| Descripción: | Objective: To determine the most effective dental age estimation method, Demirjian y Ubelaker, for estimating the chronological age in patients from 4 to 13 years of the National Institute of Child Health-Lima Peru. Materials and methods: Cross-sectional design with a sample consisting of 465 panoramic radiographs, 229 of male (49.2%) and 236 of female (50.8%). The estimated age was made using the protocol established in each method. The chronological age was established through the difference between the date of radiographic capture and the date of birth. The precision and accuracy of each method was established. The inferential analysis was performed with a level of significance of 5% through the Spearman correlation tests, Wilcoxon test. Results: It was proved that the Ubelaker method had 270 erroneous or mismatched cases and 195 coincidences while the Demirjian method had 360 erroneous cases and 105 coincidences between the estimated chronological age and dental age, finding significant differences in the estimation in each of the methods p=0.001 and p <0.001 respectively. The accuracy obtained with Ubelaker was 0,112 and with Demirjian 1,039. |
