DENTAL PUMICE AS A SOURCE OF CROSS CONTAMINATION IN LABORATORIES: A MICROBIOLOGICAL STUDY.

Dr. K. Srinivasan, Dr. Chitra

Abstract :

 Aim and objective: This study aimed to determine the presence and level of microbial contaminants in pumice powder and slurry used in Dental laboratories. Materials and Methods: Ten active private Dental laboratories of Vellore entered in the study. Samples were randomly collected from Prosthesis polishing containers in sterilized condition and were immediately sent to Microbiology laboratory. Specimens were cultured on selective Bacterial and Fungal media in order to determine the type of Microorganisms present. Results: Results of this study showed, 100% contamination rate for pumice powders and 100% for pumice slurries. Frequencies of Gram positive and Gram–negative Bacteria isolated from the powders were 60% and 39% respectively. Frequencies of Gram positive and Gram–negative Bacteria isolated from the slurry were 64% and 34% respectively. This study showed that polishing pumice in the form of powder or slurry was contaminated with different oral and non oral Bacteria and also Fungi. Conclusion: The chance of cross–contamination still severely exists, and measures should be conducted to prevent the contamination in the predispose people such as Technicians, Dentists and patients.   Clinical Significance: The risk of cross–infection in Dental clinics and laboratories using contaminated pumice in polishing process of Dental prostheses may result in a non–safe environ­ment for Research and Medical care.
