Introduction: This review analyzes the increasing role
of magnetic resonance imaging (MRI) in dentistry and
its relevance in endodontics. Limits and new strategies
to develop MRI protocols for endodontic purposes are
reported and discussed. Methods: Eligible studies
were identified by searching the PubMed databases.
Only original articles on dental structures, anatomy,
and endodontics investigated by in vitro and
in vivo MRI were included in this review. Original articles
on MRI in dentistry not concerning anatomy and
endodontics were excluded. Results: All the consulted
studies showed well-defined images of pathological
conditions such as caries and microcracks. The enhanced
contrast of pulp provided a high-quality reproduction of
the tooth shape and root canal in vitro and in vivo.
Assessment of periapical lesions is possible even
without the use of contrast medium. Conclusions:
MRI is a nonionizing technique characterized by high tissue
contrast and high image resolution of soft tissues; it
could be considered a valid and safe diagnostic investigation
in endodontics because of its potential to identify
pulp tissues, define root canal shape, and locate periapical
lesions.
