Needless injection of dental anesthetics

许多牙科手术需要使用局部麻醉剂。每年有3亿盒本地墨盒 麻醉剂在世界范围内被使用，当地麻醉剂的市场价值接近40亿美元。然而， 许多患者，特别是儿童，都有针头恐惧症。因此，在许多牙科干预中，儿童 不耐受针头，最终要么被限制，要么在全身麻醉下接受治疗。这是一个 这对患者来说是一种创伤体验，也是医疗费用和医生的负担。 在牙科中无针注射局麻药将是牙科的重大飞跃，特别是在 儿科病人的管理。艾迪国际研发公司开发了一种新的 无需使用针头注射即可注射药物的技术。在这个项目中，Pi Dr Tamimi at 麦吉尔大学将与艾迪国际研发公司合作，优化不必要的牙科技术 申请。要做到这一点，我们将首先研究喷射如何通过不同的组织传播，以便 控制穿透深度。一旦获得了这些信息，就可以很容易地设置和优化喷气机 用于特定牙科和颅面手术的设备。 该项目将使加拿大牙病患者受益，为他们提供更好的服务和更低的成本。 治疗。它还通过加强一家加拿大生物技术公司的实力，给加拿大经济带来了好处 并创造了一种基于加拿大的技术，将降低牙科诊所的治疗成本，并在 局麻药的世界市场。

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.
