Abstract: La investigación tuvo como objetivo determinar el método más eficaz - Demirjian, Gleiser-Hunt o el análisis morfométrico - para la estimación de la edad en personas de 13 a 23 años, utilizando para ello el desarrollo radicular de las terceras molares inferiores. La muestra contó con 978 ortopantomografías de personas de edad cronológica y sexo (484 varones y 494 mujeres) conocidos. El método Demirjian mostró mejor concordancia - entre las medidas efectuadas en distintos momentos (k=0,777) – respecto al método Gleiser-Hunt (k=0,775). Asimismo, el análisis morfométrico también mostró una concordancia muy buena (CCI=0,967). El método Gleiser-Hunt obtuvo el mejor índice de correlación con la edad cronológica (r=0,864) que los otros dos métodos. De mismo modo, el mismo método Gleiser-Hunt fue más exacto (residual=1,55) que los otros métodos, por tanto, éste resultó el más eficaz. Se observó una tendencia respecto a la formación radicular más tempranamente en varones que en mujeres, característica que se observó por medio de los métodos Demirjian y Gleiser-Hunt. La diferencia entre la edad cronológica y dental fue de 1,55; 1,68 y 2,11 para los métodos Gleiser-Hunt, Demirjian y el análisis morfométrico respectivamente (utilizando para ello el mejor modelo de regresión múltiple). Hubo mayor probabilidad de que una persona sea menor de 18 años cuando sus terceras molares se encontraron entre los estadios A-E de Demirjian y los estadios 1-6 de Gleiser.-Hunt, asimismo, el análisis morfométrico mostró que hubo mayor probabilidad de que una persona sea menor de edad si presentaba una media proporcional de 0,5. PALABRAS CLAVE: Determinación de la edad, tercera molar, desarrollo dental, odontología forense.
--- The aim of this research was determine the most effective method - Demirjian, Gleiser-Hunt or morphometric analysis - to estimate the chronological age in people aged between 13 and 23 years, using the root development of the lower third molars. The sample consisted of 978 orthopantomograms from people with known chronological age and gender (484 men and 494 women). The Demirjian ethod showed better agreement - between the measurements made at different times (k = 0,777) - compared to Gleiser-Hunt method (k = 0,775). Moreover, the morphometric analysis also showed a very good agreement (ICC = 0,967). The Gleiser-Hunt method obtained the best correlation index in chronological age (r = 0,864) than the other two methods. In similarly, Gleiser-Hunt method was more accurate (residual = 1,55) than the other methods, therefore, this was the most effective. A trend was observed regarding the root formation earlier in men than in women, a characteristic that was observed by the Demirjian and Gleiser-Hunt methods. The difference between chronological and dental age was 1,55; 1,68 and 2,11 for Gleiser-Hunt, Demirjian and morphometric analysis methods respectively (using the best multiple regression model). It was more likely that a person is under 18 years old when his third molars were found between A-E Demirjian stages and 1-6 Gleiser-Hunt stages, also, morphometric analysis showed there was more likely for a person to be younger than 18 if that person yielded a proportionate mean of 0,5. KEYWORDS: age estimation, third molar, dental development, forensic dentistry.
