Die zunehmende Verbreitung der digitalen Volumentomografie (DVT) erweitert das Leistungsspektrum der bisherigen zweidimensionalen Zahnbildgebung mittels Röntgenaufnahmen oder Tomogrammen. Dem diagnostischen Mehrwert steht dabei eine erhöhte Strahlenbelastung der Patienten entgegen. Im Gegensatz dazu kommt die MRT ohne ionisierende Strahlen aus und bietet darüber hinaus einen deutlich höheren Weichteilkontrast. Der Nachweis morphologischer und numerischer Zahnveränderungen, die Differenzierung von periapikalen Läsionen und der Ausschluss von Komplikationen von Zahnerkrankungen sind dabei potenzielle Anwendungsgebiete der dentalen MRT. Vielversprechende Ansätze finden sich darüber hinaus beim Nachweis von Karies, der Parodontitis und der Schädigung des N. alveolaris inferior.

Growing distribution and utilization of digital volume tomography (DVT) extend the spectrum of clinical dental imaging. Additional diagnostic value, however, comes along with an increasing amount of radiation. In contrast, magnetic resonance imaging is a radiation free imaging technique. Furthermore, it offers a high soft tissue contrast. Morphological and numerical dental anomalies, differentiation of periapical lesions and exclusion of complications of dental diseases are field of applications for dental MRI. In addition, detection of caries and periodontal lesions and injury of inferior alveolar nerve are promising application areas in the future.
