AB  - INTRODUCTION:The dental unit waterline (DUWL) is a source of infection in dental  clinics that must be controlled by chemical or non-chemical means. Multiple studies  have proven that hydrogen peroxide disinfectants lower bacterial counts in DUWLs.
AB  - OBJECTIVE: This study aims to compare the efficacies between E2O, a branded  DUWL cleaner, and a homemade cost-effective solution of 2% hydrogen peroxide in  reducing the DUWL heterotrophic bacterial counts of the clinical sections in the UP  College of Dentistry (UPCD).
AB  - METHODS: Six randomly selected dental units and their DUWLs from the three  sections (n=18) of the UPCD clinics were divided into two groups, E2O Treatment and  2% hydrogen peroxide solution. The DUWLs were flushed for 2 minutes with distilled  water and pre-test samples were collected. E2O and the 2% hydrogen peroxide  solutions were then run through the DUWLs, left overnight, and collected the next day  as post-test samples. Samples were spread-plated on R2A agar, incubated at 30±2ºC  for 7 days, and heterotrophic bacterial counts were determined. The Wilcoxon Rank  Sum test was used to determine if the disinfectants were able to reduce bacterial  counts to the Centers of Disease Control water standard of ≤500 CFU/mL.
AB  - RESULTS: E2O and hydrogen peroxide had mean bacterial count reductions of 53%  and 45.53% respectively with mean post-test bacterial counts of 1,401 CFU/mL and  1,616 CFU/mL respectively.
AB  - CONCLUSION: It is inconclusive to state that E2O Dental Waterline Treatment is  more efficacious than the homemade cost-effective 2% hydrogen peroxide solution or  vice versa. More research is recommended to conclude that these cleaners can  reduce bacteria counts in DUWLs when used regularly.
