Dental unit waterlines may be heavily contaminated with micro-organisms and are potential source of infection for both practicing staff and immunocompromised patients. Contamination of dental unit waterlines could be inhibited with use of disinfectants.
Aim: To compare efficacy of aloe vera juice, listerine and sodium hypochlorite in controlling microbial contamination of dental unit water systems.
Methodology: After obtaining baseline water samples, the dental unit waterlines will be treated with aloe vera juice, listerine and sodium hypochlorite for one week. Water samples will be collected from 15 dental chair units from different departments. Water samples of 50 ml will be collected from outlet of airotar handpiece. Water samples were analysed for microbiological quality by total viable count method.
Results: Reduction in bacterial contamination after treatment with disinfectants has been found.
