Anestesia dental local sin aguja: Una revisión integrativa de la literatura.

Abstract

Local anesthesia remains the backbone of pain control techniques in dentistry and is predominantly administered by injection using a syringe and needle. Nevertheless, needle-free local anesthesia techniques are also important adjuncts in the pain control armamentarium in dentistry, although they are not well known or widely used. The purpose of this review was to identify the available needle-free anesthetic techniques, to describe the devices used for administration, and to discuss future trends in the field. An English language integrative literature review was performed to assess publications over the last two decades using PubMed, Scopus, EBSCO, Science Direct, and Wiley Online Library databases based on the following keywords: local dental anesthesia, needleless anesthesia, pressure dental anesthesia, and intranasal anesthesia. Only articles and books of greater relevance were selected. Finally, 33 articles and one book were assessed. The currently available needleless dental anesthesia techniques rely on jet injectors, as well as intrasulcular and intranasal anesthesia, all of which employ different devices with their own inherent applications, advantages, disadvantages, and limitations that may be improved upon or overcome in the near future.
