Zuckerkandl's tubercle (teeth)

Zuckerkandl's Tubercle is a dental anatomical feature that is often observed in the development of the human molar teeth. Named after the Austrian anatomist Emil Zuckerkandl, this tubercle is a prominent bulge on the distal surface of the roots of permanent molars, particularly the third molar or wisdom tooth.

Anatomy[edit | edit source]

Zuckerkandl's Tubercle is located on the distal or back side of the root of the molar teeth. It is most commonly found on the roots of the third molars, also known as the wisdom teeth. The tubercle is a bulge or protrusion and is considered a normal variant of tooth anatomy. However, its presence can complicate dental procedures such as tooth extraction or root canal treatment.

Clinical Significance[edit | edit source]

The presence of Zuckerkandl's Tubercle can pose challenges in dental procedures. During a tooth extraction, the tubercle can increase the risk of root fracture due to its protruding structure. Similarly, during a root canal treatment, the tubercle can make it difficult to fully clean and fill the root canal system, potentially leading to treatment failure.

In addition, Zuckerkandl's Tubercle can also be associated with certain dental conditions. For example, it can be more prevalent in individuals with dental caries or tooth decay, as the tubercle can create areas that are difficult to clean and thus more prone to bacterial accumulation and decay.

History[edit | edit source]

Zuckerkandl's Tubercle is named after Emil Zuckerkandl, an Austrian anatomist who first described this feature. Zuckerkandl made significant contributions to the field of anatomy, particularly in the areas of dental and thyroid anatomy. His work on the tubercle has helped to improve our understanding of tooth development and morphology, and has had important implications for dental practice.
