      abstract     = {The objective of this study was to investigate if
                      cryopreservation of teeth for long-term storage leads to
                      cracks in enamel and dentin.Three teeth, which were
                      extracted for orthodontic reasons, were cryopreserved in
                      liquid nitrogen (temperature -196°C) and thawed according
                      to standard protocols after 4 months. Micro computed
                      tomography using synchrotron radiation was performed to
                      detect cracks in the tooth hard tissues.Cracks were found in
                      the enamel of all teeth, which are associated with forceps
                      application during extraction. Cracks with a width larger
                      than 0.8 μm were not identified in dentin and
                      cementum.Although cryopreservation of teeth according to the
                      standard protocol does not generate cracks more than 0.8 μm
                      wide, the use of forceps can result in prominent cracks.},
