Acid-neutralizing resins and hardenable dental compositions thereof

1. A dental composition comprising

a. 0.5-10% wt/wt of non-polymerizable acid-neutralizing resin (I) or 0.5-99% wt/wt of an acid-neutralizing polymerizable resin (II) or a mixture of (I) and (II), featuring a moiety that is capable to effectively neutralizing an acid group, where the neutralized acid group is as carboxylic acid, sulphonic acid, phosphonic acid or phosphoric acid,

b. 5-90% wt/wt of mixed conventional polymerizable resins;

c. 0.01-5.00% of Initiators and other additives;

d. 0-90% wt/wt a plurality of filler particles ranged from 10 nm-50 micron; wherein the non-polymerizable acid-neutralizing resin has a formula of (I) :

wherein the acid-neutralizing polymerizable resin has a formula (II) of:

R′: H or Me;

X is O, S, NH, NR1, where R1 is CH 3 or C 2 H 5 ,

Y is O, S, NH or NR or R;

R and Y are the same or different and have C 1 -C 24 , linear and/or branched alkylene residue, or aromatic/substituted residue;

M is an alpha-substituted tertiary amine, pyridine or substituted pyridine, imidazole and/or substituted imidazole, pyrrole and/or substituted pyrrole, piperidine and/or substituted piperidine, pyrazole and/or substituted pyrazole, oxazole and/or substituted oxazole, thiazole and/or substituted thiozole, isoxazole and/or substituted isoxazole, isothiazole and/or substituted isoxazole, thiadizole indole and/or substituted thiadizole indole, indolizine and/or substituted indolizine, triazole and/or substituted triazole, tetrazole and/or substituted tetrazole, pentazole and/or substituted pentazole, quinoline and/or substituted quinoline, isoquinoline and/or substituted isoquinoline isoquinoline, pyridazine and/or substituted pyridazine, pyrimidine and/or substituted, pyzazine and/or substituted pyzazine, cinnoline and/or substituted cinnoline, phthalzine pyrimidine and/or substituted phthalzine, quinazoline and/or substituted quinazoline, quinoxaline and/or substituted quinoxaline, phenazine and/or substituted triazines, triazines and/or substituted triazines or any combination of these, and n is from 1 to 10 and m is from 1 to 10.

2. The dental composition of claim 1 , wherein M is

3. The dental composition of claim 1 , wherein the formulated composition is capable of eliminating the need of a self-cure activator in a dental adhesive.

4. The dental composition of claim 1 , wherein the formulated composition has antibacterial capability.

5. The dental composition of claim 4 , wherein the formulated composition optionally includes a cationic complex with a weak acid, from which an acid exchange occurs during contact between a cured adhesive containing a strong acidic component and a dual-cure restorative containing the cationic complex.
