Comparison of Efficacy of Glutaraldehyde And U.V. Light Disinfection And Their Effect On Dimensional Stability of Polyvinyl Siloxane Impressions - An IN-Vitro Study.

Dental impressions need to be washed and disinfected immediately after making, to control transfer of infectious diseases from saliva and blood of the patient to dentists and technicians. Since sterilization of impressions is not possible because of high temperature and time needed, disinfection is the method of choice. But disinfection process may sometimes affect the properties of impression material. This study has undertaken to evaluate the efficacy and effect of chemical and U.V light disinfection on poly vinyl siloxane impressions.

Guidelines On Infection Control In The Dental Laboratory.

Infection control in the dental laboratory is an essential part of dentistry and is no longer an option but a requirement. The dental laboratory has been shown to be an area of potential disease transmission between patients and dental health care personnel i.e., dentists, lab technicians etc. potential pathogens can be transported to laboratory through microbially soiled impressions, dental prostheses/appliances. The increased awareness of infectious diseases and the recognition of the potential for transmission of numerous infectious micro organisms during dental procedures has led to an increased concern for and attention to infection control, in diseases to consider. This article reviews various methods and precautions to be taken towards infection control in the dental laboratory.
