Mouse periodontitis models using whole Porphyromonas gingivalis bacteria induction

INTRODUCTION: Due to the increasing prevalence of periodontitis within the general population, it is important to study the progress and stages of periodontal disease and the efficacy of periodontal treatment through in vitro and in vivo experiments. Mouse periodontitis models are important in many in vivo studies. This study presents the findings from a scoping review of the current literature regarding the available method to produce mouse periodontitis models using whole Porphyromonas gingivalis (P. gingivalis) bacteria. METHODS: The scoping review was carried out based on the methodology described by Arskey and O’Malley. An electronic literature search was conducted in the PubMed database. Inclusion and exclusion criteria were established. The data were collected on a purpose-made data extraction table for descriptive analysis. RESULT: The researchers identified 11 articles that met the inclusion criteria for the review. Factors most considered in the literature relating to this topic are the vehicle to induce periodontitis, the type of strain for mice and P. gingivalis, the region of application, sacrifice day and the detection method used to measure the parameters. CONCLUSION: The most frequently used vehicle to induce a mouse periodontitis model is the combination of P. gingivalis with ligature. Future research on different types of vehicles and bacteria for inducing more effective and more time-efficient periodontitis models is needed to guide future researchers on this topic.
