Purpose: Compare the microbial counts after two procedures of hands scrub, one with the technique of the World Health Organization (WHO), and another modified. Methodology: A study was performed with dentistry students of the University of Brasília, encompassing laboratorial and clinical steps. The samples were collected following the modified glove-juice method, and consisted of three periods: control - after hands washing with neutral soap, after hands scrub and in the clinic phase after the surgery. The students did the procedures with an interval of seven days. The data was analyzed with the computer statistic program Statistical Package for the Social Sciences, version 18.0. Results: Five students were included, which produced the inspection of 200 plaques. The techniques were similar in the laboratory step. The techniques were compared in the clinic step using the data from microbiological counts of control and after surgery; the hands scrub in both procedures had the same size effect (z Wilcoxon = - 3,92; p < 0,001; r = 0,88). Conclusion: Both techniques had similar results after the hands scrub and after surgery. The modified technique is faster and easier than the WHO's technique; these results could increase the practice of hands scrub by the surgery team
