Purpose: The aim is to evaluate the bacterial contamination in dental unit waterlines (DUWLs) before and after the use of the disinfectant 1% (Lysoformin 3000) for its efficacy also assess the awareness about the same among the practicing dental surgeons of Vadodara city. Methodology: A volume of 20 ml water samples from the DUWLs from the clinics of the practicing dental surgeons of Vadodara city was collected. And were asked to answer a validated questionnaire in private. Disinfection of the waterlines was performed twice a week for 2 weeks with 1% disinfectant (Lysoformin 3000) and the samples were again collected. Qualitative and quantitative microbiological analysis was performed for both the predisinfected and postdisinfected samples. Results: Predisinfection samples showed a mean colony count of 670.35 colony forming unit (CFU)/ml which was reduced to 63.90 CFU/ml (P < 0.001) postdisinfection. Questionnaire assessment showed that 70% awareness of the participants about DUWL infections and the microorganisms associated. However, only 20% practiced any type of DUWL disinfection. Conclusion: Lysoformin 3000 can be promising to be used a DUWL disinfection solution as an easy to use and readily available solution with great antibacterial properties. However, still more long-term studies are required to check for its efficacy in anaerobic bacteria as well as resistant species of microorganisms.
