Concordancia de los métodos Nolla, Demirjian y Moorrees para la determinación de la edad por medio de radiografías panorámicas

Abstract

Introduction: For a dental professional it is very important to have a knowledge of the real, chronological and cronoli age of a patient, and that according to this the necessary treatments can be defined for each particular case. Objective: Determination of the methods Nolla, Demirjian and Moorrees is more accurate to calculate the age of patients from 7 to 19 years to take into account the stages observed in the panoramic radiographs at the radiological center of the University Santo Tomás. Materials and methods: An analytical cross-sectional study was carried out from radiographic records of 97 participants who attended the dental clinics of the Santo Tomás University, Floridablanca, with chronological ages between 7 and 19 years old in the second semester of the year. 2017. Each participant was assigned with a code to ensure the confidentiality of their personal data, and each of the three methods (Demirjian, Nolla and Moorrees) was applied to the 7 left mandibular teeth of each participant. A descriptive analysis was carried out together with a bivariate analysis. For the Bivariate analysis, the result of each method to be studied was used (Nolla, Demirjian, Moorrees), and was compared with the chronological age in months and years recorded in the clinical history through an intraclass correlation coefficient. stratified analysis of estimated ages through the three methods by sex and race using a Student test and an Anova test. Finally, in order to evaluate the agreement, it was used to calculate the Bland & Altman agreement limits and the general agreement with respect to real age.Conclusion: In the Colombian population, Demirjian's method is the most accurate to determine the real age of adolescents.
