Special type of laser pointer for controlled destruction of bones
In periodontal surgery, a type called Er is used. YAG's special type of laser can control the destruction of bones. The bone will heal faster than the bone that uses conventional drilling. Therefore, the researchers are very interested in Er. Whether YAG laser pointer irradiation changes the expression of SOST in bones is of interest. Yujin Ohsugi, the first author of the paper, said. We began to compare the gene expression and biological healing response of laser-cauterized, drilled and untreated bones. And to study the biostimulation effect of Er: YAG laser on osteogenic cells.

Through microarray analysis, the researchers studied the rat skull for the first time 6 hours after drilling and laser treatment. Gene expression patterns during the healing process at 24 and 72 hours. Sayaka Katagiri, the author of the paper, said: “Studies have shown that the expression of sclerostin in bones irradiated by lasers is reduced in vivo or in vitro. Sequence microarray analysis shows that within 24 hours, the bones that have been drilled and processed Bone. There is a clear difference in the gene expression patterns of the two. The former may induce a large amount of potential inflammation. It is worth noting that after 6 hours of laser treatment. Pathways related to inflammation are not affected. This indicates that laser irradiation can Effectively stimulate organisms."
