The study aimed at assessing the cooperation of orthodontists and dental technicians, in the field of disinfection procedures and identification of work stages that can cause transmission of cross‑infection at the stage of making and repair of orthodontic appliances. The research material was obtained via answers to survey questions provided by participants of the 21st Congress of the Polish Orthodontic Society and the 3rd Congress of the Polish Orthodontic Technician Society 2018. The obtained data were also analyzed in relation to scientific publications and binding law regulations. The survey concerned the decontamination of appliances in the office before handing them over to a patient and in the laboratory before handing them over to the office. Moreover, technicians were asked about using the same equipment and tools in the lab to make new and repair used devices, and frequency of polishing pumice replacement. The analyzed publications stated that pumice can be significantly contaminated with pathogenic microorganisms, and its daily replacement and disinfection should be obligatory. The duties of the orthodontic office and dental laboratory staff include proper disinfection of the made and repaired orthodontic appliances and written confirmation of the disinfection procedures carried out. It is necessary to learn and implement common, unified procedures for decontamination of impressions and appliances for orthodontic offices and technical laboratories.
