Study of the degree of coincidence between chronological, dental and carpal ages in children aged 8 to 12 years

Abstract

The general objective of this descriptive observational radiographic and clinical study was to determine the degree of coincidence between the chronological, dental and carpal radiographic ages in a population of 40 children (20 boys and 20 girls), whose ages range from 8 to 12 years, who met the inclusion criteria of the research. To collect the information, weight, height, and panoramic and carpal radiographs of the right hand were taken from the 40 participants, who were also subjected to dental clinical inspection and intraoral clinical photography. To determine the carpal age, the Greulich and Pyle Atlas was used as a reference; to obtain radiographic age, the Demirjian method; The information on height and weight was used to determine height and BMI according to age with the help of standardized growth charts and according to the average growth in the Salvadoran population. Through the Student's T test, it was identified that, with respect to the means obtained, there was a significant difference between the dental, carpal and chronological radiographic ages in the majority of the population studied. In addition, it was observed that carpal age is found in the majority of girls, with respect to chronological age; however, in children it is decreased. Only 20% were identified in each of the population groups studied with early dental replacement.
