| Research Abstract |
1, Secondary dentin formation in dental pulp of rats was accelerated by continuous Nd : YAG laser irradiation, but it was notenhanced by He-Ne laser irradiationl.
2, Mineral formation in osteoblastic cell was accelerated by He-Ne laser irradiation.
3, He-Ne laser and Ga-Al-As laser had no influence on the concentration of Cytosolic calcium in osteoblastic cells.
