This review aims to evaluate the safety of remimazolam for intravenous sedation during dental treatment and oral surgery. The protocol was registered in the Open Science Framework (registration DOI: 10.17605/OSF.IO/RFPSZ), and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). Literature searches and screenings were conducted using PubMed and the Cochrane database, with additional records manually reviewed from various sources. The selected studies, published in English, investigated the safety of remimazolam for sedation in dental and oral surgery. An initial search identified 20 studies, of which five prospective studies met the inclusion criteria. All included studies used an initial bolus administration of remimazolam. Primary outcomes assessed were the sedation success rate, incidence of adverse effects, onset time, awakening time, recovery time, and postoperative side effects. This scoping review indicates that all studies validated the superiority of remimazolam over other sedatives for dental treatment and oral surgery. The development and research of innovative technologies to reduce dental pain and anxiety presents opportunities for interdisciplinary collaboration and improved patient care in dental practice.Future clinical studies should focus on determining the optimal timing for additional dosing and discontinuation when remimazolam is administered continuously.

Many patients with underlying medical conditions are treated with local anesthetics in dental clinics. Dental local anesthetic cartridges contain the vasoconstrictor adrenaline, which can affect the cardiovascular system.For this reason, the adrenaline in the cartridge (2% lidocaine + 1:80,000 adrenaline) is sometimes diluted in order to avoid hemodynamic changes in these patients. However, at the same time, considerations have to be made for coring. Coring is a process in which a piece of rubber is scraped off when a needle is inserted into a rubber stopper, and the rubber is mixed with the drug solution. Particles generated during the coring process contaminate local anesthetic solutions. In this study, we closely observed the puncture site of a 33G dental needle inside a cartridge to investigate a safe dilution method that considers coring. The puncture site was located within 1.50 ± 0.08 mm (mean ± SD) of the diameter from the center of the rubber stopper of the cartridge head. Punctures were made with a 0.75-mm outer diameter metal needle outside the 1.50-mm diameter range from the center of the rubber stopper to reduce the overlap between puncture sites and minimize the risk of coring. After discarding half of the cartridge, 2% lidocaine without adrenaline was injected by piercing the end of the rubber stopper at the cartridge head with a 22–27G metal needle (outer diameter approximately 0.4–0.7 mm). This method minimizes the risk of rubber displacement and coring while ensuring a safe and effective dilution process. Providing a safer method for adrenaline dilution reduces the risk of coring and contamination in dental anesthetic cartridges.
