Factors associated with the use of dental health services in primary care in northeastern Mexico.

In Mexico, as in many other Latin American countries, the use of dental health services (UDHS) has been scarcely studied, especially the one related with groups that are considered at risk in certain areas. The aim of this study was to evaluate the factors associated with UDHS in an at risk population in primary care. Material and Methods: Cross-sectional study, involving students (T), pregnant women (PW), workers (W) and older adults (OA) (n=368). Variables such as the use of dental health services and factors such as geographical, economic, and organizational barriers were measured. Descriptive statistics, Chi Square test and multivariate binary logistic regression analysis were used. Results: 40.2% (95% CI 30.2-50.2) of the W group had a history of UDHS in primary care, 20% (95% CI 11.8-28.2) of the PW group had spent more than a year without visiting the dentist and 33% (95% CI 23.7-43.9) had been treated at a private dental care service.
