Objectives: To compare the chronological age and dental age according to Demirjian method in patients aged 5 to 16 who attended the Virgilio Aguirre Cadena Radiological Center, Guayaquil-Ecuador during 2014-2015 period. Material and Methods: A total of 617 Panoramic X-rays taken during 2014-2015 year were evaluated and dental age was calculated using Demirjian method for each one of patients. A comparative analysis was then carried out with chronological age taken from the same database of images, for which Wilcoxon test was used. Results: The estimates of dental age in relation to chronological age, observed on the female sex in 7-7.99, and 10-10.99 groups presented good estimates to determine the chronological age, it showed values ??of p = 0.6643 and p = 0.1147 respectively; regarding the male sex, the 10-10.99, and 12-12.99 groups showed good estimates to determine the chronological age on values ??of p = 0.2713, and p = 0.6996 respectively. The remainder of groups did not present good estimates to determine the chronological age with values of p<0.05.Conclusions: Demirjian method does not present optimum results, regarding bone age, in the groups studied, because the majority of the groups show a difference between dental age and chronological age.
