Needle-free anesthesia system in dentistry: challenges and perspectives

Abstract

Fear of needles is a barrier to access to dental health, affecting millions of people around the world. Although local anesthesia is still a fundamental pillar in dentistry, the traditional syringe and needle technique can cause fear and anxiety in many patients. Modern dentistry has made significant strides in the development of new anesthetic techniques, and needle-free options are a testament to this progress. The aim of this research is to present an updated systematic literature review on needle-free anesthesia injection systems for the period 2020-2024. The PRISMA methodology was used for the selection of the articles to be analyzed. A focus group was developed to determine the knowledge of dental professionals and students regarding pressure systems. It was emphasized that the INJEX systems, Comfort-in and MadaJet XL, are less traumatic and generate less stress, which is important for patient acceptance. A training program was proposed for dental professionals and professors, in these techniques, for the research and development of new needle-free solutions, which is essential to make dental care more accessible and enjoyable for everyone.
