據進行生物信息學分析。結果:共獲得110,209條有效序列,歸屬于1個界、11個門、23個綱、44個目、74個科、120個屬、188個種。在門和屬水平上,三組共有的物種是Actinobacteria,Bacteroidetes,Firmicutes,Fusobacteria,Proteobacteria和Rothia, Porphyromonas,Prevotella,Streptococcus,Veillonella,Leptotrichia,Neisseria,Citrobacter和Pseudomonas,三組之間的微生物多樣性在統計學上沒有顯著差異。物種差異分析表明,相較于對照組,全冠修復患者Haemophilus菌屬顯著增加。功能分析結果表明,與對照組相比,全冠修復后的細胞運動增加,而復制和修復、翻譯功能降低。結論:全冠修復改變最初微生物群落的組成,但是這種改變不足以引起口腔微生物群落和菌群功能的顯著變化。

Analysis of supragingival microbial community before and after full crown restoration based on 16S rDNA sequencing
Abstract:Using 16S ribosome DNA (Ribosomal DNA, rDNA) third-generation sequencing technology to explore the microbial community distribution structure and diversity of supragingival plaque biofilms in patients before and after full crown repair. Materials and Methods Collecting the supragingival plaque samples of patients with porcelain crowns and all-ceramic crowns. The supragingival plaque of the same-name antagonistic teeth of patients with missing teeth but not repaired was used as the control group. Using 16S rRNA high throughput sequencing technology to conduct DNA sequencing for the sample, using Qiime software, R software, and PICRUSt2 software to perform bioinformatics analysis on sequencing data. Results 110,209 valid sequences were obtained in the experiment, corresponding to 1 kingdom, 11 phyla, 23 classes, 44 orders, 74 families, 120 genera and 188 species. The predominant species shared by three groups were phylum Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, and genus Rothia, Porphyromonas, Prevotella, Streptococcus, Veillonella, Leptotrichia, Neisseria, Citrobacter, Pseudomonas. There were no statistically significant differences in microbial diversity among the three groups. And Species difference analysis showed that genus Hameophilus increased significantly after wearing dental prosthesis. Compared with the non-prostheses, functional analysis showed that cell motility had increased in the full crown prostheses, while replication and repair, translation had decreased.Conclusion Full crown restoration altered the initial microbial community composition, but this alteration was not sufficient to cause significant changes in oral microbial communities and microbiota function.
