The study was cross-sectional, descriptive, and retrospective. It was conducted using a total of 264 digital panoramic radiographs, with 116 from males and 148 from females, employing the Demirjian method to estimate dental age based on the inclusion and exclusion criteria established for the study, obtained from the Dental Imaging Center. The method is based on developmental stages by observing the mineralization state of the 7 lower left dental pieces and the score given based on the mineralization stage of each piece according to the Demirjian method. Results: A difference between dental age and chronological age was observed, with boys being 1.04 years ahead of their chronological age and girls being 0.9 years ahead. Conclusion: It was concluded that the Demirjian method provided better results for estimating dental age in the female population.

Comparison of the Nolla and Demirjian methods in the estimation of dental age in children, Period 2020
(Universidad Privada Norbert Wiener, 2022-08-15) Perez Rojas, Talia; Garavito Chang, Enna Lucila
The aim of this research was to compare dental age estimation using the Nolla and Demirjian methods in patients aged 6 to 12 years. The study was observational, descriptive, cross-sectional, and retrospective. The study population consisted of 278 digital panoramic radiographs. The technique used was observation, and data were collected in a data collection sheet, including radiograph number, sex, age, and analysis of Nolla and Demirjian methods, as applicable. The dental age estimation according to the Nolla method showed different values from chronological age with average values for the entire sample of 8.34±1.16. For the 7-year-old group: 6.52±0.8; 8 years (6.88±0.51); 9 years (7.52±0.49); 10 years (8.29±1.22); 11 years (8.78±0.57) and 12 years (9.44±0.34). The dental age estimation according to the Demirjian method showed different values from chronological age with average values for the entire sample of 9.47±1.88. However, within each group, the values were closer to chronological age, with the 7-year-old group: 6.60±1.0; 8 years (7.46±1.03); 9 years (7.82±1.02); 10 years (9.02±0.95); 11 years (10.27±1.33) and 12 years (11.77±1.10). It was concluded that when comparing chronological age with dental age, statistically significant differences were found with the age estimated by the Nolla method (p<0.0001) and also with dental age using the Demirjian method (p<0.0001).

Correlation of chronological age with bone and dental age in carpal and panoramic radiographs with the greulich and pyle atlas and the dermijian method in patients aged 6 to 12 years _ lima 2022
(Universidad Privada Norbert Wiener, 2024-08-21) Chagere Palomino, Carolina; Chero Guevara, Jorge Alfredo
The objective of this research was to determine the correlation between chronological age and bone and dental age in carpal and panoramic radiographs using the Greulich and Pyle atlas and the Demirjian method in patients aged 6 to 12 years in Lima, 2022. The study was applied, cross-sectional, retrospective, and correlational. The population consisted of 140 radiographs of patients aged 6 to 12 years of both sexes. Data was collected using a data collection form that included gender, age, sex, and the corresponding stage along with the atlas used. It was demonstrated that in the vast majority of cases, there is a correlation between chronological age and dental age, with dental age being higher than chronological age; however, in some cases, no correlation was observed, and only in a few cases was there a difference in dental age, which was lower than chronological age. Pearson correlation for chronological age was 1, and for dental age (CP), it was -0.301 with a significance of -0.398 (bilateral), and for bone age (CP), it was -0.098 with a significance of 0.789. It was concluded that there is a significant correlation between chronological, dental, and bone age at each point determined.

Relación entre la edad dental estimada por el método de Demirjian mediante radiografías digitales tipo panorámicas y la edad cronológica, de niños de 09 a 13 años de edad, Huánuco, 2016.
(Universidad Privada Norbert Wiener, 2018-01-09) Javier Mendoza, Jesús; Meza Balvin, Sandra
El objetivo de este estudio fue de determinar la correlación entre la edad dental estimada por el método de Demirjian mediante radiográficas digitales tipo Panorámicas y la edad Cronológica, en niños de 09 a 13 años de edad, Huánuco, 2016. Este estudio de metodología descriptivo, retrospectivo, trasversal y correlacional, analizó 90 radiografías digitales (43 mujeres y 47 varones), seleccionados en base a criterios de inclusión y exclusión. Donde el desarrollo dental fue evaluado con el método de Demirjian, el análisis Kappa reveló efecto no significativo en el momento de evaluar el error intraobservador (0.7525), a un nivel de significancia de 0.05, Se utilizó la correlación “r de Pearson“ para establecer la relaciónentre las variables. Resultando que existe correlación significativa, además de un coeficiente de correlación de r = 0.895. También se encontró que en el grupo de género femenino es mayor la correlación (r = 0.915), los resultados mostraron que no existe correlación de las variables para los grupos de edades de 09, 10 y 13 años. Concluyéndose que la edad estimada por el método de Demirjian mediante radiografías digitales tipo panorámicas resulto tener una correlación positiva alta con la edad Cronológica y se recomendó su uso para fines Forenses, mejorando el proceso de identificación humana en esta zona del Perú.
