ABSTRACT
Assessing risk for transmission of a blood-borne pathogen requires the use of the hazard and risk model. Infection control is a system that uses a number of individual processes to eliminate or reduce the probability of a hazard occurring. Strategies employed to reduce risk should be rehearsed, used routinely, audited, reviewed, and the results shared. Continuing dental education has improved dental healthcare worker willingness to treat people living with HIV/AIDS (PLWHA) and has decreased negative attitudes and staff fears. Providing care for PLWHA during undergraduate dental school or dental hygiene programme is also associated with a greater willingness to treat. Whether by identifying suspect oral lesions or offering rapid screening tests in the dental setting for HIV, the dental team can play an important role in linkage to confirmatory diagnosis and care with the goal of reducing to zero the number of undiagnosed cases.

The physical and chemical stability of amphotericin B in a mixture of Fungizone and Optimoist was studied. The mixture was prepared by mixing equal volumes of Fungizone and Optimoist. The rate of sedimentation of amphotericin B was evaluated in Fungizone, Fungizone:Optimoist (1:1) and Fungizone:distilled water (1:1) mixture. The chemical stability of amphotericin B in a mixture of Fungizone:Optimoist (1:1) was determined by high-performance liquid chromatography from samples stored at different temperatures. The rate of sedimentation was faster when Fungizone was mixed with distilled water as compared to Optimoist. Amphotericin B was stable for three weeks stored in the refrigerator (4 deg C) and for three weeks at room temperature (25 deg C). Fungizone can be diluted with Optimoist for topical application. The mixture should be shaken well before administration in order to disperse any sediment.
