Abstract: Described are new pasty masses that are suitable as insert material for widening the gingival sulcus. These retraction materials contain a paste-forming agent, superabsorber particles and at least one astringent. Surprisingly, it was shown that upon contact with fluid of such a retraction material paste formulation, for one, a volume expansion is occurs due to absorbed fluid and for another, a part of the superabsorber is diffused out of the paste and/or dissolved out and that this diffused and/or dissolved part in turn leads to the immediate thickening, bonding and/or coagulation of surrounding fluids such as saliva, blood and wound secretions. The effect is hemostasis, as well as widening of the sulcus.
