Career
lieutenant 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 foreign direct investment. 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.
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. Adolf Zsigmondy"s second son, Emil Zsigmondy, was a physician.
Both Ottó and Emil Zsigmondy were well-known mountaineers.
They took part in the first climb of the Meije by the east arête in July 1885, but Emil was killed on another attempted climb of the Meije the following month.
