“…In this study, the effect of surface disinfection of handpieces was similar to the results reported by Pinto et al [ 12 ] in a study in human dentistry, where handpieces did not meet even the less strict criteria for high-level disinfected equipment in human dentistry [ 9 ]. The couplings in both LSH and HSH can be regarded as a bridge between external and internal surfaces.…”

“…Several studies on human dental equipment demonstrate the challenges to meet criteria for both high-level disinfected and sterile equipment for handpieces. Surface disinfection of the external surface of handpieces resulted in failure to meet the criteria for high-level disinfection [ 12 ]. In another study, one of four cleaning devices intended for handpieces, the washer-disinfector (WD), provided an acceptable test result [ 13 ].…”

Equine dentistry has developed immensely and human dental equipment, such as handpieces, are often used. Measures to avoid the spread of infectious microorganisms are important, but this is challenging since handpieces are difficult to decontaminate. Thus, it is necessary to develop effective IPC measures in equine dentistry. The aim of this study was to contribute to the evidence needed for future evidence-based guidelines on IPC by investigating hygiene in equine dentistry. Used handpieces and dummies (i.e., handpieces not used during dental procedure, reflecting environmental bacterial contamination) and the head support were sampled each day before the first patient, for each patient after treatment, and after decontamination. All equipment was sampled with 3M TM Swab Samplers and the head support additionally sampled with dip slides. After dental procedures, the detected bacterial load was often high on used handpieces, dummies, and the head support. After decontamination, handpieces did not meet the criteria for high-level disinfected equipment. In all but one case decontamination of the head support resulted in a lowered bacterial load. There is a great need for evidence-based guidelines on hygiene in equine dentistry, including IPC measures, to decrease the risk of spreading infectious microorganisms between patients, facilities, and stables.

“…Currently, the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) classify 70 % or 90 % alcohol as a low-level disinfectant (Rutala & Weber, 2004, 2011, which is not enough for the management of semi-critical instruments or equipment, since it does not guarantee the complete elimination of microorganisms (Pereira et al, 2008;Ribeiro et al, 2015), because there may be microbial groups resistant to alcohol (Pinto et al, 2017). In spite of this, the commonly recommended process to disinfect IOCIs for clinical practice is the use of alcohol at a concentration of 70 % as an external disinfectant (Pereira et al; Ribeiro et al), always after a cleaning process in cases that they are subjected to high-level disinfection or sterilization (Rutala & Weber, 2004, 2011.…”

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 microbiological control makes it necessary to create a new categorization for these instruments when trying to comply with American Dental Association recommendations for dental practice.

Objetivo: Revisar o estado da arte sobre reprocessamento de produtos à luz dos estudos da Professora Kazuko Graziano. Método: Revisão integrativade literatura, tendo como descritor o nome da autora e com a seleção de 34 artigos. Resultados: Os estudos são abrangentes, majoritariamenteexperimentais e perpassaram pelos processos de limpeza e enxágue, desinfecção, esterilização e acondicionamento de artigos processados e em áreasemblemáticas para o reúso de materiais como ortopedia, oftalmologia, endoscopia e cirurgias videoassistidas. Conclusão: As evidências científicas dessesestudos são valorosas para o campo do reúso de produtos e para a qualidade e a segurança da prática assistencial na medida em que clarificam dúvidas esubsidiam mudanças de atitudesprocessos de trabalho. Esses estudos contribuem, também, para o controle sanitário de serviços de saúde ao subsidiar asVigilâncias Sanitárias com aportes teóricos sobre risco em reprocessamento de produtos e a Agência Nacional de Vigilância Sanitária (ANVISA) na atualizaçãoda política nacional de reúso de produtos para saúde (PPS) do país.
