Establishment of an <scp>MRI</scp> ‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

This study suggests the potential of MRI as a novel non-invasive and quantitative diagnostic method for critical pulpal inflammation zones. Moreover, MMP9 was identified as a reliable biomarker of critical pulpal inflammation. Future studies will focus on validating the potential biomarker role of MMP9 and analysing low MR signal areas for other novel biomarkers of critical pulpal inflammation.
