Introduction and objective:

To determine the factors related to functional dentition according to the concept of the World Health Organization -OMS-and its prevalence in a group of elderly users of the dentistry service of the Central East Subred of Bogotá in 2017.

Materials and methods:

a cross-sectional study in which the functional dentition was taken as a dependent variable. By means of binary logistic regression, the independent variables that better explain the functional dentition were identified. The data were taken from clinical records filled by trained dentists and for the statistical analysis the software IBM-SPSS version 24 was used. We analyzed 394 clinical records of adults, older than 60 years, assessed in the dentistry service.

Results:

the prevalence of functional dentition was 17%. The multivariate analysis determined that the factors that best explained the functional dentition were sex (RP ^ 1.6), age (β ^ -0.08), presence of comorbidities (RP ^ 3.4), and use of dental floss (RP ^ 1,2)

Conclusions:

the data show a low prevalence of functional dentition in the studied population, being older, being a woman and not using dental floss, were factors related to lower functional dentition, while the presence of comorbidities on the other hand, it was associated with greater functional dentition in the study population. The findings of the study suggest the importance of strengthening the component of preventive activities throughout the life cycle, and even, from an early age to reduce dental loss.
