An observational, descriptive and cross-sectional study, of 93 children aged 1-4 years registered in 5 non-state daycare houses in Sueño neighborhood of Santiago de Cuba was carried out from January to May, 2017, with the objective of identifying the risk factors which influenced in the oral illnesses that they presented.  To collect the information a schedule was made for this aim and an inquiry to parents and children was carried out, besides the oral examination to the last ones. Among the risk factors the cariogenic diet (96.7 %), followed by the use of the baby bottle (59.1 %) prevailed; also, the malocclusion turned out to be the most frequent disorder, mainly the increased prominence and the open bite.  Although the patients without disorders prevailed, they were exposed to these factors.  Therefore, it should be insisted in the previous diagnosis of malocclusions to minimize or to avoid their negative impact on the health of the children.
