Evaluation of Hydrogen Peroxide and Cetylpyridinium Chloride as Bacterial Decontaminants of Dental Unit Water Lines at a Private Peruvian Dental School.

Aim: The aim of this study was to evaluate the hydrogen peroxide and cetylpyridinium chloride as bacterial decontaminants of dental unit water lines at a private Peruvian dental school.

Materials And Methods: Water samples were obtained from 66 dental units of a University Dental Clinic before decontamination treatment and at days 3 and 7 thereafter. The biofilm treatments were applied equitably among the two treatment groups ( = 22) and one negative control (distilled water).
