Abstract
The invention relates to a dental composition comprising a hardenable powder to be used in a process for retraction of dental tissue. The invention also relates to a kit of parts comprising the dental composition comprising a hardenable powder, a hardening agent, optionally a handpiece of a powder jet device, optionally a powder jet device, and optionally retraction caps. In a further aspect, the invention relates to a method for retracting dental tissue comprising the steps of applying a dental composition comprising a hardenable powder with a powder jet device into the sulcus between soft and hard dental tissue, applying a composition comprising a hardening agent either before or after the previous step, leaving the dental composition in the sulcus for a time sufficient to effect retraction of the soft dental tissue and removing the dental composition from the sulcus.
