Prevalência dos complexos microbiológicos amarelo, roxo e verde na lesão endodôntica-periodontal: uma revisão sistemática e metanálise

Abstract

Objective: To verify the prevalence of yellow, purple and green microbiological complexes in root canals (CRs) and periodontal pockets (BPs) of teeth diagnosed with endodontic-periodontal lesion. Materials and methods: This systematic literature review was conducted in accordance with PRISMA. Databases: Lilacs, Pubmed, Scopus, Web of Science, Embase, Open Gray, Proquest, Google, Cochrane, were searched from 8/2020 to 10/2020 by two independent reviewers, using MeSH terms and keywords , defined from the acronym PICOS (Population, Intervention, Comparison, Results, Studies). The selection of articles was performed using pre-established inclusion and exclusion criteria. The variables extracted from each article included: type of study, sample size, mean age, periodontal and endodontic clinical parameters, methodology and results of the prevalence of bacterial complexes in samples of CRs and BPs. Risk of bias and quality of evidence were assessed using the NIH Quality Assessment tool for Observational Cohort and Cross-Section Studies. In addition, a quantitative analysis using proportion meta-analysis was performed. Results: After applying the inclusion and exclusion criteria, 13 articles were initially selected by title and abstract. After the complete reading, 9 articles were excluded and 4 included for the present work. Streptococcus mitis (37.53%) and Veillonella parvula (50%) were the most prevalent species in BPs. Capnocytophaga sputigena (42.38%) and Veillonella parvula (70%) in the CRs. Conclusion: In teeth with endodontic-periodontal lesions, yellow and green bacterial complexes showed low prevalence. The only bacterial species found in both sites and with high prevalence was Veillonella parvula belonging to the purple complex.
