Dental retraction composition, method of production and use thereof

A method for retracting soft dental tissue from hard dental tissue comprising:

• providing a dental retraction composition comprising:
• a liquid in an amount from 10 wt.-% to 35 wt.-% with respect to the whole composition;
• a layer type 1:1 silicate mineral in an amount from 1 wt. % to 30 to 30 wt.-% with respect to the whole composition and a layer type 2:1 silicate mineral in an amount from 35 wt.-% to 70 wt.-% with respect to the whole composition;
• an astringent in an amount from 0.01 wt.-% to 30 wt.-% with respect to the whole composition, and additive(s) in an amount from 0 wt.-% to 30 wt.-% with respect to the whole composition;
• wherein the dental retraction composition does not contain starch;
• wherein said dental retraction composition is contained in a container comprising a reservoir and a cannula;
• and
• applying said dental retraction composition to a sulcus between soft and hard dental tissue.

A process of dispensing a dental retraction composition, the process comprising:

• providing a dental retraction composition contained in a container comprising a reservoir and a cannula, wherein the dental composition comprising:
• a liquid in an amount from 10 wt.-% to 35 wt.-% with respect to the whole composition;
• a layer type 1:1 silicate mineral in an amount from 1 wt. % to 30 to 30 wt.-% with respect to the whole composition and a layer type 2:1 silicate mineral in an amount from 35 wt.-% to 70 wt.-% with respect to the whole composition;
• an astringent in an amount from 0.01 wt.-% to 30 wt.-% with respect to the whole composition, and additive(s) in an amount from 0 wt.-% to 30 wt.-% with respect to the whole composition;
• wherein the dental retraction composition does not contain starch:
• placing the container in an applier, and
• using the applier for dispensing the dental retraction composition out of the container.

A dental retraction composition comprising:

• a liquid in an amount from 10 wt.-% to 35 wt.-% with respect to the whole composition;
• a layer type 1:1 silicate mineral in an amount from 1 wt. % to 30 wt.-% with respect to the whole composition and a layer type 2:1 silicate mineral in an amount from 35 wt.-% to 70 wt.-% with respect to the whole composition;
• an astringent in an amount from 0.01 to 30 wt.-% with respect to the whole composition;
• and
• additive(s) in an amount from 0 to 30 wt-% with respect to the whole composition, wherein the storage modulus of the dental retraction composition is at least about 3000 kPa.
