Introduction:

oral diseases increase with age, and their resolution implies a high cost not only at the budget level but also in terms of quality of life, which motivates the search for solutions through health policies that implement plans especially designed for this purpose.

Objective:

to determine oral diseases in first- grade students from “13 de Marzo" school in Santa Clara municipality, as well as the level of information of these children, their parents and teaching personnel.

Methods:

a mixed- method research was conducted between March 2017 and September 2018. It was carried out in two stages; methods and instruments were used to obtain the information, among which observation and interviews stand out. The sample made up of 57 infants, the same number of parents and 4 teachers was intentionally selected by criteria. We carried out interviews, observation, brainstorming, ranking method for prioritizing problems and triangulation of results.

Results:

presence of oral diseases in more than 80% of the sample where malocclusions stand out in a greater percentage than caries; an inadequate level of information on oral health in the studied individuals; absence of activities related to the promotion and education for oral health, as well as non-existence of play areas related to this subject, or brushing areas in the school.

Conclusions:

the children, parents and teaching personnel showed an insufficient level of information on oral health, and malocclusions were the most common condition found.
