My images in a Museum in Nuremberg

In October 2022, I was contacted by Dr. des. Susanne Thürigen, a historian of science from the Germanisches Nationalmuseum in Nuremberg, Germany. She expressed interest in using micro-CT images of certain teeth that I had developed to be displayed in the museum's permanent exhibition on crafts and medicine. Now, the images of the root canal anatomy system, which was co-developed by myself, Frank Paqué, and Holm Reuver, are permanently on display in the Spotlight-exhibition Danger Zone in Nuremberg. It's truly an exciting achievement!

Double Maxillary Molar Teeth

Conjoined teeth, a rare dental anomaly, have been described using various terms including gemination, fusion, double teeth, and twinning. Gemination refers to an attempted division of a single tooth germ, resulting in a tooth with a doubled crown and a single root. Fusion, on the other hand, occurs when two separate tooth germs fuse together, leading to a tooth with a larger crown and two distinct roots. In some cases, it can be challenging to distinguish between the two conditions, which is why some authors prefer to use the term "double teeth" for both. This condition usually affects anterior teeth, but it can also occur in premolars and permanent molars, albeit rarely. In 1963, Tannenbaum and Alling defined gemination as the formation of two teeth from a single follicle, with evidence of an attempt to keep them separate. Pindborg's definition of fusion involves the union of two or more separate developing teeth, which can result in either complete (total/true fusion) or incomplete (partial/late fusion) fusion, depending on the stage of tooth development. Overall, conjoined teeth can present diagnostic challenges, and proper identification and classification are important for appropriate management and treatment.
