Patent number: 11590061Abstract: A fluorine coating agent having enhanced dental tubule permeability and coating endurance, and a method for preparing the same. The fluorine coating agent applied on the surface of a tooth is enhanced in abrasion resistance to increase a period of time during which a coating membrane lasts, thereby preventing dental caries. Further, the curing time of the fluorine coating agent can be controlled to allow the agent to permeate and thus block the dental tubule.Type: GrantFiled: September 28, 2018Date of Patent: February 28, 2023Assignee: OSSTEMIMPLANT CO., LTD.Inventors: Il Seok Jang, Hanna Park, Su Kyoung Kim, Ju Dong Song, Tae Gwan Eom
