Dental laboratory workers face infection risks from un-disinfected dental prostheses. A disinfection protocol using chlorhexidine and chlorine dioxide effectively cleans dentures, safeguarding laboratory environments.

Area of Science:

  • Dental hygiene
  • Infection control in dentistry
  • Microbiology of dental prostheses

Background:

  • Dental laboratory personnel are susceptible to infections transmitted via contaminated dental prostheses.
  • Inadequate disinfection of dental devices poses a significant occupational health risk.
  • Microbial contamination of dental prostheses is a persistent challenge in dental laboratories.

Purpose of the Study:

  • To evaluate the efficacy of a specific disinfection protocol for dental prostheses.
  • To identify effective methods for preventing microbial contamination in dental laboratories.
  • To reduce the risk of infection for dental laboratory staff.

Main Methods:

  • A disinfection protocol involving a 4% chlorhexidine scrub (15 seconds) followed by a 3-minute contact time with a chlorine dioxide solution was applied.

  • The effectiveness of the protocol was assessed on contaminated dentures.

    • Main Results:

    • The combined chlorhexidine and chlorine dioxide disinfection method proved effective in eliminating microbial contamination from dentures.
    • The protocol successfully disinfected the dental prostheses, indicating its potential for practical application.

    Conclusions:

    • Chair-side disinfection of dental prostheses prior to laboratory procedures is crucial.
    • Implementing this disinfection protocol can significantly minimize microbial contamination risks in dental laboratories.
    • Protecting dental laboratory personnel from infection requires rigorous disinfection of all incoming dental devices.
