To assess the knowledge, attitude and practice of biomedical waste management among undergraduate dental students of a private teaching hospital in Chennai. Biomedical wastes are all wastes that are being generated during diagnosis, treatment or immunisation of human beings in the testing of biologicals and it's contaminated with human fluids. The waste generated by the healthcare workers during the treatment of patients is the most dangerous of all wastes and has a higher potential for infection and injury. This was an online questionnaire-based study, conducted on an online survey platform in April. The questionnaire was circulated among the Undergraduate dental students (third and fourth years and interns) of Saveetha dental college and hospitals, Chennai. The responses were collected and tabulated using the excel sheet and were exported to the SPSS software by IBM for statistical analysis. Among the interns, 85% had good knowledge and practice of biomedical waste management. 85% had a positive attitude towards the management of BMW. Amongst the final years, 80% had good knowledge, only 65% had a positive attitude and only 18% of the final years practice good BMW management. In the third year, 50% had good knowledge, 58% had a positive attitude and 58% had a good practice of biomedical waste management. The interns had good knowledge, a more positive attitude and good practice of biomedical waste management compared to the third and final years.
The term Nanotechnology involves a spectrum of technologies, techniques and processes that can deal with a matter at the nanoscale falling in between 1 nanometre to 100 nanometres in size. The concept of nanotechnology was introduced in 1959 by Richard P Feynman, a Nobel winning physicist. The aim of this research is to assess the knowledge and awareness of nanomedicine and its application in the field of dentistry among dental students. A cross-sectional study was conducted among 100 dental undergraduate internship students. The questionnaire contained 10 open-ended questions eliciting the knowledge and awareness about nanomedicine and its application in dentistry. The questionnaire was distributed via an online survey tool. The responses were collected and tabulated in the excel sheets, following which they were exported to SPSS software for statistical analysis. 52% of the students were aware of the term nanomedicine. 33% and 16% of the students had awareness of the nano modified impression material and nano modified denture teeth respectively. This study concluded that the knowledge and awareness of nanomedicine and its application in the field of dentistry was moderate among dental students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
