Age estimation based on dental development is essential in clinical and forensic contexts, as it guides diagnostic, therapeutic, and medico-legal decisions. This study aimed to determine and compare the effectiveness of the Cameriere method and the modified Gleiser–Hunt method in estimating dental age and its proximity to chronological age in a Peruvian population aged 5–23 years. Digital panoramic radiographs from 220 individuals were analyzed: 76 aged 5–12 years and 144 aged 13– 23 years. For the Cameriere method, the distances between the internal surfaces of open apices (Ai) and tooth length (Li) were measured and normalized as xi=Ai/Li; for the modified Gleiser– Hunt method, maturation stages were assigned and the corresponding formulas applied. It was found that, in the 5–12- year group (Cameriere), accuracy was limited, with a mean absolute error (MAE) of 5.49 years; whereas in the 13–23-year group (modified Gleiser–Hunt), the MAE was 1.84 years, and the mean estimated age was 18.78 ± 1.23 years, indicating closer agreement with chronological age. We conclude that the modified Gleiser– Hunt method showed greater effectiveness for predicting chronological age in individuals aged 13–23 years compared with the Cameriere method, as it presented a smaller discrepancy between estimated and chronological ages.
