Title:
METAL FLUORIDE AND DENTAL COMPOSITION CONTAINING THE METAL FLUORIDE
Document Type and Number:
Japanese Patent JPH1036116
Kind Code:
A
Abstract:

To obtain a metal fluoride suitably used for dental materials to prevent dental caries through enforcing dental properties by forming a metal fluoride having a specific coated layer on the surface.

This invention refers to a metal fluoride having a polysiloxane coated layer on the surface. As the metal fluoride, above all, the fluoride of a metal of I and II groups in the periodic table, especially sodium fluoride is preferably used. As the polysiloxane, a polysiloxane obtained by condensing a silanol compound which is produced by (partially) hydrolyzing a silane compound expressed by the formula: [(R1O)l(X)m]4-n-Si-R2n [R1 is an organic group having ≤8C; X is a halogen; R2 is an organic group having ≤6C; (l) and (m) are each 0 or 1 (l+m=1); (n) is 0 or 1] is preferable. This metal fluoride is used as a dental composition capable of releasing fluoride ions by adding a polymerizable monomer and a polymerization initiator.
