Abstract

Background & Aim: Impression making is one of the most common procedures that are performed by dentist in day to day practice. These impressions can act as vehicle of transmission and carry various type of microorganism. The aim was to assess the knowledge attitude and practice of current trends about dental prosthesis and impression disinfection method amongst dental laboratories; perspectives as per Covid-19 pandemic.
Materials and Methods: A survey was and the contact details of nearby dental laboratories were obtained from the State Registry of Indian Dental Association. Emails, contact number and postal address were recorded for study purposes. A questionnaire was designed to conduct the survey; it has total eight questions related to disinfection method used in dental laboratories as per COVID-19 perspective. The questions were prepared to include various aspects of disinfection method used by dental laboratories as per COVID-19 protocols. All data was sent for statistical analysis for further analysis and interpretations. P value less than 0.05 was taken as significant.
Statistical Analysis & Results: Statistical analysis was performed by using statistical package for the Social Sciences software. Results showed that out of 85 subjects who filled out the Google form, for the question item, “DO YOU DISINFECT THE DENTAL IMPRESSION?” maximum (67.1%) respondents selected the choice “YES” followed by the choice “SOMETIMES” as chosen by 28.2%. The significant difference was found in the proportion of various choice selections among the respondents. Out of 85 subjects who filled out the Google form, for the question item, “HOW DO YOU DISINFECT THE DENTAL IMPRESSION?”, maximum (29.4%) respondents selected the choice “WATER THEN SPRAY” followed by the choice “SPRAY AND IMMERSE” and “IMMERSE ONLY” as chosen by 21.2% for both.
Conclusion: Within the limitations of the study, it was concluded that practices and awareness among dental technicians regarding cross-infection control are very less than required, and this seems to increase the risk of transmission of diseases. This survey indicates that knowledge among the personnel participated in the study is less than ideal.
