| Research Abstract |
The strengthening effects of human dentin by UV irradiation were investigated with an aim of preventing tooth fracture. We found that a UV irradiation treatment with a wave length of 365 nm was significantly effective to improve the mechanical strengths of dentin with showing anisotolopy. The strengthening mechanism of dentin by UV was found to be the chemical changes in its type I collagen such as formation of new cross-links in relation with its typical amino acid such as proline.
