Preloaded dental cap and retraction material for gingival tissue retraction

A method and a device for effecting the cordless retraction of the gingival sulcus tissue that includes a cap or dam to be fitted onto a tooth. The well of the cap is pre-filled with a predetermined amount of a flowable non-setting kaolin based retraction material having a heavy viscosity or putty consistency. The preloaded cap is fitted to a prepared tooth so that when pressure is applied onto the cap, the retraction material is displaced under pressure and forced to flow into the sulcus, causing the gingival tissue to retract away from the tooth to enlarge the gingival sulcus. An internal ridge aids in retaining the retraction material within the cap.

DENTAL RETRACTION CORD FACILITATING ABSORPTION AND BLOOD CLOTTING

A retraction cord for use in a dental procedure for widening the gingival sulcus containing kaolin. The kaolin acts as a hemostatic agent and an absorber or hydrophilic agent to reduce bleeding and dry the gingival sulcus. A binder may be used to aid in retention of the kaolin on the fibers of the retraction cord. A lubricant or release agent may be used preventing blood clots from sticking to the retraction cord upon removal. Kaolin is affected and has no adverse side effects. 1.
