Apatites, such as HAP, CAP, OAP are the materials excellent in biocompatibility, and are used for bone supplementation and substitution, root-canal-filling, and temporary sealing. This research examined the composition and characteristics of La-containing apatite (La-OAP). Bacteria are applied to an agar medium, in the center of which the filter containing apatite particles was placed. Light irradiation was performed from the upper and lower sides, and cultivation was carried out at 37℃ for 4-6 hours. With E. coli, the zones of inhibition were clearly observed, indicating that La-OAP may have antibacterial efficacy.
