Age estimation presents a complex problem and requires considerable experience in recognizing significant changes and allowing for their variability with in any particular population. Tooth eruption and tooth calcification are the two events that can be used to measure dental age in children and adolescents. Although, Demirjian's and Nolla’s method are considered standard for dental age estimation, it may not be reliable for all population.
Aim: The goal of the study was to evaluate the reliability of Demirjian's and Nolla’s method of dental age estimation in determining chronological ages in younger individuals of Malaysian population based on developmental stages of third molar.
Study Design: A retrospective study was performed on panoramic radiographs of 100 subjects aged between14 to 22 years. Estimated age (EA) was calculated using Demirjian's and Nolla’s methods and compared with chronologic age (CA) for each patient.
Results: The mean of CA of the study sample was 18.5500 ± 2.36. Using the Demirjian method, the mean of EA was 18.8562 ± 2.10. For Nolla method, the mean of EA was 17.1625 ±2.11.
Conclusion: Hence the above results indicates that the Estimated age (EA) by Demirjian method was more close to chronologic age (CA) showing no significant variations between the two, Suggesting that the Demirjian method is more significant in determining age in younger individuals of Malaysian population.
