A one-part self-etching, self-priming dental adhesive having a pH of at most 2, which comprises an aqueous mixture containing 

Dental adhesive

Non-aqueous dental adhesive comprising a mixture containing (i) one or more polymerizable monomers optionally containing an acidic group, (ii) a polymerization initiator, and (iii) a thermal polymerization inhibitor of the following formula (I) whereinR'represents a hydrogen atom, or a saturated hydrocarbon group having 1 to 18 carbon atoms. R&#x2032;, which may be the same or different if more than one R&#x2032;is present, independently represent a saturated hydrocarbon group having 1 to 18 carbon atoms, and c represents an integer of from 1 to 4, and (iv) optionally an organic solvent.

Self-adhesive dental restorative composition comprising (i) 10 to 40 percent by weight based on the total weight of the composition of a mixture of hydrolysis-stable polymerizable monomers of the following formula (I): wherein R is a m+n valent organic group having 1 to 20 carbon atoms and optionally 1 to 5 atoms selected from the group of nitrogen, oxygen and sulfur atoms; A independently represents a moiety of the following formula (II): wherein L is a hydrogen atom, a C1-6 alkyl group, a C3-8 cycloalkyl group, a C6-14 aryl group or a group of the following formula (III) wherein R' is a hydrogen atom, a C1-6 alkyl group, a C3-8 cycloalkyl group, or a C6-14 aryl group; X is O, S, NH or NR&#x2033; wherein R&#x2033; is a C1-6 alkyl group, a C3-8 cycloalkyl group, a C6-14 aryl group; a is 0 or 1; M is a group of the following formula (IV) wherein Y is O, S, NH or NR&#x2032;&#x2033; wherein R&#x2032;&#x2033; is a C1-6 alkyl group, a C3-8 cycloalkyl group, a C6-14 aryl group; b is an integer of from O to 3; c is O or 1; d is an integer of from O to 3; provided that when b is O, then Y cannot be O; x is 0 or 1; y is 0 or 1; provided that x and y cannot be both 1, and provided that x cannot be 1 when L or a group of formula (III) is a hydrogen atom, and provided that when x is 0 then a is also 0, and provided that when y is 0 then b is greater than 0 or c is 0; B independently represents an acidic group; m is an integer of from 1 to 5; n is an integer of 0 to 3; and m+n is at least 2; (ii) 60 to 90 percent by weight based on the total weight of the composition of a filler; and (iii) an initiator system; wherein the portion of monomers of formula (I) wherein n is greater than 0 is at least 1 percent by weight based on the total weight of the mixture.

Total etch dental adhesive composition

One-part self-etching, self-priming dental adhesive composition having a pH of at most 2, which comprises (a) a polymerizable acidic phosphoric acid ester monomer (b) one or more polymerizable acidic monomers (c) a polymerizable N-substituted alkylacrylic or acrylic acid amide monomer; (d) optionally an organic and/or inorganic acid; (e) an organic water soluble solvent and/or water; and (f) polymerization initiator, inhibitor and stabilizer.

One-part self-etching, self-priming dental adhesive composition

A composition including nanoparticles each having an acidic polymerizable siloxane moiety. For example, a hydrolysis stable, self-etching, self-priming dental adhesive composition including 90 to 10 percent by weight of an aqueous phase, and 10 to 90 percent by weight of acidic polymerizable nanoparticles. The acidic polymerizable nanoparticles are obtainable by hydrolysis of a mixture containing one or more hydrolyzable organosilicon compounds wherein (i) at least a portion of the hydrolyzable organosilicon compounds contains one or more polymerizable groups and (ii) at least a portion of the hydrolyzable organosilicon compounds contain one or more acidic moieties.
