Charles Stent Charles Stent Charles Stent (1807–1885) was a 19th-century English dentist notable for his advances in the field of denture making. In 1847, Edwin Truman introduced gutta-percha as a material for making dental impressions; however, this was unsatisfactory for several reasons, including its tendency to distort upon removal from the patient's mouth, and to shrink upon cooling.

He also added talc as an inert filler to give more body to the material, and red colouring. The
