Childhood is the stage of development where imitative behaviors are acquired par excellence and are preserved throughout life. A quasi-experimental study was conducted, which consisted of the application of an educational program on oral health promotion, (October 2015-June 2016), in children of the "Ignacio Agramonte Loynaz" elementary school, in the rural community of Larrondo. The level of information was determined through covert observation and the application of structured interviews to infants, parents and teaching staff. Then the "Educational Program for the Development of Correct Oral Hygiene" was applied; and finally, the level of information was determined once the program was applied. There was a change in the level of adequate information of both boys and girls, from 22.8% to 100%. The frequency of adequate brushing varied from 36.4% to 90.9%. Orientation to toothbrushing by professionals increased from 9.1% to 100% of the population. And the willingness of infants to help their peers was always present in the entire population.
