Summary
Dental wastes are discarded materials after dental treatment which includes sharp instruments, infectious waste and body fluid, human parts, toxic agents, chemical, plastics body fluid etc. which are hazardous to health if not managed and disposed in proper way. In clinical dental practice many materials are used, which are either reused or discarded. Such discarded materials are considered as dental waste.[1,2] According to world Health Organization 2018, 15% of hospital related waste are hazardous.
