We present an integrative review of the literature conducted to find and analyse specific measures for disinfection and/or sterilization of intraoral complex instruments, applicable to intraoral scanners. We performed a two-stage search in the PubMed/MEDLINE, SciELO, REDALYCS, and LILACS databases, and the Google Scholar website, which included full articles in Spanish, Portuguese, and English. The strategy associated the terms ‘disinfection’, ‘biosecurity’, ‘decontamination’, and (a) ‘intraoral scanners’, and (b) other ‘semi-critical’ intraoral complex instruments, according to the American Dental Association definition (e.g., ‘turbine’, etc). Strategy (a) produced just one outcome, whereas (b) produced nine articles, which only suggested low-level disinfectants.The lack of empirically based protocols that allow effective icrobiological control makes it necessary to create a new categorization for these instruments when trying to comply with American Dental Association recommendations for dental practice.

KEY WORDS: Disinfection; Sterilization; Decontamination; Safety; Equipment.
