Research Abstract	The usefulness of low reactive-level laser therapy using a carbon dioxide laser for socket preservation in clinical cases has recently been reported. However, the mechanism of healing promoting effects of carbon dioxide laser irradiation remains unclear. Therefore, the emergence of osteoclasts and osteoblasts change and new bone formation of rats extraction sockets by carbon dioxide-enhanced healing process were investigated. Carbon dioxide laser irradiation has possibility to enhance the rapid bone resorption and new bone formation on the surface layer over the middle layer. It is suggested that carbon dioxide laser irradiation promotes the healing of tooth extraction sockets.
