Abstract
Introduction: Foraminal Enlargement (FE) is a cleaning performed in the apical-most region of the tooth, in order to optimize root disinfection. This systematic review evaluated the influence of FE during root canal treatment on bacterial reduction and repair of the periapical lesion.
Materials and methods: Searches in PubMed/MEDLINE, Scopus, Cochrane Library, Web of Science, Embase, Scielo, Lilacs and OpenGrey were performed until January-2024. Ex vivo and in vivo studies evaluating the effects of FE in the bacterial reduction and repair of the periapical lesion were included, respectively, followed by risk of bias assessment (modified version of Joanna Briggs Institute's for ex vivo studies and Systematic Review Centre for Laboratory animal Experimentation's risk of bias tools for in vivo studies). The meta-analysis was not feasible and a qualitative summary for each outcome was provided.
Results: Of 950 studies, 2 in vivo studies were eligible, using animal models with infected teeth. Of these two, periapical repair was evaluated with hematoxylin-eosin stain, and FE improved periapical healing. Regarding ex vivo studies, 3 were eligible, using extracted human teeth. The inoculations in ex vivo models were performed with Enterococcus(E.) faecalis, and FE reduced E. faecalis in the ex vivo models.
Conclusions: Foraminal enlargement seems to increase bacterial reduction within the root canal, and provide major periapical tissue repair on the histological analysis in animal studies. However, caution is necessary when translating these results to the clinical environment.
期刊介绍：
The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
