Current status of disinfection of dental impressions in Indian dental colleges: a cause of concern

Abstract

Introduction: Dentistry is predominantly a field of surgery, involving exposure to blood and other potentially infectious materials and therefore requires a high standard of infection control and safety practice in controlling cross-contamination and occupational exposures to blood-and saliva-borne diseases. Methodology: A questionnaire survey was conducted in 60 dental colleges throughout India to establish routine methods of treating impressions of the oral cavity for disinfection. An email describing the purpose of the study along with a short questionnaire was sent to one of the teaching faculty of concerned departments of the colleges. Questions were asked regarding availability of materials required to disinfect the impressions, the preferred method to treat the impression, and whether postgraduate courses were offered by the department. Results: The routine method of treating the impression reported by75.9% of the respondents was washing under running water, while 24.1% of the respondents reported that impressions were treated by chemical disinfectants. Conclusion: Strict infection control measures are necessary to ensure the health and safety of dental workers and patients. The present study showed that there is a lack of commitment to high standards of infection control practices in dental colleges in India.

Infection control knowledge and practice: A cross-sectional survey on dental laboratories in dental institutes of North India

“…Marya et al . [ 9 ] said that an impression, if not disinfected, can cross contaminate the entire laboratory area, allowing microorganisms to travel back and forth from the laboratory to the clinical area. Thus, it is essential for the laboratory technicians to disinfect all the impressions just to assure their own protection from infection.…”
