| Research Abstract |
The strengthening effects of human dentin by heating were investigated with an aim of preventing tooth fracture. We found that a heat treatment with temperature at 110 to 140℃ was significantly effective to improve the mechanical strengths of dentin with showing anisotolopy. The strengthening mechanism of dentin by heating was found to be the compaction of dentin structure promoted by shrinking its collagen network.
