Article Synopsis
  • Dental caries is a widespread yet preventable oral health issue, and biotics (including probiotics, prebiotics, symbiotics, and postbiotics) are suggested as affordable prevention strategies.
  • A review analyzed research from 2012 onward, revealing that while studies confirm probiotics can reduce harmful bacteria and increase pH levels in the mouth, more investigation is needed to fully understand how biotics work against cavities.
  • The combination of different types of biotics shows promise in caries prevention, but further studies are essential to refine their application and assess the effectiveness of postbiotics.

This review aimed to identify newly discovered bacteria from individuals with periodontal/peri-implant diseases and organize them into new clusters (GF-MoR complexes) to update Socransky's complexes (1998). For methodological development, the PCC (Population, Concept, Context) strategy was used for the focus question construction: "In patients with periodontal and/or peri-implant disease, what bacteria (microorganisms) were detected through laboratory assays?" The search strategy was applied to PubMed/MEDLINE, PubMed Central, and Embase. The search key terms, combined with Boolean markers, were (1) bacteria, (2) microbiome, (3) microorganisms, (4) biofilm, (5) niche, (6) native bacteria, (7) gingivitis), (8) periodontitis, (9) peri-implant mucositis, and (10) peri-implantitis.

Objectives: The aim of this study was to observe whether immediate implant placement (IIP) into damaged extraction sockets is a successful modality for treating hopeless teeth that require extraction.

Data Source: An electronic search was carried out through four databases (PubMed/MEDLINE, Web of Science, Scopus, and ScienceDirect) to identify randomized controlled trials (2013-2023) to understand whether IIP in damaged sockets is a successful treatment. The focus question was, 'In a patient with a hopeless tooth that needs extraction with the indication for dental implant treatment, is IIP in damaged extraction sockets, compared to undamaged sockets or healed sites, an effective method for the replacement of hopeless teeth and achieving a favorable clinical result?' The risk of bias was appraised and a meta-analysis using random effect was applied.
