Introduction:

Access to dental services is important to guarantee adequate oral health. Therefore, it is important to assess the geographical barriers that may affect access, such as altitude.

Objective:

Methods:

The variables were access to dental care, time of dental care, place of dental care, altitude, region, area of residence, place of residence, natural region, health insurance, wealth index, sex and age. A descriptive and bivariate analysis was performed with the chi square test. The results underwent multivariate analysis using Poisson regression to obtain prevalence ratios and adjusted prevalence ratios. There was a confidence level of 95% and p < 0.05.

Results:

It was found that altitude was linked to access to dental care (PR = 1.15; 95% CI: 1.12 - 1.18; p < 0.001), it was also found when considering the variables area of residence, place of residence, natural region, health insurance, wealth index, sex and age (RPa = 1.10; 95% CI: ºº1.04 - 1.16; p < 0.001).

Conclusions:
