Document Type and Number:
WIPO Patent Application WO/2023/063076
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a tooth surface treating agent and a tooth surface treating kit, with which a uniform and high-strength layer formed of apatite is formed on a tooth surface to restore fine recesses in the tooth surface. This tooth surface treating agent contains: a liquid containing an organic acid and having a pH of 1.0-3.0; and hydroxyapatite particles having a particle diameter of at most 200 nm. Moreover, this tooth surface treating kit contains: a first treating agent which is a liquid containing an organic acid and having a pH of 1.0-3.0, and stored in a first container; and a second treating agent which is hydroxyapatite particles having a particle diameter of at most 200 nm, and stored in a second container different from the first container, wherein a tooth surface treating agent prepared by mixing the first treating agent and the second treating agent is applied onto a tooth surface to be treated.
