Adolf Zsigmondy

Adolf Zsigmondy was a dentist of Hungarian origin who lived in Vienna. It was he who conceived the idea of charting teeth on the Zsigmondy-cross (called after him). This is the basis of the presently used marking method recommended by the FDI.

He was also the first to describe the contact and wear of the approximal side of the teeth. He continued to develop the cohesive gold fillings.cite journal | author = Huszár G | title = [The role of the life and works of Adolf Zsigmondy and Ottó Zsigmondy in the history of dentistry] [Article in Hungarian] | journal = Fogorv Sz | volume = 82 | issue = 12 | pages = 357–63 | year = 1989 | pmid = 2689240]

His son, Ottó Zsigmondy was also a dentist. His more limited professional field of research was the preserving dentistry. He used sodium-superoxide for widening the root canal and he made permanent fillings of black hard gutta percha. On the basis of observations carried out on himself he described the two-phase or temporal mastication called after him. He was also much engaged with professional politics, in his publications he strove for recognition of dentistry as an organic part of medical science.
