The College of Dentistry at King Saud University recently filed a request for a patent with the PCT (Patent Cooperation Treaty) branch of the U.S. Patent Office an invention called Dual Action Syringe.  The patent was applied in cooperation with the Intellectual Property and Technology Licensing (IPTL) Program in King Saud University.

The patent was obtained by Professors Mohiddin Dimashkieh and Dr. Mohammad Al-Obaida, faculty members at the College of Dentistry at King Saud University in Riyadh.

This invention was considerably modified from the traditional anesthetic syringe used in dentistry for more than 100 years. The two researchers were able to design a new anesthetic syringe that applies local anesthesia without seeing the needle and performing dental treatments conveniently and without pain.

The traditional mechanism of administrating local anesthesia in dentistry is sometimes so frightening that it prevented patients, young and old, from seeking treatment. Dimashkieh and Al-Obaida believe that the modified treatment will reduce individuals’ anxiety, therefore encouraging them to seek early treatment for dental injuries, tooth decay, gum disease, and other oral problems.

The modified system features a dual-action syringe with a carpule concavity surrounding the needle which dispenses an anesthetic gel before the injection is begun. Not only is the patients’ anxiety diminished because they see no needle before or after the injection, the application of anesthesia is faster and more accurate and the injection is minimally painful as the anesthesia seeps into the soft tissue during the needle’s insertion.

While the process was developed with the dental profession in mind, it can be used in many other medical procedures such as ophthalmology, dermatology, and preventive vaccinations. It is an extremely safe process in which the transmission of communicable diseases such as AIDS and hepatitis is avoided.
