Needless injection of dental anesthetics

许多牙科手术需要使用局部麻醉剂。每年有3亿支当地的 麻醉剂在世界范围内使用，局部麻醉剂的市场接近40亿美元。然而，在这方面， 许多病人，特别是儿童，有针头恐惧症。因此，在许多牙科干预中， 无法忍受针头，他们最终要么被束缚，要么在全身麻醉下接受治疗。这是一 患者的创伤经历以及医疗保健费用和从业者的负担。 牙科局部麻醉剂的无针注射将是牙科的一个重大飞跃，特别是在 儿科患者的管理。Idee International R & D Inc.开发了一种新 不使用针头注射药物的技术。在这个项目中，PI Tamimi博士在 麦吉尔大学将与Idee国际研发公司合作。优化牙科不必要的技术， 应用.为此，我们将首先研究射流如何通过不同的组织传播， 控制穿透深度。一旦获得这些信息，将很容易设置和优化喷气式飞机 用于特定牙科和颅面手术的设备。 该项目将使加拿大牙科患者受益，为他们提供更好，更便宜的服务。 治疗。它还通过加强一家加拿大生物技术公司对加拿大经济有利 并创造一种基于美国的技术，将降低牙科诊所的治疗成本， 全球局部麻醉剂市场

Many dental procedures require the use of local anaesthetics. Every year 300 million cartridges of local anaesthetics are used worldwide, and the market for local anaesthetics in nearing 4 billion dollars. However, many patients, especially children, have needle phobia. Accordingly, in many dental interventions, children do not tolerate the needles and they end up being either restrained or treated under general anesthesia. This is a traumatic experience for the patient as well as a burden to healthcare costs and practitioners. Needleless injection of local anesthetics in dentistry would be a major leap forward in dentistry, especially in the management of pediatric patients. The company Idee International R & D Inc. has developed a new technology to inject medications without the use of needle injections. In this project the PI Dr Tamimi at McGill University will work with Idee International R & D Inc. to optimize the needless technology for dental applications. To do so, we will first investigate how the jet propagates through different tissues in order to control the depth of penetration. Once this information is acquired it will be easy to set-up and optimize the jet device for specific dental and craniofacial procedures. This project would benefit Canadian patients with dental diseases by providing them better and less costly treatments. It also has benefits to the Canadian economy by strengthening a Canadian biotechnology company and creating a Canadian-based technology that will reduce the treatment cost in dental clinics and compete in the world market of local anesthetics.
