This comprehensive review explores the expanding applications of MRI in dentistry, highlighting its integration into routine diagnostic protocols and its significance in the evaluation of oral and maxillofacial structures. The article delves into the physics of MRI, detailing the various sequences such as Spin Echo (SE), Gradient Echo (GRE), and Short-Tau Inversion Recovery (STIR), each tailored for specific diagnostic needs. Advanced techniques like Dynamic Contrast-Enhanced MRI and Diffusion-Weighted Imaging (DWI) are discussed for their roles in assessing tissue perfusion and differentiating between benign and malignant lesions. The review emphasizes the necessity of appropriate coil selection and parameter optimization to enhance image quality, particularly in dental applications where artifacts from restorative and prosthetic materials can pose challenges. Furthermore, the article addresses the utility of MRI in visualizing dental hard tissues, the temporomandibular joint, and neurovascular structures, providing a comprehensive overview of its diagnostic capabilities. The integration of MRI into global health systems and the role of Personal Electronic Health Records in reducing redundant imaging are also examined. Conclusively, the review underscores the transformative impact of MRI on dentomaxillofacial diagnostics, advocating for its broader adoption in clinical practice to facilitate accurate diagnosis and effective treatment planning.</p>","PeriodicalId":41993,"journal":{"name":"European Oral Research","volume":"59 1","pages":"58-67"},"PeriodicalIF":0.9,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12126162/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
