Background: The characteristics of the water lines of dental units (LAUD) allow the creation of biofilm that can cause cross infections between patients and health personnel. The use of chlorinated antimicrobial solutions added to the water tank for other purposes has been recommended. Purpose: To evaluate the antimicrobial effect of chlorinated solutions in tanks and LAUD of Dental offices in Barranquilla (Colombia). Methods: Descriptive study, conducted in 13 Dental units where the presence of microorganisms and the effect of the chlorinated solution on the microorganisms found after 14 days of use of the solution were observed from a first sample. Results: In the first sample, mesophilic growth greater than 200 CFU was observed in 66.6 %, total coliforms greater than 2 CFU in 58 %, E. Coli in 16 %, Pseudomonas in 33 % and fungal growth in syringe spray in 66.6 %. In the second sample, 25 % mesophilic growth was observed in the triple syringe. In the sprayer syringe 8.3 % and in the high part 8.3 %, no growth of total coliforms or coliforms was observed. E. coli, growth of pseudomonas was observed in 16 % in triple syringe and of fungi in 8.3 %. Conclusions: The chlorinated solution had an antimicrobial effect in the water tanks of the dental units included in this study. The microorganisms isolated in the present study are of clinical importance because they are associated with cross infections and different types of infections in humans.
