KSU Receives Patent for “Endodontic Point Containing Ultrasonic Deformable Material”

Dr. Mohammed Abdullah Alshehri, Restorative and Implant Dentistry Consultant at KSUMC, has registered a patent with the U.S. Patent and Trademark Office for the invention of "Endodontic Point Containing Ultrasonic Deformable Material."

Dr. Alshehri said that this invention is an innovative method of using endodontic point, a filler for root canal therapy, containing ultrasonic deformable material that decreases in viscosity when subjected to ultrasonic waves, sealing against the ingrowth of bacteria from the oral cavity. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped. He also confirmed that these materials are biocompatible.
