Aim:

To evaluate a pedagogical method for the teaching of handwashing in dentistry students.

Methodology:

A quasi-experimental design was used, made in 2017,in which 26 students from the 2nd year of the Dentistry Department of the Faculty of Dentistry of the National University of Asunción participated, after presentation of informed consent, being 92% female and 96% right-handed. Hand washing evaluation was performed using the Artetesco ® brand of red paint, which was administered to perform a current washing by the student with eyes closed, the result was recorded and later the technique was taught systematized handwashing and repeated handwashing with the same material and applying the technique taught.TheMcNemar and Wilcoxon tests were applied with a confidence level of 95%.

Results:

The regions that showed a statistically significant difference were: Interdigital dorsum and left annulus (p=0.021), middle interdigital dorsu. The difference in favor of improving hand washing after the intervention was statistically significant.

Conclusions:

Every dental procedure is inherently linked to hygiene control practices, starting with hand hygiene, one of the ways to include in the teaching of this practice could be the use of tempera, quality of the handwashing technique. and left index (p=0.039), right interdigital dorsum (p(0.001), right side of the wrist (p(0.001), right side of the wrist (p(0.001), right side of the wrist (p(0.001), right side of the wrist (p(0.001).
