摘要：
Sulcus is retracted from teeth prior to perfroming a dental procedure on the teeth by applying an expandible curable silicone compound to the surface of the teeth and preventing the silicone compound from exanding in a direction away from the suface of the teeth, thereby forcing the silicone to expand against the sulcus and forcing retraction of the sulcus from contact with the teeth.
